HTTP GET Protocol

We also maintain a gateway interface that can be addressed using a HTTP GET method. This call is limited in its features and only supports the basic parameters (FROM, TO, BODY and REFERENCE), options such as concatenation (multipart), unicode, and hybrid messaging are not supported. We advise to use our HTTP POST call if possible.
