The workspace is resolved from the response itself, so the caller cannot choose which scope it is authorized against and no `workspaceId` parameter is accepted. An unknown or inaccessible `responseId` answers **403**, not **404**, so response ids cannot be probed for existence. **Round-tripping.** This read returns `data` in the stored, write-shaped form, so the simplest correction is to take it, change one entry and `PATCH` it back. Embedded Data round-trips through `embeddedData[]` instead: the `key` you read is the `key` a write accepts. `answers[]` is the typed view of the same information, offered alongside. Independently of that, a client working from a *list* row — which omits the maps — can still rebuild the write-shaped payload: `answers[]`, `embeddedData[]` and `unresolved[]` together carry every stored key and value **verbatim**, with no need to refetch the survey. Two rules make that guarantee hold, and both are contractual: `rawKey`, `rawValue`, `valueText`, `valueDate`, `fileUrls` and composite slot values are always the stored bytes, never resolved or reformatted — the resolved forms live in the separate `elementLabel`, `optionId`, `optionLabel`, `rowId` and `columnId` fields. And **empty-but-present values are returned, not omitted**: the `""` of an unchecked consent, the `""` of a selected but unfilled Other, a blank composite slot. That second rule matters because `PATCH` replaces `data` wholesale, so an omitted key is a deleted answer rather than an unchanged one. ## OpenAPI ````yaml /api-v3-reference/openapi.yml get /api/v3/responses/{responseId} openapi: 3.1.1 info: title: Formbricks API v3 description: > **Surveys**: **GET /api/v3/surveys**, **POST /api/v3/surveys**, **POST /api/v3/surveys/generate**, **POST /api/v3/surveys/validate**, **GET /api/v3/surveys/{surveyId}**, **PATCH /api/v3/surveys/{surveyId}**, **PATCH /api/v3/surveys/{surveyId}/blocks**, **PUT /api/v3/surveys/{surveyId}/blocks/order**, and **DELETE /api/v3/surveys/{surveyId}**. **Custom CSS**: survey CSS through `customCss` on **POST /api/v3/surveys**, **GET** and **PATCH /api/v3/surveys/{surveyId}**, workspace CSS through **GET** and **PATCH /api/v3/workspaces/{workspaceId}/custom-css**, and previews through `operation: customCss` on **POST /api/v3/surveys/validate**. Writes take and reads return source only; the server compiles it, returns removed constructs as top-level `warnings`, and never accepts compiled output. **Responses**: **GET /api/v3/responses**, **GET /api/v3/responses/count**, **POST /api/v3/responses/validate**, **POST /api/v3/responses/batch-delete**, **GET /api/v3/responses/{responseId}**, **POST /api/v3/responses**, **PATCH /api/v3/responses/{responseId}**, and **DELETE /api/v3/responses/{responseId}**. **Workflows extension**: **GET /api/v3/workflows**, **POST /api/v3/workflows**, **GET /api/v3/workflows/{workflowId}**, **PATCH /api/v3/workflows/{workflowId}**, **DELETE /api/v3/workflows/{workflowId}**, **POST /api/v3/workflows/{workflowId}/duplicate**, **POST /api/v3/workflows/{workflowId}/enable**, **POST /api/v3/workflows/{workflowId}/disable**, **POST /api/v3/workflows/{workflowId}/archive**, **POST /api/v3/workflows/{workflowId}/unarchive**, **POST /api/v3/workflows/{workflowId}/test**, **GET /api/v3/workflows/runs**, and **GET /api/v3/workflows/runs/{runId}**. Authenticate all management endpoints with **session cookie** or **`x-api-key`** (management key with access to the workspace). **Spec location:** source of truth is the multi-file tree at `docs/api-v3-reference/src/` (root `openapi.yml` plus one file per path and component); `docs/api-v3-reference/openapi.yml` is the generated single-file bundle (alongside v2 at `docs/api-v2-reference/openapi.yml`). **workspaceId** `workspaceId` is the canonical container identifier for this API. It is a **required query parameter on collection read endpoints** (`GET /api/v3/surveys`, `GET /api/v3/action-classes`, `GET /api/v3/contact-attribute-keys`) because those operate within a workspace. **`POST /api/v3/surveys` instead requires `workspaceId` in the request body**, not as a query parameter. Single-resource endpoints (`GET`/`PATCH`/`DELETE /api/v3/surveys/{surveyId}`) locate the resource by its globally-unique id and resolve the workspace from it, so they do **not** accept a `workspaceId` query parameter — sending one returns **400** with an `invalid_params` entry naming the key itself (`name: "workspaceId"`, `reason: "Unsupported field 'workspaceId'"`), rather than one naming the body. **Auth** Authenticate with either a session cookie or **`x-api-key`**. In dual-auth mode, V3 checks the API key first when the header is present, otherwise it uses the session path. Unauthenticated callers get **401** before query validation. **Pagination** Cursor-based pagination with **limit** + opaque **cursor** token. Responses