Omitted top-level fields are preserved. Provided top-level objects and arrays replace that whole subtree; this endpoint does not deep-merge nested objects and does not implement JSON Patch. This write endpoint accepts the canonical multilingual authoring document only. Translatable fields must be locale-code maps, not strings. `PATCH ?lang=...` and `?version=...` are not supported in Scope 1. For MCP and AI-agent workflows, fetch the current survey first, modify only the intended top-level fields, call `/api/v3/surveys/validate` with `operation: patch` for preflight, then submit the same patch here. Missing ids in replaced arrays are treated as deletions. Variable name renames are allowed but may be destructive for downstream exports or integrations. Element id changes are rejected once the survey and element are no longer drafts. Server-owned fields that `GET` returns (`id`, `workspaceId`, `type`, `createdAt`, `archivedAt`, `defaultLanguage`, `languages[].alias`) are accepted and verified, so the output of a `GET` can be sent straight back. Echoing the value you were given is a no-op; changing one is a **422** `read_only_field`. A round-tripped `updatedAt` acts as an optimistic-concurrency precondition: the write is applied only if the survey has not changed since your read, and is otherwise rejected with **409**. Omit it and overlapping writes remain last-write-wins. Header-based preconditions (`ETag` / `If-Match`) are still future work. ## OpenAPI ````yaml /api-v3-reference/openapi.yml patch /api/v3/surveys/{surveyId} 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**.

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.

Five cases: 1. The target survey is archived (soft-deleted) and therefore read-only; restore it before editing. The `invalid_params` entry reports `name: archivedAt` with the reason `This survey is archived. Restore it before editing.` 2. The patched document passed schema validation but failed a cross-reference check that requires stored state to detect: an undeclared locale key used in content, a duplicate stable id, an immutable element-id change on a published survey, a dangling logic/jump reference, an invalid media URL, a `distribution.triggers[].actionClassId` referencing an action class that does not exist in the workspace (discover valid ids via `GET /api/v3/action-classes`), or a `targeting.filters` entry that cannot resolve in the workspace — an unknown contact-attribute key or segment, an unsupported person identifier, or an unknown device value. The `invalid_params` array pinpoints each issue (e.g. `code: invalid_reference` with the offending `identifier`). A patch that newly *introduces* a forward reference — a recall of an answer not yet given, a logic condition reading a later block, or a `requireAnswer` target that is not in a later block — is refused with `code: misordered_reference`; a survey that already contains one stays patchable, only newly created violations are rejected. A patch that newly *introduces* a loop in the conditional logic — jumps, fallbacks and next blocks leading back on themselves, so a respondent could never reach an ending — is refused the same way, reported at the `logic` of each block a new looping step leaves ("Cyclic logic detected in block N"). A survey that already loops stays patchable, and blocks that only lead into a loop are fine. 3. A server-owned field was echoed back with a different value — `code: read_only_field`, with the submitted value in `identifier`. Sending the value `GET` returned is always a no-op. 4. The *stored* survey cannot be read as a v3 document at all — `code: stored_survey_invalid`. The reported paths are into the survey, not into the request; repair it in the editor. A stored survey that reads fine but already fails validation (a missing translation, a dangling recall) stays patchable: only issues a patch newly introduces are refused. The exception is publishing: moving a `draft` out of `draft` still requires a survey that passes, and is refused as `stored_survey_invalid` while it does not. 5. `customCss` could not be processed (a syntax error, the 20 000-byte survey budget, a complexity limit). `invalid_params` names `customCss.light` / `customCss.dark`; `details.errors` carries the processor's located errors.
