## Confirm a Konbini payment

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

Use `stripe.confirmKonbiniPayment` in the [Konbini](https://docs.stripe.com/payments/konbini.md) payment flow when the customer submits your payment form. When called, it will confirm the [PaymentIntent](https://docs.stripe.com/api/payment_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/konbini/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). 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. These use cases are detailed in the sections that follow.

> Note that `stripe.confirmKonbiniPayment` 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.
