Make sure to check out this article first in order to learn how to setup the Zendesk Sell integration and map your custom fields.
In order for Zendesk Sell to create deals, you'll need to enable the option via Zendesk Sell's integration settings - to access this screen, simply go to your project's integrations page and click the button "Manage Custom Fields" on Zendesk Sell.
All you need to do then is tick the box "Create deal in Zendesk Sell" on your integration settings screen. This will make it so that a new deal is created every time a new submission is generated. Deals are only available for contacts, and not for leads.
You will also have the following options when setting up Zendesk Sell deals in involve.me:
Deal title - Adds a title that is prefixed with the contact's name.
Deal value - You can add your own value, or you can leave this field empty if you want to use a calculator result instead.
Once you've set up the integration and the deal settings to your liking, you're all set.
