## Confirm a Canadian pre-authorized debit payment

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

Use `stripe.confirmAcssDebitPayment` in the [Accept a payment](https://docs.stripe.com/payments/accept-a-payment.md) flow for the [Canadian pre-authorized debit](https://docs.stripe.com/payments/acss-debit.md) payment method when the customer submits your payment form.
When called, it will automatically load an on-page modal UI to collect bank account details and verification, accept a hosted mandate agreement, and confirm the [PaymentIntent](https://docs.stripe.com/api/payment_intents.md) when the user submits the form.
Note that there are some additional requirements to this flow that are not covered in this reference.
Refer to our [integration guide](https://docs.stripe.com/payments/acss-debit/accept-a-payment.md) for more details.

When you confirm a `PaymentIntent`, it needs to have an attached [PaymentMethod](https://docs.stripe.com/api/payment_methods.md).
`stripe.confirmAcssDebitPayment` automatically creates a new `PaymentMethod` for you when your customer completes the modal UI.
It can also be called with an existing `PaymentMethod`, which will load the modal UI to collect a new mandate agreement.
These use cases are detailed in the sections that follow.

> Note that `stripe.confirmAcssDebitPayment` may 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 it to the customer, re-enable the form, and hide the waiting indicator.
