The API uses SOAP based web services so you can develop in any programming language including HTML5, C++, C#, ASP.NEY, PHP, Pearl, TCL/TK and others. But if you are looking for the most flexible and powerful development environment to date, we recommend you use Adobe® Flash® / Flex Builder and ActionScript 3. In fact our MonsterSignage application was developed in Adobe® Flash® Builder and so we provide a working project that you can import and get up and running in seconds.
Flash® / Flex Builder is a highly productive, open source framework for building expressive mobile, web, and desktop applications. It allows you to build web and mobile applications that share a common code base, reducing the time and cost of application creation and longer term maintenance.
