Description

Adds the Formbricks integration: all 46 catalog operations, verified against a live
Formbricks Cloud workspace rather than transcribed from documentation.

Fixes #775

Formbricks is a survey platform. This plugin lets an agent author and publish a survey,
read responses back, keep contacts in sync, and manage webhook subscriptions.

Operations: 46 catalog ids, 47 registered operations, 38 distinct routes.

Group Ops Notes
Surveys 4 update is what publishes - it moves draft to inProgress
Responses 4
Contacts 8 includes the two ids the catalog still lists as "people"
Contact attribute keys 7 includes the two listed as "attribute classes"
Contact attributes 1 values, read-only
Action classes 2
Webhooks 5 managed as a resource - see triggers below
Teams 3 teams, plus workspace-team assignments
Account / roles / health 6
Client API 5 displays, user identify, environment, respondent state
Storage 2 public and private upload grants

Why 47 operations for 46 ids. Formbricks renamed "people" to "contacts" and
"attribute classes" to "contact attribute keys" and removed the old routes, but the
catalog still lists both names. contacts.listPeople, contacts.getPerson,
contactAttributeKeys.listClasses and contactAttributeKeys.getClass are aliases
calling the same URLs
as their current-name counterparts, so no catalog id 404s for a
caller working from the older entries. They are not four extra capabilities. A test
asserts each alias still points at its primary's route, and that each emits its own
audit event so the two stay distinguishable in a log.

One operation, contactAttributeKeys.update, claims no catalog id - it edits an
attribute key's definition, which the catalog has no id for.

Triggers: 0. Formbricks does have outbound webhooks, and this plugin manages them
as a resource, but the OSS catalog lists no triggers so no Corsair webhook handlers are
registered.

Auth. One API key, sent as x-api-key. Key scope decides reach: an
organization-scoped key is rejected by GET /v1/management/me with a 400 pointing at
/v2/me. Most management routes need a workspace-scoped key.

Two live API versions. v1 and v2 are both current and neither is a superset -
contacts expose only GET on v1 and only POST on v2. Version is chosen per operation by
what each route actually serves.

Pagination is per route, and getting it wrong is silent. The wrong parameter is
accepted with a 200 and discarded, so this was established by seeding rows and comparing
returned ids, not by reading status codes:

  • v1/management/surveys advances by offset - the only route in the API that does.
  • Everything else pageable advances by skip.
  • Four v1 routes ignore limit too and return every row, so those operations expose no
    paging parameters rather than advertising ones the API discards.

The meta envelope reports an offset field even on routes that ignore offset, which
is what makes reading the envelope misleading. Callers say offset everywhere; the
plugin translates to the wire name per route.

Persistence: 5 entities mirrored - surveys, action classes, webhooks, contact
attribute keys, teams. All configuration. Responses, contacts, contact attributes and
displays are deliberately not mirrored: they are collected from survey respondents.
An attribute key is configuration and is cached; an attribute value is somebody's
email address and is not.

Privacy. Respondent answers, contact attribute values and userIds are sent where
the API needs them and never logged - audits record key names and counts instead. A
webhook create returns a signing secret that no later read returns; it is passed to the
caller and stripped before mirroring. Storage returns S3 presigned POST fields carrying
X-Amz-Signature; same treatment. Tests assert each of these directly, including a
sweep that runs every operation against a response poisoned with respondent data.

Schemas built from live responses, captured 2026-08-15, with a test asserting every
captured field is declared. Only the primary key is required, because Formbricks omits
or nulls fields by plan and survey type and a rejected row is a lost row.

Verification

lint / typecheck / validate:plugins / validate:docs   clean
build                                                 36.73 KB
unit tests                                            250 passed, 3 suites
live tests                                            27 passed, real workspace
catalog coverage                                      46/46 ids, 0 missing

The live suite writes and cleans up: each test creates what it needs, deletes it in a
finally, and the suite compares eight resource counts before and after - a leftover
fails the run. It is excluded from a default run and self-skips without a key.

