Using Extra Fields in Liquid

You can optionally collect additional details from your customers by creating Extra Fields in Checkout settings. For example you can create a birthday field, which you can then use in Liquid as {{extra_field.birthday}}.

How it works

If you add an "Extra Field" field, "Pet name" for example, it can be translated to {{extra_field.pet_name}}. This feature can be accessed on the Firmhouse portal via the "Checkout" menu > "Extra fields and Validations" submenu on the left. Here you can Create, Edit and Delete an extra field.
