SMS Gateway

SMS Gateway is a portal application which will receive SMS Messages and relay them to a Web API. SMS Messages received will be posted to your Web Service API. The Web Service API contains the business logic as to what should be replied back to the original recipient. The Web Service API then makes a web GET request back to the SMS Gateway application. SMS Gateway then sends the response SMS back to the original recipient.
