Prologue to iMsg Expert Message Gateway - Reseller API

Through iMsg Expert Message Gateway, you can register online and send your messages to mobile phones just in no time. To enjoy the functionality, you can send messages through our website directly to your contacts through uploading feature or adding contacts manually after successful registration on our website or you can integrate our API code into any of your application. Our online message gateway API creates the interface between your application and our message gateway through HTTP protocol.


To complete every request, you must have a product token, which is e-mailed to you subsequently to the registration. The token may look like (ad23eafe-fab7-4dda-aac7-92f1b19fbdc3).

Send a Message

Our API supports only HTTP requests to send the text messages, even you can integrate multi messaging system through multipart supporting API. Guidelines are given in Multipart section.


Messages longer than 150 characters are sent as a multipart message. At the time of sending long messages, we cut the messages into small messages making it easier to send but the phone pastes them together again to make it look like a single message. You can define 150 characters as minimum and 1200 characters as maximum message parts using the parameters such as:


Certain limitations are applied on the usage of multipart messages such as:

  • Each message can just contain up to 150 maximum characters.
  • SMS standard allows 255 messages parts, but you should not allow more than 8 messages parts so the maximum limit is 1200 only.
  • Not every operator handles the multipart message functionality. You must test for which operator it works for you.
