Outgoing Webhooks

Endpoint

Outgoing webhook management (supervisor/admin only). Delivery is at-least-once: events are captured durably (Redis stream) and retried with exponential backoff, so the same event may be POSTed more than once (e.g. after a transient receiver/network failure or a dispatcher restart). Receivers must be idempotent — deduplicate on the event's natural identifiers in the JSON body (timestamp plus the relevant id under data, e.g. data.message.id / data.conversation_id) together with the X-Omnistream-Event header, and verify the X-Omnistream-Signature HMAC. Do not assume exactly-once. Deliveries that exhaust all retry attempts (default 8, capped exponential backoff) move to a dead-letter queue (status = dead_letter) and can be replayed. During a secret-rotation overlap window each delivery carries two signatures — X-Omnistream-Signature (new secret) and X-Omnistream-Signature-Previous (old secret); accept the delivery if EITHER header matches the secret you have stored.

Start a signing-secret rotation

POST

https://api-chat.misindo.id

/api/outgoing-webhooks/{id}/rotate-secret

Supervisor or admin only. Stages a new HMAC secret and opens a 24-hour overlap window: deliveries are signed with the NEW secret in X-Omnistream-Signature and with the OLD secret in X-Omnistream-Signature-Previous, so receivers can switch secrets without dropping deliveries. Complete (or cancel) the rotation explicitly, or it auto-promotes after 24 hours. The new secret is returned once in this response and never again.

secret

Complete a pending secret rotation

POST

https://api-chat.misindo.id

/api/outgoing-webhooks/{id}/rotate-secret/complete
