Message Failure Sources

When sending messages to the Channels API, /workspaces/:id/messages/:id, a message can end up in a failed status. The possible failure statuses are

• sending_failed

• delivery_failed

Errors are captured in the message reason field and also failure object. See the example below

"status": "delivery_failed",
 "reason": "details: unknown subscriber; reason: unknown_subscriber; code: 1",
 "direction": "outgoing",
 "details": "unknown_subscriber",
 "failure": {
   "code": 15005,
   "source": {
     "name": "sms-messagebird",
     "code": "1"
