Understanding the payment methods
Cards means card payments through the provider. Network tokens can support Apple Pay and Google Pay. Wallet availability and setup vary by provider; some hosted wallet integrations require Shuttle to enable a beta feature.
ACH, SEPA, Bacs, BECS, BECS NZ, PAD, Autogiro and Betalingsservice are direct debit schemes. Bank transfers, open banking, local payment methods and pay-later options are listed separately where supported.
For connection instructions, supported countries and provider-specific requirements, see the individual provider pages in Shuttle’s documentation.
