## Confirm a Pay by Bank payment

`stripe.confirmPayByBankPayment(clientSecret: string, data?: object, options?: object)`

Use `stripe.confirmPayByBankPayment` in the [Pay by Bank Payments with Payment Methods](https://docs.stripe.com/payments/pay-by-bank.md) flow when the customer submits your payment form.
When called, it confirms the `PaymentIntent` with `data` you provide. It then automatically redirects the customer to authorize the transaction.
After authorization is complete, the customer is redirected back to your specified `return_url`.

When you confirm a `PaymentIntent`, it needs to have an attached [PaymentMethod](https://docs.stripe.com/api/payment_methods.md).
In addition to confirming the `PaymentIntent`, this method can automatically create and attach a new `PaymentMethod` for you.
If you have already attached a `PaymentMethod` you can call this method without providing any additional data.
These use cases are detailed in the sections that follow.

> Be aware that `stripe.confirmPayByBankPayment` might take several seconds to complete.
> During that time, disable your form from being resubmitted and show a waiting indicator like a spinner.
> If you receive an error result, show that error to the customer, re-enable the form, and hide the waiting indicator.
