Introduction
The eCOS® API allows you to programmatically interact with the eCOS® system.
You can use it to perform a variety of tasks such as retrieving existing data, creating or modifying resources, and triggering automated actions.
There are many methods available, but you will typically use just a few of them to perform a specific task.
