A successful API request generates an HTTP 200 response. The response to a request where output format was specified as json, is a JSON array with response status and unique identifier.

{ 
  "response": {
    "id": "3914460380512464906-350465300787800379",
    "phone": "919777777778",
    "details": "", "status": "success"
              }                         
 } 
                           
                        

This indicates that the message has been successfully sent to mobile number 919777777778 under a Unique Identifier ‘3914460380512464906-350465300787800379’. The identifier string is unique for each recipient number and is auto generated at the time of message submission. First number is the transaction ID and second one is message ID. If a custom msg_id is passed in the API request (say, msg_id=1343891), it would be set as the message ID and returned back in the API response message as the second half of the unique identifier. For instance, the ‘id’ parameter would be ‘3914460380512464906-1343891’.
