I have an automation that sends out a link to a Cognito Form when a new deal is created and I then use Zapier to update the deal to a new stage when the form is returned.
The Zap searches for the correct deal by email address of the contact.
The problem I have is there could be two deals for the same contact, in which case I need Zapier to be able to distinguish between the deals so that it updates the correct one.
When i create the link to the Cognito Form I can pass variables to the form to prepopulate fields. EG I can use the personalization variables to poplualte the Organization field using %Organization%
Is there a unique variable I can send to the form so that Zapier can distinguish specific forms for the same contact
