There is not a specific component to work with APIs. They are, by their very nature, custom to each use case, so unless you see a component for the specific application you are working with, you are going to need to program to it. There are various components for calling web services (both REST and SOAP) as well as the Script component that allows you to write some C#. In some cases, you'll need to write more extensive C# and create a component.

Hi Thomas, 

Thanks for the clarification. Meanwhile I came across this thread

Could successfully import the Json and RestClient Util from the .Net Framework components.
