Overview

Can be used as a callback target for messages. This makes it possible to receive a notification when a message is sent out.

For example, set up your outgoing message’s callback values as follows:

callback_url: http://howlr.example.com/delivery_notifications
callback_method: post

Now when the message is sent, a delivery notice will be sent back to the sender, informing them of whether the message was successfully sent out, or if some sort of delivery error occurred.

The real-world usefulness of this is probably questionable. It’s just meant to illustrate how a message callback receiver can be implemented.
