Zapier with shared apps

Zapier with shared apps

Hi!
I'm trying to figure out if Zoho Creator can help me create my app.
It is an app for lead management, with a three level user tier. 
- I am the app owner.
- I share the app with my client.
- He will use it for followup with his client.
- He will need to set up Zapier to transfer the leads into the app he is using.
- He can not have access through Zapier to the other apps I have.

The question is, is that possible at all?
I tried to do it, but it gave some error, specified ownername is not valid, or something. I guess that Zapier needs access to the app owners account to set it up, not just to a shared user's account.
Am I right?