return `meta.nextCursor`; pass that value back as `cursor` to fetch the next page. Survey list responses also include `meta.totalCount`, the total number of surveys matching the current filters across all pages. Workflow list responses do not require total counts in Scope 1. There is no `offset` in this contract. The page-size **maximum is 250** for responses, surveys, action classes and contact attribute keys; only the *default* varies by resource (20 for surveys, 50 for the workspace reference lists). **The workflows and workflow-run lists remain at 100** — their bound lives in the `packages/workflows` contracts and moves with that package, so each documents the value it actually enforces. A `limit` above an endpoint's maximum is rejected with **400** rather than silently reduced, consistent with v3 rejecting unrecognized query parameters instead of ignoring them. Callers should not infer the end of a collection from a page shorter than `limit`; `meta.nextCursor` of `null` is the only end-of-collection signal. Note that array-valued *input* bounds are a separate concern and stay at 100 — `filter[id][in]` and the batch-delete id list are bounded by write and payload risk, not by page cost. **Strictness** A query parameter that an operation does not declare returns **400**, with the offending key reported in `invalid_params[].name` — including on operations that declare no query parameters at all. Unknown parameters are rejected rather than ignored on purpose: a silently-dropped filter returns *more* data than the caller believes they asked for, and a typo in a filter name is indistinguishable from no filter at all. The same applies to request bodies, where unsupported fields are rejected instead of stripped. Unrecognized **headers** are tolerated, as gateways and proxies legitimately add them; strictness is about parameters and body fields, not transport metadata. This is the rule for the surveys, responses, tags and workspace reference-list operations. The workflows family does not enforce it today, so treat parameter strictness there as unspecified rather than guaranteed. **Request limits** A request body may be at most **2 MB**; a larger one is refused with **413** before it is read. Inside a body, **no array may hold more than 1 000 items, and all arrays together may hold at most 50 000 elements**, at any depth — a body that exceeds either bound is refused with **400** and a single `invalid_params` entry naming the offending array, before any field is validated. The same holds for nesting: a body may nest at most **256** levels of objects and arrays, counted from the root, and a deeper one is refused the same way, naming where it went too deep. Fields with a tighter bound document it as `maxItems` on the field (a survey's `blocks`, `endings`, `variables`, `languages`, `hiddenFields.fieldIds` and `distribution.triggers` since 0.2.0). A 400 or 422 lists at most **50** `invalid_params` entries; when there are more, the last entry says how many were left out. Since 0.2.0. **Filtering** Filters use explicit operator-style query parameters under the **`filter[...]` family**. The survey list supports `filter[name][contains]`, `filter[status][in]`, and `filter[type][in]`. The workflow list supports `filter[name][contains]` and `filter[status][in]`; the workflow run list supports `filter[status][in]` and `filter[isDryRun][eq]`. Resource-scoping identifiers (`workspaceId`, `workflowId`, `responseId`) stay plain query parameters. Multi-value filters use repeated keys or comma-separated values (e.g. `filter[status][in]=draft&filter[status][in]=inProgress` or `filter[status][in]=draft,inProgress`). Sorting remains a flat `sortBy` query parameter. **Responses** The response resource is **self-describing**. Answers come back as a typed `answers[]` array in which each entry carries the element's id, label, type and value, rather than as a map keyed by element id — so a consumer holding only a response can read it without fetching the survey and joining. Hidden fields, survey variables and auto-captured context are one `embeddedData[]` collection rather than three parallel concepts, each entry declaring a `kind` and a `type`. Data whose element has since been deleted is reported in `unresolved[]` instead of being dropped silently. Labels are resolved at read time against the current survey definition, and the `resolution` object discloses that policy along with the survey's `updatedAt` so a consumer can detect wording drift. Writes take answers in the **stored map form** (`data`) while reads return the typed array. Resolving ids into labelled answers is unambiguous; the reverse would mean matching caller-supplied labels back onto option ids, so the write side keeps the stored shape. To stop that costing round-trippability, the **detailed read returns `data` unchanged** — so a single-response read can be edited and sent back as `PATCH { "data": … }`, and the typed `answers[]` array is an addition rather than a replacement. One case where that round trip does not close: a write bound applies to `data` on the way in (`ResponseDataMapInput`) and none applies to the stored map, because v1 and v2 wrote it without one. A response carrying more answer keys than the write accepts therefore cannot be corrected through `PATCH` at all — the whole map is rejected, and sending a smaller one is not a workaround, because `data` is replaced wholesale and every key left out is deleted. Correct those through the v1/v2 management API or the dashboard. This is reachable only on surveys with more elements than the bound allows. Embedded Data is the exception, and it is symmetric rather than round-tripped: hidden fields and variables are read and written through `embeddedData`, addressed by **name** in both directions. No raw map of them is echoed, because a name is already what a write accepts — publishing the storage keys underneath (a variable's is its cuid) would expose a layout the caller has no use for. `data` therefore carries element answers only. Of those two, only `data` carries no `readOnly`, because it is the same map on the way in and on the way out. Embedded Data is writable through the **request's own** `embeddedData` map, not through the response field of that name — so `embeddedData[]`, like every other derived view on the resource, is marked `readOnly`, per its meaning of server-managed. `ResponseResource` lists them all. The list view omits `data`, since a bulk reader is not editing. `POST /api/v3/responses/validate` exists so a caller can see what a map would produce, and what a write would do, before committing to it. `createdAt` and `updatedAt` are **server-owned** on this resource: they cannot be supplied on create or changed by a patch. Response metering counts rows by `(surveyId, createdAt)`, and a client-chosen `createdAt` also lets rows be inserted into the middle of another consumer's already-paginated stream. Backdating stays available on v2 until a dedicated import path exists. The respondent's IP address and the `contactAttributes` snapshot that v1/v2 expose are not part of this resource in any view; that snapshot is copied from the contact at submission time and never refreshed, so it is stale PII by construction. Response filtering is allow-listed and index-backed: `filter[createdAt][gte|gt|lte|lt]` (at most one lower and one upper bound — `gte` xor `gt`, `lte` xor `lt`), `filter[finished][eq]`, `filter[language][in]` and `filter[id][in]`. `filter[finished][eq]` and `filter[language][in]` require `surveyId` or `contactId` as well, because both are heap residuals bounded only by an anchored index range. Per-answer, hidden-field, submission-metadata, contact-attribute, quota and tag filters are **not** offered; each is a JSON path or an unindexed join on the largest table in the product. The in-app dashboard does offer them, so this API is knowingly behind the dashboard here — closing the gap requires index work and is tracked separately rather than quietly omitted. `GET /api/v3/responses/count` answers "how many match?" directly. The list endpoint's `meta.totalCount` covers a caller that is already paging and is **opt-in** via `includeTotalCount` (default `false`, unlike the survey list) because responses are the highest-cardinality table in the product. Both response counts are **capped at 10 000** and carry an exactness flag — `meta.totalCountRelation` on the list, `data.relation` on `/count` — reading `eq` when the figure is exact and `gte` when the cap was reached and it is a lower bound. An exact count over this table grows superlinearly with the data while a capped one stays flat, so an uncapped total would be the only part of a response whose cost is unbounded. `/count` accepts `precision=exact` for the cases that genuinely need a precise figure, documented as the deliberate slow path. The survey list's `totalCount` stays exact and uncapped: surveys are low-cardinality and that count has a covering index built for it. Bulk deletion is `POST /api/v3/responses/batch-delete`, a custom method rather than a collection-level `DELETE`, so a call that loses its filters cannot degrade into erasing everything in scope. It scope-filters rather than rejecting: foreign and already-deleted ids are ignored and the call reports how many rows it removed, which keeps it both leak-free and safe to retry. **Security** Missing/forbidden workspace returns **403** with a generic message (not **404**) so resource existence is not leaked. Workflow and workflow-run detail endpoints also return **403** for unknown IDs or inaccessible IDs to avoid IDOR leaks. List responses use `private, no-store`. **AI survey creation** `POST /api/v3/surveys/generate` returns a draft `POST /api/v3/surveys` payload plus validation metadata. It does not create a survey. It generates survey content for both `link` and `app` surveys; for `app` it seeds a default `distribution` (display once, no triggers, no targeting) that you finish configuring before publishing. Prompt text is sent to the configured AI provider for generation, but it is not stored by this endpoint, not logged by default, and not included in audit data. **Feedback Records** `/api/v3/feedbackRecords` is served by the **API gateway** (Envoy on Formbricks Cloud, Traefik in the one-click Docker install), which authorizes each call against the dataset and forwards it to the feedback store — not by the application routes that serve the rest of v3. Three consequences: the payload is the store's own, so members and filters are **`snake_case`** (`tenant_id`, `value_text`) rather than v3's camelCase; the dataset is named **`tenant_id`** on the wire and is required on every collection operation (it is the feedback dataset id, which the MCP `list_feedback_datasets` tool reports as `dataset_id`); and errors come in two shapes — gateway refusals (**400**, **401**, **403**, **413**, **503**) are `text/plain`, while the store's own problems are `application/problem+json` with a stable `code`. These eight operations are the whole of the gateway-served surface; any other path it receives under the prefix answers **400**. Authenticate with **`x-api-key`**: the key needs a permission on a workspace the dataset is assigned to — `read` to list, get and search, `write` to create and update, `manage` to delete — and may update or delete only in a dataset assigned to exactly one workspace. **OpenAPI** This spec is **not** produced by `pnpm generate-api-specs` (that script only builds v2 → `docs/api-v2-reference/openapi.yml`). When the route contract changes, edit the files under `docs/api-v3-reference/src/`, then run `pnpm api:v3:bundle` to regenerate the committed single-file bundle. `pnpm api:v3:lint` lints the source tree; `pnpm api:v3:check` (CI) fails when the bundle is stale. **Workflows Scope 1** Workflows are a follow-up extension of the existing v3 Survey API work. The Survey API establishes API-first survey authoring; Workflows build on that same v3 style to automate actions around survey responses through workspace-scoped JSON definitions. Scope 1 models the existing Follow-ups capability as workflows: one `response.completed` trigger with an optional `endingCardIds` filter, and `send_email` actions with Follow-up email field parity. The definition and run shapes mirror the shared Zod schemas in `packages/workflows` (ENG-1100), which are the implementation source of truth for this contract. Workflows use `draft`, `enabled`, and `disabled` lifecycle states plus an `archived` soft-delete state. Status only changes through the lifecycle endpoints (`enable`, `disable`, `archive`, `unarchive`); it is not writable via `POST` or `PATCH`. Enabling validates that the definition is executable and snapshots an immutable workflow version; runs reference that snapshot via `workflowVersionId`. `POST .../test` is a dry run: it validates the definition and resolves the trigger's references synchronously, creating no run and sending no email, and returns `{ workflowId, ok, problems }` directly. Real runs execute asynchronously and are polled via `GET /api/v3/workflows/runs/{runId}`. **Overview migration note** The v3-backed survey overview page intentionally removes actions that are not yet exposed by this contract: `Created by` filtering, `Duplicate`, `Copy...`, `Preview`, and `Copy link`. **Next steps (out of scope for this spec)** Optional ETag/304, field selection, translation-specific writes, and survey version history. version: 0.2.0 x-implementation-notes: route: apps/web/app/api/v3/surveys/route.ts generate-route: apps/web/app/api/v3/surveys/generate/route.ts query-parser: apps/web/app/api/v3/surveys/parse-v3-surveys-list-query.ts auth: apps/web/app/api/v3/lib/auth.ts workspace-resolution: apps/web/app/api/v3/lib/workspace-context.ts workflow-contract-ticket: ENG-1101 workflow-shared-schemas: packages/workflows/src/types (feat/workflows-types) workflow-prisma-schema: packages/database/schema/workflows.prisma (feat/workflows-prisma-schema) openapi-generated: false spec-source: docs/api-v3-reference/src (regenerate bundle with `pnpm api:v3:bundle`) responses-contract-ticket: ENG-2868 responses-rfc: v3 Responses API RFC sections 2b (resource) and 2c (endpoints) responses-stored-shape: packages/types/responses.ts (ZResponse, ZResponseData, ZResponseInput) responses-prisma-model: packages/database/schema/main.prisma (model Response) pagination-model: cursor cursor-pagination: supported servers: - url: https://app.formbricks.com description: >- Formbricks Cloud.

