Publish an event over the API

POST

/v1/endpoints/{id}/events

curl --request POST \
  --url https://api.hooks.events/v1/endpoints/example/events \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{ "payload": "example", "eventType": "example", "headers": { "additionalProperty": "example" }, "idempotencyKey": "example", "deliverAt": "2026-04-15T12:00:00Z" }'

• Production

API-key authentication replaces the inbound webhook signature. The event runs through the same normalization, filters, quota, fan-out and task triggers as /in/{publicId}. Send Idempotency-Key (or idempotencyKey) to collapse retries into the first event.

Requires the endpoints:write scope.
