Sending an SMS via SOAP (HTTP)

EnterpriseSMS API uses SOAP to authenticate requests and send SMS messages. Sending of SMS messages is done in two steps:


  • We strongly recommend SOAP method as the input and output variables are strongly typed, however at times using HTTP POST or GET is the only option. HTTP GET should, however be avoided as it is fraught with problems (string length, encoding issues, etc).
  • When using HTTP POST, be certain to retrieve the result of the request as it will contain valuable data that will assist in determining the message state.
