webhooks

Rotate webhook signing secret

Generates a new signing secret for the endpoint and returns it exactly once: store it immediately, it cannot be retrieved after this response. For 24 hours every delivery is signed with both the old and the new secret, so a receiver verifying with either keeps working while you roll the new one out. After the window the old secret stops signing. Verification details are in the webhooks guide.

An endpoint holds at most 5 concurrently valid secrets, so rotating repeatedly within the overlap window fails with WebhookTooManySecrets until an older secret expires.

Headers

Idempotency-Keystring

Client-supplied key. On operations supporting request deduplication, a retained response is replayed for duplicate requests with the same key within the idempotency window (3 hours by default). This protection requires a workspace, organization, or staff-account scope. User-only and unscoped unauthenticated operations, streams, and operations with a separate replay contract do not use this response replay.

On a supported operation, if idempotency protection is unavailable before execution, the API returns 503 IdempotencyUnavailable (E01033) without executing this attempt. Retry with backoff using the same key and request. An operation that takes effect before its response is retained can still execute again on retry.

Two distinct 409 errors signal misuse:

  • request_in_progress (E01004): The same key is currently being processed by a concurrent request. Wait briefly and retry. The lock expires within 30 seconds.
  • idempotency_key_reuse (E01005): The same key has already completed against a different request body or method. Generate a new key.

Recommended key format is <event-type>/<entity-id> (for example welcome-user/usr_abc123).

X-Workspace-Idstring

Workspace context for the request. Required for dashboard authentication and master keys. Workspace keys and access tokens already identify their workspace; send that workspace or omit the header. A different one is rejected.

X-Organization-Idstring

Organization context for the request. Required for dashboard authentication. An API key or access token carries its own organization, so send either that organization or no header at all; a different one is rejected.

Response

New signing secret.

secretstring required

The new signing secret (whsec_ prefix). Shown only in this response: store it immediately, it cannot be retrieved again. Deliveries are signed with both this and the previous secret for 24 hours after rotation, then the previous secret stops signing.

Example response

{
  "secret": "whsec_newbase64encodedvalue"
}
