Form based campaigns with CRM Lookup

Form based campaigns with CRM Lookup

Hello,

I am sending emails with a form link to my contacts via ZOHO CRM, to let them check and eventually update their details.
If they click on the form link, the form that pops-up is already prepopulated with their details stored in CRM. (Lookup field).
I would like to do the same with Marketing-Hub. But the form integration is only linking a form and not auto-filling existing fields.

Thanks for your help
