SMS status callback
Payload sent by SignalWire to your SMS Status Callback URL when the status of an SMS/MMS message changes.
Configure this callback using the `StatusCallback` parameter when
[sending an outgoing message](/docs/compatibility-api/rest/messages/create-message).
There are 8 possible message statuses:
| Status | Description |
|--------|-------------|
| `queued` | The API request was processed and the message is waiting to be sent. |
| `sending` | The message is being transmitted to the nearest upstream carrier. |
| `sent` | The nearest upstream carrier has accepted the message. |
| `delivered` | The nearest upstream carrier confirmed receipt of the message. |
| `undelivered` | SignalWire received notice from the upstream carrier that the message was not delivered. |
| `failed` | SignalWire could not send the message. There is no charge for failed messages. |
| `receiving` | SignalWire has received and is currently processing an inbound message. |
| `received` | The inbound message has been received by a number in your account. |
<Note>
SignalWire only marks a message as `delivered` when it receives a Delivery Receipt (DLR)
from the receiving carrier confirming entry into the end carrier's network. `sent` means the message
left SignalWire and reached the downstream peer. Some carriers send delayed DLRs; others send none
at all. MMS messages never receive DLRs, so they will only ever reach `sent` status.
