SyntaxTree, a third party company that is not officially supported by FastSpring but who is a FastSpring client, has released their C# (.net) libraries for integrating with FastSpring.
- SyntaxTree.FastSpring: A library to validate the license requests and different notifications that FastSpring performs.
- SyntaxTree.FastSpring.Api: A library to query the REST API that FastSpring exposes, currently limited to the scope that SyntaxTree is using.
Both libraries are licensed under the permissive MIT/X11 license.
