• {{ campaign.id }} — The ID of the display associated with the signup.
• {{ signup.coupon_code }} — The coupon code that was shown to the contact who just signed up. This variable is only populated when the signup produced a coupon code.
• {{ contact.custom_fields.sms_opt_in }} — The SMS opt-in value submitted by the contact.
• {{ contact.custom_fields.phone }} — The phone number submitted by the contact. The personalization variable menu inserts this variable. Existing snippets using {{ contact.phone_number }} remain supported as a backward-compatible alias.

​

Variable requirements + limitations

• Conversion JS variables are only populated with data collected during the current signup event.
• A custom field variable must use the field’s exact identifier. You can select available fields from the personalization variable menu in the custom conversion JS editor.
• The full {{ contact.custom_fields }} object cannot be used.
