## Confirm a Bancontact payment `stripe.confirmBancontactPayment(clientSecret: string, data?: object, options?: object)` Use `stripe.confirmBancontactPayment` in the [Bancontact Payments with Payment Methods](https://docs.stripe.com/payments/bancontact/accept-a-payment.md) flow when the customer submits your payment form. When called, it will confirm the `PaymentIntent` 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`. 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 needing to provide any additional data.
