Integrating an existing application/system or building a new application for use with HSL's SMS delivery systems is relatively simple. A number of different interface protocols can be used over the Internet or via direct links which allow the sending and receiving of SMS messages.

The interface specifications for using HSL's services are contained in the Info & Docs section.

Tools for integrating mobile messaging into an application or for use in building a new mobile messaging application can be found in the SDKs and Components sub-section .

The Code Samples sub-section contains source code for demonstration applications that use a number of the interfaces to integrate with HSL's mobile messaging.
