This event is fired every time we receive a confirmation of delivery from a carrier, the status field indicates how the text has been delivered. To receive these events your system must have capability for processing a large number of simultaneous requests, we forward such events in real time as soon as we receive it from carriers.

The data payload format is the Message Log Object.

Note: If we never received any confirmation from carriers, we do not generate any receipts on our own.
