### Responses for message API

#### In case of success

```
{ 
   "status": "success", 
   "message": "Request received successfully.", 
   "data": { 
       "id": "6929d4af-490d-454a-8cf3-0502a3506f09" 
   } 
} 
```

This id in response is message id for future response. All the message status updates on webhook will be mapped to this id. So store this message id at your side.

#### In case of failure

```
{ 
   "status": "failure", 
   "error": { 
       "code": "8006", 
       "message": " type is required." 
   } 
} 
```

According to error code and message will change.
