Client Libraries and SDKs

Labs64 maintains open-source client libraries (Apache License 2.0) that wrap the NetLicensing REST API for Java, C#/.NET, PHP, JavaScript/Node.js, Kotlin and C++. They handle authentication, request encoding and response parsing, so validating a customer is a single method call. For other languages, such as Python, Go or Ruby, call the REST API directly or generate a client from the OpenAPI specification.

Contributions are welcome. Use each project’s issue tracker for bugs and feature requests, or contact us at netlicensing.io/contact.
