I'm aware of the various prefill options for cookied website visitor, but specifically asking about url parameters. With most form tools, I can easily grab the form Id by inspecting the page, then use a url parameter to set a value in that field when the pages loads.
Something like: mywebsite.com/contact?msdyncrm_code-12345=google-ad > passes the value /google-ad/ into a hidden msdyncrm_code field, which then writes to the database. It doesn't appear to work, even with a non-hidden field. It just isn't populating.
Am I missing something or is this functionality not supported in marketing forms? Or maybe Outbound but not Real Time?
This scenario is supported in real-time marketing forms. You can use JavaScript to parse the value from URL and update a hidden field in the form with that value. Important: Make sure you place your JavaScript into the <head> section. Otherwise it will be removed. Also make sure that the JavaScript toggle is enabled in Settings->Feature switches:
We have the exact same requirement. This would allow us to pass the GUID of an existing Lead in order to let the customer update existing fields of their Lead.
Did you find a solution to this?
