## Confirm a TWINT payment

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

Use `stripe.confirmTwintPayment` in the TWINT payment method creation flow when the customer submits your payment form.
When you call the method, it confirms the [PaymentIntent](https://docs.stripe.com/api/payment_intents.md) with the `data` you provide, and automatically redirects the customer to authorize the transaction.
Once authorization is complete, the customer is 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've already attached a `return_url` and 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.confirmTwintPayment` might 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, show that error to the customer, re-enable the form, and hide the waiting indicator.

  The [client secret](https://docs.stripe.com/api/payment_intents/object.md#payment_intent_object-client_secret) of the `PaymentIntent`.
