I'm trying to get a Zoho Sign webhook to work with a standalon REST API function in Zoho CRM.

The webhook set up in Zoho Sign is calling the function, but I don't know what I need to name the argument in order to receive what Sign is sending.

I looked at the documentation, but it's not clear what argument to give the name of the function so as to get the object that the webhook is sending. I looked at this help article but it's still not very clear what is sent.

Does it send anything? If it does, how do I access it in a Zoho CRM function?

Thanks!
