Not sure if I'm asking this right...
I need to pass a few lead IDs at the form submission event but am unable to add hidden fields to the form. Is it possible to update the lead entity in CRM (ZOHO) right after form submission, via the POST method, using only JavaScript? (I have access to google tag manager and nothing else)
This is the scenario: lead is submitted via a web form which triggers custom JS Google tag manager tag use some kind of webhook to update newly created lead in CRM.
Is this possible or do I need to provide better info?
Thank you very much
