Pay by Bank

Overview

Pay by Bank is a customer-facing payment method that lets a payer authorize a direct account-to-account payment from a bank account, commonly through open banking technology. Pay by Bank is often used as a commercial label for open banking payments. A regulated provider connects the merchant to participating banks and returns payment status information.

The customer selects a bank, is redirected or handed off to the bank’s authenticated environment, reviews prefilled payment details, and approves the transfer. The merchant integration should protect redirect state, preserve the order reference, verify callbacks, map bank statuses, and reconcile the transfer with the order and account records. These records support Payment Status and let an operator reproduce the result from authoritative evidence rather than relying on a dashboard snapshot or a provider’s latest status alone. Refund and dispute processes may differ from card payments and across jurisdictions.

For merchants, developers, finance teams, and payment operators, a well-designed implementation means that customer authorization, provider processing, payment status, and final financial evidence remain distinct but traceable throughout the payment journey.

Fraudulent redirection, beneficiary manipulation, customer abandonment, bank downtime, and premature fulfillment are key risks. Important failure modes include duplicate or delayed events, wrong destinations or currencies, stale instructions, unavailable providers, unsupported retries, and customer-facing status that differs from authoritative records.

The final control should feed Payment Reconciliation , preserve the original evidence, and document any correction, override, or manual action. Controls should validate inputs server-side, authenticate external events, make irreversible actions idempotent, and reconcile provider, network, settlement, and ledger evidence. For Pay by Bank, this point supports the definition’s focus on customer-facing payment method that lets a payer authorize a direct account-to-account payment from a bank account, commonly through.
