Looking for help with Restful API calls

I would like to create a couple of pipelines to extract some details about my apps. 

Specifically, I want to create a pipeline using the Get tables for an app API call that will update the list of tables in another app.  I am planning to schedule this pipeline to run once a month.  I also want to create a pipeline that will use the table ids from the previous pipeline to create a csv containing the field names, fid, field type and relationship (if any).  Initially I will schedule this pipeline to run daily.

The API documentation doesn't contain detailed information.

Any suggestions are greatly appreciated.
