How to call the REST API and print the response back in chatbot from Oracle Digital Assistant

I'm working on creating a custom skill to apply leaves from ODA.

Found an "API Services" option under settings and also found call rest services components in the dialog flow.

Do we have any documents or steps to use this feature.
