How can I pre-fill the form?

You can pre-fill the form of a payment link by passing values via the query string in the URL.

For payment links with type one-off, subscription, one-off direct debit or mandate, the following parameters are possible:

  • first_name
  • last_name
  • name
  • email
  • iban (only for links with as type "one-off direct debit")
  • amount (only for links with an open amount)

You can place these parameters behind the payment link URL

?name=John Doe&

The full URL will then something be like: Doe&

Order payment links

Shipping costs do not need to be specified as they are automatically added to the order.

It is also possible to skip the first step directly, so that the customer can enter his/her data immediately. You do this by specifying an additional parameter:


The full url then looks like this:
