## Confirm SEPA Debit setup

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

Use `stripe.confirmSepaDebitSetup` in the [SEPA Direct Debit with Setup Intents](https://docs.stripe.com/payments/sepa-debit-setup-intents.md) flow when the customer submits your payment form.
When called, it will confirm the `SetupIntent` 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/sepa-debit-setup-intents.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.confirmSepaDebitSetup` 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.
