## Confirm a Konbini payment

Use `stripe.confirmKonbiniPayment` in the [Konbini](/payments/konbini.md) payment flow when the customer submits your payment form.
When called, it will confirm the [PaymentIntent](/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](/payments/konbini/accept-a-payment.md) for more details.

When you confirm a `PaymentIntent`, it needs to have an attached [PaymentMethod](/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.

`stripe.confirmKonbiniPayment` will return a `Promise` which resolves with a result object.
This object has either:

* `result.paymentIntent`: the successful PaymentIntent.
* `result.error`: an error.
  Refer to the API reference for all possible errors.