Scope

30 files in packages/formbricks/, plus packages/corsair/core/constants.ts at
exactly +3/-0 and pnpm-lock.yaml. Nothing else touched.

Known limitations

Stated rather than hidden - all Formbricks-side, all verified by effect:

  • Several documented filters are accepted and ignored. GET_RESPONSES takes
    contactId, startDate/endDate/filterDateField and sortBy with a 200 and
    applies none of them; LIST_WEBHOOKS rejects surveyIds as a string, accepts
    surveyIds[]=, then ignores it. Not declared in the input schemas - a contactId
    filter that silently returns every respondent's answers is worse than a missing one.
  • GET /v1/management/contacts cannot be paged at all and returns every contact in
    the workspace. GET v2/management/contacts is a 405, so there is no alternative.
  • UPDATE_CONTACT_ATTRIBUTES has no management route - five candidates answer 404
    or 405. Implemented over the client user route, so it is keyed by userId and creates
    the contact if that id is new. Marked write and non-idempotent for that reason.
  • Two upstream 500s, both worked around: a bulk upload containing an unknown
    attribute key, and PUT /v1/management/responses/{id} sent without data (the schema
    requires data to turn that into a local validation error).
  • The documented 207 partial-success on bulk upload was not reproducible - it answers
    200, or rejects the whole batch with 422.
  • Self-hosted instances are supported through a host option but were not exercised;
    only Formbricks Cloud was.

The catalog descriptions are also environment-scoped throughout (environmentId) while
the live API takes workspaceId. That affects every operation's input, not only the
renamed routes.

Checklist

  • I have run pnpm lint and all checks pass
  • I have run pnpm typecheck and there are no TypeScript errors
  • I have run pnpm build and all packages build successfully
  • I have run pnpm test and all tests pass
  • I have added or updated tests where applicable
  • I have added or updated necessary documentation

Additional Notes

No new dependencies. No changes outside the plugin beyond the three registration lines
in constants.ts and the lockfile.

Core changes I deliberately did not make, to keep the diff in scope: the pagination
translation and the presigned-upload handling both live in the plugin rather than in
core, even though other plugins may hit the same shapes. Happy to lift either into core
in a follow-up if you would prefer that.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 22131

This PR adds a broad Formbricks integration for surveys, contacts, responses, webhooks, and uploads. At the current head, validation failures may expose respondent email addresses in logs, workspace selection can produce rejected writes, and the privacy tests do not fully prove the stated redaction guarantees. These are concrete privacy and correctness risks that should be fixed or explicitly accepted before merge.

Place the caller body before workspaceId.

{ workspaceId, ...body } lets a workspaceId key in body override the explicit argument. If that key holds undefined, compactBody then removes it, and the write is sent without the field. Formbricks answers a 400 in that case. Spreading body first keeps the explicit argument authoritative.

1656-1670: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Two gaps weaken the privacy sweep.

First, poison returns primitives unchanged, so an operation whose payload is a scalar array gets no planted values. roles.list (payload ['owner', 'member']) therefore passes its privacy assertion vacuously. The guard test at lines 1694-1702 uses object payloads only, so it cannot detect this.

Second, the comment at lines 1704-1707 states that respondent data must not reach a cached row, but the loop asserts only POISON.secret. Widen the assertion to the respondent values, or narrow the comment to the secret. If a mirrored entity schema keeps unknown keys, widening will fail; confirm which fields FormbricksSurveyEntity, FormbricksTeamEntity, and FormbricksActionClassEntity keep before choosing.

♻️ Proposed change to make scalar payloads detectable
 		const poison = (payload: unknown): unknown => {
 			if (Array.isArray(payload)) return payload.map(poison);
-			if (payload === null || typeof payload !== 'object') return payload;
+			// A scalar payload cannot carry planted fields, so the planted answer replaces it.
+			// Without this, an operation returning bare strings asserts nothing.
+			if (payload === null || typeof payload !== 'object') return POISON.answer;
 			return {

The Formbricks Client API endpoint GET /api/v1/client/{workspaceId}/environment (and its v2 counterpart) returns a response object that includes an expiresAt field within its top-level envelope [1][2]. This expiresAt timestamp is used by Formbricks SDKs to determine when the client-side configuration state needs to be refreshed [2][3]. Key details regarding this field and the endpoint's behavior: - Purpose: The expiresAt value instructs the SDK on when to recheck the server for updated environment configurations (such as surveys, action classes, or workspace settings) [1][2]. - Cache TTL: Recent updates have reduced the cache Time-To-Live (TTL) for this endpoint to 1 minute across Redis, CDN, and browser layers to ensure faster propagation of configuration changes [2]. While the infrastructure cache is short, the SDK typically uses the expiresAt value to manage its own internal re-synchronization cycles [2]. - Structure: The response is typically wrapped in an envelope where data contains the core workspace configuration, and expiresAt is provided alongside it to manage the lifecycle of that data in the client [1][2]. Note: The terminology in the API path has transitioned from environmentId to workspaceId, though environmentId is often supported as a deprecated alias for backward compatibility [4][5].

Handle the environment payload before generic unwrapping. GET client/{workspaceId}/environment returns sibling top-level data and expiresAt fields. unwrap treats this as an envelope, returns only data, and drops expiresAt.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Do not log the raw error message for validation failures.

The file header states that ApiError's message embeds the response body. Formbricks returns respondent data inside validation bodies. packages/formbricks/endpoints/types.ts lines 323-326 record the observed 422 for contacts.uploadBulk: "Duplicate emails found in the records", listing the addresses. VALIDATION_ERROR writes error.message to console.warn, and describeValidationFailure appends body.message as well, so respondent email addresses reach the log.

That contradicts the privacy rule the plugin states for respondent data. Log the status and the field names only. The other handlers that log error.message (PERMISSION_ERROR, NOT_FOUND_ERROR, SERVER_ERROR, NETWORK_ERROR, DEFAULT) share the same exposure, so apply the same treatment there.

🔒 Proposed fix: log field names, not bodies
 export const describeValidationFailure = (error: unknown): string => {
 	if (!(error instanceof ApiError)) return '';
 	const body = error.body as
 		| {
 				message?: string;
 				error?: { message?: string; details?: unknown };
 				details?: unknown;
 		  }
 		| undefined;
 
 	// v2: details is an array of {field, issue}, which names what to fix.

Quick heads up before you review.

The Formbricks docs do not match their actual API. I found seven places where they disagree.
If you check my code against the docs, those seven will look like mistakes - they are not. For
example: the docs use one field name, the API wants a different one. The docs list filters that
the API accepts and then silently ignores. The docs point file uploads at a route that rejects
everything.

I tested every operation against a real Formbricks account instead of trusting the docs, so where
my code and the docs differ, the code follows what the API actually does. I can walk through any
of the seven if you want the detail.

Two things you might want changed:

  1. There are 47 operations for the 46 in the catalog. Four are duplicates - the catalog still
    lists some things under old names Formbricks has since renamed. I added both names so nothing
    is missing, but I am happy to delete them if you would rather keep it lean.
  2. Four list operations have no paging. Formbricks ignores paging on those routes and returns
    everything, so adding the option would have been misleading.

All 46 operations are implemented and working. 251 automated tests, plus 28 that run against a
live account and clean up after themselves.

Keep the YAML transformer in the Formbricks package.

Line 17 imports test tooling from the sibling packages/corsair package. This makes packages/formbricks depend on a repository-relative layout. Move the transformer into packages/formbricks or use a declared package dependency.

As per coding guidelines, each plugin must remain self-contained within its own packages/&lt;plugin&gt;/ package, except for required registration in packages/corsair/core/constants.ts.
