How To Display Zoho Forms in CRM

How To Display Zoho Forms in CRM

I'm trying to create a web tab in the CRM that displays an internal form and then routes it correctly using the form's integration.

The form is integrated with Zoho Desk. It works great and we've been using it independently for a few months now so I really don't want to go through completely resetting that all up. I'd like to embed this form in a web tab in Zoho CRM, but receive an error:

forms.zoho.com refused to connect.

When I add the public form, it works fine but then the Zoho Desk integration fails. I assume this is because the public form does not know who is completing the form where as the internal link only works for users logged into the Zoho environment and knows who the `Added User ID` is.

How can I get the form to display in a web tab and pass the added user id? I tried setting it as an appended parameter, but I may have the form field name wrong. I can't seem to find the correct field name for the added user id anywhere.