Without it a client wanting to correct one answer would have to rebuild the map from `answers[]`, which is possible but is work the server can simply not impose. `answers[]` remains the field to read — it is typed, labelled and ordered, and it separates answers from hidden fields. This is the same data in the shape the write side speaks, offered alongside rather than instead. Present on the detailed view only. The list view omits it deliberately: on a page of 250 it would carry every answer twice, and a bulk reader is not editing. contact: anyOf: - $ref: '#/components/schemas/ResponseContact' - type: 'null' description: >- The contact that submitted the response, or `null` when the response is anonymous.

Everything in `ResponseListItem`, plus the identity and provenance fields the list view omits. It also carries `data` — the answers as stored, returned unchanged, so a client can read a response, edit an answer and send it straight back. Embedded Data is not echoed in stored form: the read's `embeddedData[]` and a request's `embeddedData` map already address the same fields by the same names, so a second raw map would only republish the storage layout. That is the property v1/v2 had for free by being symmetric, and the one OpenAPI 3.1.1 argues for directly: its "Validating `readOnly` and `writeOnly`" section notes that making clients strip fields before a write is "burdensome for clients, particularly when the JSON data is complex or deeply nested". They are not the *same* view, and the differences are deliberate. A write accepts `ingested` and `computed` fields only: a `reserved` entry describes the submission environment, and being able to read one back is not a licence to author it. An unset field is **omitted** from the read while `null` on a write **clears** one, because a merge-shaped map has no other way to spell deletion. And a name the read returns twice under different `kind`s cannot be written at all — see `ResponseEmbeddedDataInput`, which refuses an ambiguous name rather than guessing. Values themselves round-trip: within those two kinds every value the read emits is accepted verbatim on a write, and a `date` reads and writes as the same ISO-8601 string. So a read-edit-write cycle loses nothing except in two cases, both confined to rows v1 or v2 wrote. The first is the finite set of legacy surveys carrying one name as both a variable and a hidden field, where the write refuses the name outright. The second is a `data` map holding more keys than `ResponseDataMapInput` accepts: the stored map is unbounded and the write bound is not, so such a response cannot be patched here — and trimming it to fit is not a workaround, since `data` is replaced wholesale and an omitted key is a deletion. Note which fields carry `readOnly` here and which do not, because it is the opposite of what an "echo" framing would suggest. `readOnly` means a value is managed exclusively by the server, so it marks the **derived** views — `answers[]`, `embeddedData[]`, `unresolved[]`, `resolution`, the denormalized `surveyName` and `workspaceId`, the timestamps, `durationSeconds` and `id`. `data` is *not* read-only: it is exactly what the write endpoints accept, and leaving it unmarked is what makes this representation round-trippable rather than merely informative. To correct one answer, read this resource, take `data`, change the entry you want and `PATCH` `{ "data": … }`. Send only the fields you are changing — `PATCH` rejects unknown and non-patchable keys, so passing the whole representation back verbatim is not the intended flow; passing `data` back is. **Never exposed on this resource, in either view:** the respondent's IP address, and the `contactAttributes` snapshot that v1/v2 return.

Self-describing: `answers[]` carries each element's id, label, type and value, so a consumer can read a response without also fetching the survey.

This is the AIP-148 output-only convention, and it is deliberate on two counts: monthly response metering counts rows by `(surveyId, createdAt)`, and a client-chosen `createdAt` can insert rows into the middle of another consumer's already-paginated stream.

Absent when the submission carried no timing. Summing rather than reading `_total` is deliberate: the stored bucket is only written when a response is finished, so reading it would leave every partial response without a duration even when it carries per-element timing. This is also why the value can differ from the reserved `durationSeconds` catalog entry, which does read the bucket and rounds to whole seconds — that entry is not projected into `embeddedData[]`, so the two never appear side by side. resolution: $ref: '#/components/schemas/ResponseResolution' readOnly: true answers: readOnly: true type: array description: >- One entry per element the respondent reached, in survey order.

