Display a Zoho Form in a Web Tab

Display a Zoho Form in a Web Tab

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

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 link to the form, it displays properly in the web tab 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 Zoho 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 as the logged in Zoho CRM user? I tried setting it as an appended parameter, but I may have the Zoho form field name wrong (no API docs that I've found).

I can't seem to find the correct field name for the added user id anywhere. Please don't tell me this needs yet another custom function - it shouldn't be this difficult.
