## Request Format

Webhook requests conform to the [CloudEvents 1.0](https://github.com/cloudevents/spec/blob/v1.0.2/cloudevents/spec.md) specification using **HTTP binary content mode**:

- CloudEvent metadata is carried as `ce-*` HTTP headers (see parameters below).
- The request body contains only the event data payload (`call` object), encoded as `application/json`.