Hidden-field values do not live here. They are stored in the same underlying map, but that is a storage detail rather than part of this contract: a hidden field is an Embedded Data field, and Embedded Data is addressed by name through `embeddedData`. A hidden field's name appearing as a key here is rejected rather than silently written to the wrong namespace — with **422**, not 400, because knowing that a key names a hidden field means loading the survey, and these operations route every failure that needs stored state to 422. The problem carries `invalid_params[]` with `name` set to the offending key, `code: unsupported_field` and `referenceType: hiddenField`, so a client can point at it without parsing prose. A key that is **also** an element id is the exception, and it is **accepted**: the answer owns that address. Answers and hidden fields do share one slot, and the older surveys that declare a field named after a question have exactly one value under that key — but it is always the answer's. The field is dropped at ingest with `element_id_collision` (`packages/types/embedded-data-ingest.ts`) and filtered again in the renderer before it can reach a submission, precisely so a display-time field value cannot land on top of what the respondent answered. So on such a survey `answers[]` carries the value, `embeddedData` neither reports it nor accepts a write for it, and refusing the key here would block the only write that fits it. New surveys cannot reach that state through the editor or `POST`/`PATCH /api/v3/surveys`, which refuse an element id colliding with a declared field name. Both v1 management survey writes still accept one — that guard reads variable and hidden-field names but never element ids — so this set, unlike the reserved-name one, is still growing. Keeping the two apart is what lets the storage layout change underneath — the legacy columns go away eventually — without this contract either following it or breaking a round-trip it promised. The value shapes are the stored ones, and they differ by element type. `ResponseAnswer` documents each; `answers[]` on the read is the resolved view of this same map. **Bounds are a write-side concern and live on `ResponseDataMapInput`, not here.** This schema is the stored shape, and a read must describe what the API can actually return: the v1 and v2 write paths store this same map with no cardinality limit, so a response written through them can carry more keys — or a longer multi-select — than a v3 write would accept. Declaring the write bounds on this schema would make `GET /api/v3/responses/{responseId}` promise something it cannot keep for those rows. additionalProperties: $ref: '#/components/schemas/ResponseRawValue' ResponseContact: type: object description: > The contact that submitted the response, when the response is identified.

Answers are a **typed array**, not a map keyed by element id, because a consumer holding only a response would otherwise see bare ids and have to fetch the survey and join to learn what was asked — a join that is easy to get wrong and that agent clients cannot make cheaply. The array also separates answers from hidden fields and variables, which the stored representation mixes into one flat map. Non-answer data lives in `embeddedData[]`. Several element types share a value shape and therefore a schema — the four numeric scales, the four choice styles, the two composites. All seventeen element types are covered. Only elements the respondent actually reached appear here. Data whose element has since been deleted appears in `unresolved[]` instead. ResponseEmbeddedDatum: type: object description: > One piece of non-answer data carried by the response. Survey **variables**, **hidden fields** and **auto-captured context** are one concept here rather than three parallel ones: they all have a key, a provenance, a declared type and a label, and consumers treat them alike. Auto-captured (`reserved`) entries are drawn from the Embedded Data field catalog, which declares a privacy policy per field (`keep` / `drop` / `redactQuery`). Two of those act **before** this API sees the response, and one is a rule this API adds: - `drop` is an **ingest-time** policy, not a filter applied here: when the survey has "Anonymize responses" enabled the field is never captured, so it is absent from the response for every consumer. With anonymization off it is captured and appears here normally. - `redactQuery` is applied on **every** read, anonymization or not — `url` and `pageReferrer` carry their query string stripped. - `ipAddress` is **never** projected by this API, in any view. That is a v3 rule rather than a catalog behaviour: the catalog reads the field, and the dashboard shows it. Do not infer the same suppression for the other `drop` fields. Where a survey's own field and a catalog entry share a name, both appear — the declared one as `ingested` or `computed`, the auto-captured one as `reserved` — and `kind` is what tells them apart. Neither shadows the other, because each is a real value the response carries and dropping one would hide data the author can see elsewhere. Which catalog entries appear at all is a third axis, `display`, and this collection carries the ones that are not `none`. The `none` set is the response's own identity and timing — `responseId`, `surveyId`, `finished`, `language`, `durationSeconds`, `startedAt`, `finishedAt` — every one of which is already a first-class field on the response. Without that filter they would each appear twice in the same payload, once at the top level and once here. required: - key - kind - type - label - value properties: key: type: string description: > The field's **name** — what an author calls it, and the key `embeddedData` on a write accepts. Not the storage key. A hidden field happens to be stored under its name and a variable under its cuid, and that split is a property of the storage layout rather than of the field; exposing it would publish an internal id and make the writable and readable views of one field disagree on how to address it. **Unique per `kind`, not across the collection.