API Connectivity

Our API solution supports submitting messages, receiving delivery reports and receiving inbound SMS messages (two-way SMS) over HTTP and SMPP modes. To find out more about our technology, please click here.

For HTTP API, messages are sent to the syntax URL provided via HTTP POST or GET methods. We recommend using the POST method since GET operations can be limited in size and may be truncated by browsers or intermediate proxies.

Using the SMPP API, please follow SMPP 3.4 protocol document which can be found at Please note we do not provide test scripts for sending messages via SMPP. Consult your web developer for setting this up using any of the dynamic scripting languages including ASP, PHP and Java.
