ZSubscriptions-ZCreator integration. Description of payload.

ZSubscriptions-ZCreator integration. Description of payload.

In the ZC integrations with ZS we have:
<response> = zoho.subscriptions.getList(<module>, <orgID>)

How/where do I find the decription of the "payload" returened by this?  
Need to know how the respons look like in order to handle it in ZC with the executeXPath function in ZCreator.

Thank you.
