The .NET API is exposed as an interface named IApi and is defined in assembly AteSystems.InCal.dll.

It is written for .NET Framework 4.7.1

The referenced defined types can be found in the section: C# Defined Types

Published events can be found in the section: Published Events

The API Interface source code can be found in the section: IApi.cs

Referencing and using the API is a simple matter. A static reference to the API instance can be obtained from the InCal class. Once the reference is obtained you simply call the functions defined on the IApi interface. An example is shown here: API Call Example
