GET/api/v1/feedback/token

Verify a feedback token

Redeems a presigned feedback token and records the feedback. `?token=efb_…` is required (400 if absent or malformed); optional `score` (0-10, 400 if out of range), `feedback` text, and a `key`/`value` pair merged into the token's metadata (`__proto__`/`constructor`/`prototype` keys are rejected 400). The token is matched by SHA-256 hash — there is no signature — and the call is SINGLE-USE: it stamps `used_at` under an optimistic lock and stores the submitted values. 401 INVALID_TOKEN when unknown, 401 TOKEN_EXPIRED past `expires_at`, 410 TOKEN_USED on replay. On success returns 200 with { message, projectId, traceId, score, feedback }. Authentication: none. This is a public endpoint and no credential is read. The empty `security` is a deliberate statement rather than an omission — nothing on this path resolves a caller, so no API-key scope is evaluated and an `eg_` key sent anyway is ignored.

Authentication

Public endpoint. No credential is read — send the request without an Authorization header. This is a deliberate statement, not a missing one.

Parameters

Response

{
  "success": true
}

All status codes

200Token valid.
400Bad Request — INVALID_KEY, VALIDATION_ERROR.
401(no description)
403Forbidden — the credential is valid but lacks the API-key scope, member role, or plan entitlement this operation requires.
409Conflict — CONFLICT.
410Token expired or already used.
429Too Many Requests — the per-key or per-organization rate limit was exceeded. Honour the Retry-After header.
500Internal Server Error — DB_ERROR.
