POST /api/v1/webhooks/{id}/ping
Send a test event.
- Scope
webhooks:write - Idempotency-Key
- operationId
webhooksPing
The token needs the scope webhooks:write, and the person or service account behind it needs the matching privileges and account permissions, exactly as on the screens. See Scopes.
Idempotency-Key. Send a unique Idempotency-Key (up to 255 characters, e.g. a UUID) with every POST. Retrying with the same key and body replays the first answer for 24 hours, so a timeout never creates a second order; the same key with a different body is refused (idempotency_key_reused).

Status codes and errors
Errors are application/problem+json (RFC 9457) with a stable code to program against; the detail says what to fix. See Errors.
| Status | When | Problem codes |
|---|---|---|
| 202 | Accepted: a job (or the file) is being processed | |
| 200 / 201 | The same Idempotency-Key again: the first answer is replayed (24 hours) | |
| 400 | The request is malformed | invalid_request |
| 401 | No token, or it is invalid or expired | invalid_token |
| 403 | The token lacks the scope, or the person or service account behind it lacks the privilege or account permission | insufficient_scope forbidden ip_not_allowed |
| 404 | Not found, or not visible to you (the API never confirms what you may not see) | not_found |
| 409 | Not possible in the current state | invalid_transition conflict idempotency_in_progress |
| 422 | Validation failed (the detail says which field), or blocked | validation_failed idempotency_key_reused |
| 428 | A required header is missing | idempotency_key_required |
| 429 | Rate limited: wait for Retry-After seconds | rate_limited |
