get_message_receipt

URL: https://api.postageapp.com/v.1.0/get_message_receipt.json

If you need to confirm that message with a particular UID exists within your project just send a request with the following:

{ "api_key" : "PROJECT_API_KEY",
  "uid" : "uid_of_the_message"
}

If message is found you'll get this response:

{ "response" : {
    "uid" : "uid_of_the_message",
    "status" : "ok"
  },
  "data" : {
    "message" : {
      "id" : "1234567890"
    }
  }
}

If it was not found:

{ "response" : {
    "status" : "not_found",
    "uid" : "uid_of_the_message"
  }
}
