About NSP Public API
NSP Public API is an http-based API with an RPC-style method-syntax. All method responses are JSON, and in most cases the methods also expects JSON as parameter.
Any programming language and library can be used to make the http-calls and process the result. Familiarity with http-messages and JSON-format is recommended.
Nilex provides a .NET C# Winform-application that can be used as a reference and also as a utility to preview data in your local NSP system:
