## Collect bank account details for setup

Use `stripe.collectBankAccountForSetup` in the [Save bank details](/payments/ach-direct-debit/set-up-payment.md) flow for the [ACH Direct Debit](/payments/ach-direct-debit.md) payment method to collect the customer’s bank account in your payment form.
When called, it will automatically load an on-page modal UI to collect bank account details and verification, and attach the [PaymentMethod](/api/payment_methods.md) to the [SetupIntent](/api/setup_intents.md).

When the `stripe.collectBankAccountForSetup` completes successfully, it returns a SetupIntent.
If the customer provided their account, the SetupIntent is in the `requires_confirmation` state. If the customer closed the dialog without providing their account, the SetupIntent is in the `requires_payment_method` state.
Use [stripe.confirmUsBankAccountSetup](/js/setup_intents/confirm_us_bank_account_setup) to complete the process.
