I need to be able to update the information in an application when I make an update on a different application on a different account. 

My question is,  Is there a way to use the built-in integration tasks (Zoho OAuth connection)?  Or must I set up my own rest API process for the integration?

What I tried so far.

I have my own application that I am trying to receive records from, and I am a developer on a different application. 

I set up a Zoho OAuth connection on the latter application and used it in a "zoho.creator.getRecords" task in that application 

This gives me an error of  "{"code":1130,"message":"You do not have permission to access this application's APIs. Please check with the application admin."}"

This doesn't make sense to me because I am the owner of the application that task is trying to access.  I get the same error when I log in as the owner of the application I run the task from.
