Registers an active webhook endpoint that receives the event types in events as signed HTTPS POST requests. See the webhooks guide for delivery, signing, and retry behavior.

The 201 response is the only response that includes the signing secret (whsec_ prefix). Store it immediately; if it is lost, rotate the signing secret.

A non-HTTPS or non-public url, an unknown event type, or exceeding the organization's endpoint limit returns 422.

Payload della richiesta

url
string

HTTPS URL to deliver events to, at most 2048 characters. The host must be publicly reachable: URLs on private, loopback, or link-local addresses are rejected with a 422. Required unless destination is a connector, whose URL comes from the connector and its config; a URL given with one must equal it.

filter
object

Limit delivery to one mailbox and only email_mailbox events. Omit to include all resources.

Mostra parametri secondari
events
array of string
obbligatorio

Event types to subscribe to; the endpoint receives only matching events. Types outside the event catalog return a 422, and an endpoint holds at most 100 entries.

description
string

Human-readable label for this endpoint, up to 256 characters.

destination
object

How each delivery is built. Omit to post the signed event to url unchanged, the same as {"type": "webhook"}.

Payload di risposta

id
string
obbligatorio

Unique identifier for the endpoint (whk_ prefix). Accepted as webhook_id by every /v1/webhooks/{webhook_id} operation.

HTTPS URL where the API delivers events for this endpoint.

description
string

Human-readable label for the endpoint.

filter
nullable object

Mailbox scope configured through filter, or null.

Mostra attributi secondari
events
array of string
obbligatorio

Event types this endpoint is subscribed to; only matching events are delivered. Change the set with Update a webhook endpoint.

status
string
obbligatorio

Delivery state of the endpoint.

  • active: The initial state; events are being delivered normally.
  • degraded: Recent deliveries are failing. We keep delivering and retrying, and the endpoint returns to active automatically once deliveries succeed again.
  • paused: All delivery is stopped, either because an update set status to paused or automatically after sustained delivery failures. A paused endpoint never resumes on its own: re-enable it with Update a webhook endpoint, then Replay failed deliveries to recover the deliveries that failed before the pause. Events that arrived while it was paused were never attempted, so a replay does not reach them.

Possible values: active, degraded, paused

destination
object

How each delivery to the endpoint is built.

created_at
string
obbligatorio
updated_at
string
obbligatorio
secret
string
obbligatorio

Signing secret for this endpoint (whsec_ prefix), used to verify every delivery signature. Present in this response only: store it immediately, it cannot be retrieved again. If you lose it, mint a new one with Rotate webhook signing secret.

next
array of object

What to do next with this endpoint. Empty: deliveries start as the events happen, with nothing left to set up.
