In Chargebee, it is possible to pre-fill the custom fields in Checkout and Portal either with the drop-in script or by using Chargebee's API.


Via Drop-in Script

Once the custom field is created, all the parameters for the Customer can be passed using the setCustomer function. This information will be passed to checkout and will be prefilled - including the custom field.

You can use the SetCustomdata function to pass the Subscription level custom fields. To know more about the Checkout page script.

Please refer to the example shown under drop-in script customizations from here.
