Privy supports the use of Liquid variables in your custom conversion JavaScript (JS). These variables allow you to inject information related to a signup event, including contact and display information, into your custom JS code. 

​
Supported variables

The following variables are supported in your conversion JS:
  • {{contact.email}} — The email address of the contact who just signed up.
  • {{contact.first_name}} — The first name of the contact who just signed up.
  • {{contact.last_name}} — The last name of the contact who just signed up.
  • {{signup.coupon_code}} — The coupon code that was shown to the contact who just signed up.
  • {{campaign.id}} — The ID of the display associated with the contact’s signup. 
  • {{contact.custom_fields.custom_name}} - The value associated with a custom field that was included in the display’s form.

​
Variable requirements + limitations

The following requirements and limitations apply to custom fields:
  • A custom field variable must exactly match the name of the field in the Privy form.
  • The {{contact.custom_fields}} variable cannot be used; only individual fields are supported.
  • The only contact data that will be available for Liquid variable rendering after a form is submitted is the data that was collected during the current signup event.

​
Include variables in your code

Liquid variables and their associated attribute values are included in your code by applying a specific format to the custom JavaScript snippet. Typical use cases include: ​If a user named “Joe Smith” with the email “joesmith@example.com” just signed up, the above code will print “Joe Smith (joesmith@example.com) just signed up!” to the console.

​
Redirect and pass a variable value

The above code will redirect the user after signing up and pass the display id as a URL parameter to the new page.
