## Confirm a BECS Debit payment

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

Use `stripe.confirmAuBecsDebitSetup` in the [BECS Direct Debit Payments](https://docs.stripe.com/payments/au-becs-debit.md) flow when the customer submits your payment form. When called, it will confirm the [SetupIntent](https://docs.stripe.com/api/setup_intents.md) with `data` you provide. 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/au-becs-debit.md) for more details.

When you confirm a `SetupIntent`, it needs to have an attached [PaymentMethod](https://docs.stripe.com/api/payment_methods.md). In addition to confirming the `SetupIntent`, this method can automatically create and attach a new `PaymentMethod` for you. It can also be called with an existing `PaymentMethod`, or if you have already attached a `PaymentMethod` you can call this method without needing to provide any additional data. These use cases are detailed in the sections that follow.

> Note that `stripe.confirmAuBecsDebitSetup` may take several seconds to complete.
> During that time, you should disable your form from being resubmitted and show a waiting indicator like a spinner.
> If you receive an error result, you should be sure to show that error to the customer, re-enable the form, and hide the waiting indicator.

* `clientSecret` - The [client secret](https://docs.stripe.com/api/setup_intents/object.md#setup_intent_object-client_secret) of the `SetupIntent`.
