# message.sent

`POST message.sent` (webhook)

A message was sent from a mailbox, from any app or the API.

Pro and Business plans. `message_id` is the message's permanent id: pass it to `GET /mailboxes/{address}/messages/{uid}` (and the flag, move, spam, delete and attachment routes) in place of a UID. It does not change when the message moves folder.

Partner endpoints receive this only for customers where you hold a mailbox key with `mail:read`, and as a pointer (`mailbox`, `message_id`, `thread_id`, `folder`, `received_at`): fetch the message with that key.

## Headers
