## Confirm a GrabPay payment

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

Use `stripe.confirmGrabPayPayment` in the [GrabPay payments with Payment Methods](https://docs.stripe.com/payments/grabpay.md)
flow when the customer submits your payment form. When called, it will confirm the
[PaymentIntent](https://docs.stripe.com/api/payment_intents.md), and 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 `stripe.confirmGrabPayPayment` 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.
