Rotate a webhook endpoint's signing secret

POST /v1/webhook-endpoints/{endpoint_id}:rotate-secret · permission webhook-endpoints:write · all plans

Issues a new signing secret and returns it once (Cache-Control: no-store). During previous_secret_ttl_hours (default 24) every delivery carries two signatures in the webhook-signature header, one with the old and one with the new secret, so you can switch your receiver without losing deliveries. 0 drops the old secret immediately (for a leaked secret). A request repeated with the same Idempotency-Key returns the endpoint without the secret and with secret_redacted: true.

Request

Field Type Required Description
endpoint_id path yes Webhook endpoint ID (whe_…).
If-Match header no When given, must match the endpoint's current ETag.
previous_secret_ttl_hours integer no 0–168 hours the old secret keeps signing; default 24. The body is optional.
Idempotency-Key header no Replays the response (without the secret) for a repeated request with the same key. 
{
  "previous_secret_ttl_hours": 24
}

Response

200 OK with the endpoint, its new ETag and the new secret.
