Using a single HTTP POST operation, the external application can submit SMS(s) to the TEAM platform. Similarly, when receiving an SMS destined to an external application, the TEAM platform initiates an HTTP POST or GET operation to an URL defined by the system. The TEAM platform is HTTP version 1.1 compliant. All parameters in a POST request should be URL-encoded. An HTTP GET Request may also be used for sending, but is of limited use since a GET operation cannot hold more than 255 characters.