** A survey created before the reserved names were enforced can declare a hidden field called `country`, and the auto-captured `country` still exists — so the same name can appear once as `ingested` and once as `reserved`. That set is finite and no longer growing: a new declaration may no longer take a reserved name, or the name of a variable or hidden field the survey already has. Key on `(key, kind)` rather than `key` alone, or read the pair you care about. kind: type: string enum: - ingested - computed - reserved description: > Provenance of the value: - `ingested` — supplied by the caller or the embedding page (hidden fields). - `computed` — derived during the submission by survey logic (variables). - `reserved` — auto-captured context from the submission environment (for example `country`, `deviceType`), drawn from the Embedded Data field catalog. type: type: string enum: - string - number - boolean - date description: >- Declared type of `value`, so a consumer need not infer it. `computed` entries are only ever `string` or `number`, because survey variables are typed that narrowly. label: type: string description: >- Human-readable name for the key, in the resolved language where one exists. value: oneOf: - type: string - type: number - type: boolean description: >- The value, matching `type`. `date` values are ISO-8601 strings. Always a scalar. A legacy row can hold an array or an object under a declared field's key — the ingest contract refuses those now, but older rows have them — and such a value resolves to nothing rather than being coerced, so the entry is omitted here and reported in `unresolved[]` with the bytes intact. Nothing is silently dropped, and no `type` would describe an array anyway. There is no `null` member: a declared key that resolves to nothing is **omitted** from the collection rather than carried with a null. So `embeddedData[]` enumerates what the response actually holds, not what the survey declares — a survey with twelve declared fields and two filled in yields two entries. A field with a default value is never unset, since the default is the fallback before the key is considered missing. additionalProperties: false ResponseUnresolvedEntry: type: object description: > Stored data that nothing in the current survey definition can account for. Deleting an element, a hidden field or a variable leaves its values behind on already-collected responses and nothing cleans them up, so the payload reports them here instead of dropping them silently or faking them into `answers[]` without a type or a label. Consumers doing analysis can ignore this array; consumers doing export or migration should not. **A declared field's `defaultValue` takes precedence over anything unreadable stored under its key**, and that is worth stating because this collection otherwise reads as exhaustive. Resolution falls back to the default before a value is ever judged unreadable, so a field that declares one always resolves — and the stored bytes, whatever their shape, are reported nowhere. Only a field with **no** `defaultValue` can reach `valueShapeMismatch`. A **scalar** under a defaultless field is not reported either, and the cause is the reporting guard rather than `locked`. Only `resolveEmbeddedValue` consults the lock; the guard that decides what reaches this collection admits objects only. So an uncoercible scalar — `"yes"` under a boolean field — resolves to nothing and is then excluded for being a scalar, lock or no lock. A non-scalar under a lockless, defaultless field is what does reach `valueShapeMismatch`. Neither omission is a silent drop by accident — one follows from resolution order, the other from the reporting guard — and both are written down so a consumer does not read `unresolved[]` as a guarantee that nothing was left behind. If either proves to matter in practice a reason code can be added without breaking anyone, whereas removing one could not — which is why this is documentation rather than a guess at a fifth enum member. required: - key - rawValue - reason properties: key: type: string description: >- The key as stored on the response. For `elementNotInSurvey` it is a former element id or hidden-field name; for `variableNotInSurvey` a variable's cuid, since that map is keyed by id rather than by name; and for `valueShapeMismatch` the id or name of the element or declared field that *does* still exist — that reason means the key resolved and the value did not. rawValue: $ref: '#/components/schemas/ResponseRawValue' description: >- The stored value, returned verbatim and untyped because nothing describes it any more. reason: type: string enum: - elementNotInSurvey - variableNotInSurvey - valueShapeMismatch description: > Why the entry could not be resolved: - `elementNotInSurvey` — nothing in the current definition claims this key. It covers a deleted element **and** a deleted hidden field, because the two cannot be told apart: an answer is stored under its element id and a hidden field under its name, in one shared map, and storage keeps no record of which kind a vanished key used to be. - `variableNotInSurvey` — no variable with this id exists in the current definition. Variables *are* distinguishable, because they live in their own map keyed by cuid rather than sharing the answer map. - `valueShapeMismatch` — the key resolves to a current element **or a declared Embedded Data field**, but the stored value's shape cannot be read as an answer of that element's type (for example a string where the element expects a selection list).

