Making Multiple API Calls for a Single Input Message using OpenAPI agent

[Atul227]

I want to run a query using the OPEN API that requires making multiple API calls based on a single input message.

Here’s what I need to do:

First API Call: Use the input message to retrieve a catalog ID from an API call specified in a JSON document.
Second API Call: Use the catalog ID obtained from the first call to perform another API call.
I'm having trouble implementing this process, so I would appreciate any help or guidance on how to set it up correctly.

I don't want to create 2-3 helper function just to do this because then it will loose the whole objective to have OPEN API agent.
