## Confirm a Sofort payment `stripe.confirmSofortPayment(clientSecret: string, data?: object, options?: object)` Use `stripe.confirmSofortPayment` in the [Set up future payments](https://docs.stripe.com/payments/sofort/set-up-payment.md) flow to use SOFORT bank details to set up a SEPA Direct Debit payment method for future payments. When called, it will confirm a `SetupIntent` with `data` you provide, and it will automatically redirect the customer to authorize the transaction. Once authorization is complete, the customer will be redirected back to your specified `return_url`. 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/sofort/set-up-payment.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.confirmSofortSetup` 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`. - `data` Data to be sent with the request. Refer to the [Setup Intents API](https://docs.stripe.com/api/setup_intents/confirm.md) for a full list of parameters. - `payment_method` The `id` of an existing PaymentMethod or an object of collected data. See use cases below for details. - `return_url` The url your customer will be directed to after they complete authentication. - `options` An options object to control the behavior of this method. - `handleActions` Set