Read at request time from the current definition — see `ResponseResolution` for what that means for older responses. durationSeconds: type: number minimum: 0 maximum: 86400 description: > Seconds the respondent spent on this element. Converted from the stored per-element time-to-complete, which is recorded in milliseconds. This telemetry is reported by the client and is therefore not trustworthy input: treat it as an indication rather than a measurement. Absent when the submission carried no timing for this element. The bounds hold on **every** row, including ones collected before the write-side clamp shipped. The stored representation is deliberately unbounded so that historical data still parses, and a row written then can hold a negative value or a tab left open for days; those are clamped into range on read rather than returned as-is, because a schema a real row violates is worse than a slightly blunted outlier. So `86400` means "at least 24 hours", not exactly. ResponseSelection: type: object description: > One selected option within a choice-style answer. `optionId` plus `rawValue` is deliberately a two-field split — the same split the Hub stores as `value_id` plus `value_text` — because option ids are stable while labels are editable and language-dependent. Consumers that need to group or compare across time should key on `optionId`; consumers rendering to a human should use `optionLabel`. required: - optionId - optionLabel - rawValue - match properties: optionId: type: - string - 'null' description: >- Resolved option id, or the literal `other` for a write-in. `null` when `match` is `unmatched`. optionLabel: type: - string - 'null' description: >- Option label in the resolved language. `null` when `match` is `unmatched`. rawValue: type: string description: >- The value as stored on the response, verbatim and before resolution — always present, and the string to use when rebuilding the stored map. Note what is stored differs by element type: `multipleChoiceSingle`, `multipleChoiceMulti` and `ranking` store the option **label** in the respondent's language, while `pictureSelection` stores the option **id**. `""` occurs when the respondent selected Other and left it blank, and is returned rather than dropped. match: $ref: '#/components/schemas/ResponseValueMatch' rank: type: integer minimum: 1 description: >- 1-based rank, present only for `ranking` elements. Array order already reflects the rank; this field makes it explicit so consumers need not rely on ordering. additionalProperties: false ResponseValueMatch: type: string enum: - exact - label - other - unmatched description: > How a stored raw value was resolved against the current survey definition. Precedence is fixed and applied in this order: - `exact` — the stored value matched an option **id** in the current definition. - `label` — the stored value matched an option's **label text** (ids are stable, labels are editable and language-dependent, so a label match is weaker evidence). - `other` — the value arrived through the element's **Other** free-text input. Only reported when the element actually has that input enabled and the value was submitted through it. - `unmatched` — no option resolves. The raw value is still returned; it is **not** silently reclassified as `other`, because a *renamed* option is also unmatched text and filing it as a write-in would misattribute the answer. responses: V3BadRequest: description: >- Bad Request — malformed JSON, invalid query/body/params, duplicate name, or unsupported field. headers: X-Request-Id: schema: type: string description: Request correlation ID Cache-Control: schema: type: string example: private, no-store content: application/problem+json: schema: $ref: '#/components/schemas/Problem' V3Unauthorized: description: Not authenticated (no valid session or API key). headers: WWW-Authenticate: schema: type: string example: Bearer realm="formbricks" description: >- Authentication scheme challenge. RFC 9110 §15.5.2 asks a 401 for a challenge "applicable to the target resource", and Bearer is applicable here because these operations accept the API key as `Authorization: Bearer ` as well as `x-api-key`. Session-cookie-only operations send no challenge — see `V3UnauthorizedSession`. The MCP endpoints send a richer OAuth challenge carrying `resource_metadata` and `scope`.

Equivalent in every way — same key, same workspace permissions — and offered because it is what most HTTP clients and SDK generators reach for by default. A **401** from any operation that accepts it carries `WWW-Authenticate: Bearer realm="formbricks"`. Session-only operations accept neither this nor `x-api-key`. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
