This project is read-only.


For communicating with friends and co-workers, the tool GroupMe ( is just quite perfect. There are clients available for the major mobile devices, additionally there is a perfect Html-App available on ther page.

As I tried to create a bot using their REST API, I soon realized that there are no .NET / C# libraries available which gives you a kick-start in using this API, so this was the hour of birth of this .NET SDK.

Sidenote: This SDK is an unofficial package, and was developed just in my spare-time. It is provided as a help for anyone who want to use GroupMe for creating applications :)



After some more hours of work, I can finally announce the first stable version 1.0.0 release of the GroupMe .NET SDK.

All major parts of the public GroupMe API are now implemented, including the following:
  • Groups management
  • Member of groups management
  • Group messages and direct messages support
  • Message like support
  • Bot management
  • Support for image, location and emoji attachments
  • Helper classes for authorization and emoji parsing / rendering

Also I finished the developer documentation for the package, it is available here:
or just use VisualStudio's Intellisense support.

To get the GroupMe .NET SDK into your project just add the CkSoftware.GroupMe.Sdk package using this command in the Package Manager Console:
Install-Package CkSoftware.GroupMe.Sdk 

or refer to the installation hints on the nuget page:

If you don't want to use NuGet, just download the release package here /releases/view/121414, extract the .zip into your solution directory and add references to all extracted .dll's.

That's it folks. If you have any issues or comments, please let me know.
