If you’ve already collected some key info in a previous step like a form, and are then sending customers to a Paythen plan payment page, to ensure key data like the name, email and any custom fields remain consistent, you can now freeze them so customers can see them on the payment page but can’t change them. This only works with fields you are pre-filling. This helps ensure your data remains consistent between different systems and avoids accidental changes.
To freeze pre-filled fields, you just need to add another url parameter at the end of the plan or template url like this: freeze=field1,field2,etc. You can see detailed instructions on any plan or template summary page in your Paythen dashboard.
