I am trying to design an integration with Zendesk, so that the deal owner in PD is notified if a support ticket is created, and the support rep gets information that the request is linked to an ongoing deal.

The problem I am facing with Zapier is that you can't find a deal based on contact person email (at least according to their support) as there is no Deal Person Email field.

Now, I could add the email as a custom field to the deal and look up that value, but I really don't want more custom fields...

Has anyone successfully integrated these two (or similar), and can share some experiences?
