Webhook Events

Email sent

A mail left through the email API. Exactly one event per mail, whichever path sent it: source is send, reply, forward, draft or scheduled. A scheduled draft carries both scheduleId and draftId.

Use it to record sends in your own system with the metadata you passed. The sent copy also arrives as message.sent in the inbox.

Changes

Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
