Use the ThingWorx APIs and/or download our many SDKs for any platform to develop your first prototype and test drive our robust IIoT platform.
The full power of the ThingWorx Foundation server is available through HTTP requests. This REST API documentation shows how to create, update and delete Entities as well as discover and execute available services.

Build robust, secure, full-featured edge integrations and gateways for any platform using the C, .NET, Java (supporting Android development).


The C SDK is the basis for ThingWorx Edge SDKs and the Edge MicroServer (EMS). You can compile C SDK applications on any platform and even run it without an operating system. Using the C SDK for your application means least amount of RAM, processing power, and disk space, frequently requiring less than 200 kilobytes. The C SDK is also the only SDK that is distributed as source code.

Java SDK

The Java SDK is especially useful if you are integrating with an application that uses a Java-based API. While applications based on the Java SDK tend to use more RAM, processing power, and disk space than a C SDK equivalent application, they typically take less time to develop. To use it, you will need a platform with a supported Java Virtual Machine. The Java SDK support Android development.


Use the Microsoft .NET SDK when integrating with a .net based application or if your team typically works with Microsoft technologies. It may only be used on Windows based machines.
