      To generate an Atpay Button, follow these steps:
      Create a text file, e.g. data.txt, containing an email address and the associated credit card token separated by a comma. Enter multiple lines for multiple buttons:

      test1@example.com,TL1UwJFXVN7e4p6+0B5N8hy4qQyqeNxVllmC663MLcMupuAWXdHJ9g8PRAnlIh+AMZBgpaIrfWStZ5/3hYi6vCAV7q6+3M6LLqxk
