## Confirm an FPX payment

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

Use `stripe.confirmFpxPayment` in the [FPX payment method creation](https://docs.stripe.com/stripe-js/elements/fpx-bank.md) 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, 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. These use cases are detailed in the sections that follow.

> Note that `stripe.confirmFpxPayment` 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.

* `clientSecret` - The [client secret](https://docs.stripe.com/api/payment_intents/object.md#payment_intent_object-client_secret) of the `PaymentIntent`.
* `data` - Data to be sent with the request. Refer to the [Payment Intents API](https://docs.stripe.com/api/payment_intents/confirm.md) for a full list of parameters.
    * `payment_method` - Either the `id` of an existing [PaymentMethod](https://docs.stripe.com/api/payment_methods.md), or an object containing data to create a `PaymentMethod` with. See the use case sections below for details.
    * `return_url` - The url your customer will be directed to after they complete authentication.
* `options` - An options object to control the behavior of this method.
    * `handleActions` - Set this to `false` if you want to [manually handle the authorization redirect](https://docs.stripe.com/payments/fpx/accept-a-payment.md#handle-redirect). Default is `true`.

### with payment data from an Element

Data argument properties

* `payment_method` - Pass an `object` to confirm using data collected by an `fpxBank` Element.
