## Confirm a BLIK payment

Use `stripe.confirmBlikPayment` in the [BLIK Payments with Payment Methods](/payments/blik.md) flow when the customer submits your payment form.
When called, it will confirm the `PaymentIntent` with `data` you provide, and it will automatically prompt the customer to authorize the transaction.

> Note that `stripe.confirmBlikPayment` 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.

By default, `stripe.confirmBlikPayment` will only return when the payment has succeeded or failed.
If there is an error, or when handling next actions manually by using the `handleActions: false` option, it will return a `Promise` which resolves with a `result` object.
This object has either:

* `result.paymentIntent`: the successful [PaymentIntent](/api/payment_intents).
* `result.error`: an error.
  Refer to the [API reference](/api/errors) for all possible errors.

**Syntax:** `stripe.confirmBlikPayment(...)`

- `clientSecret` (string) **required**
  The [client secret](/api/payment_intents/object.md#payment_intent_object-client_secret) of the `PaymentIntent`.

- `data` (object) **required**
  Data to be sent with the request.
Refer to the [Payment Intents API](/api/payment_intents/confirm.md) for a full list of parameters.

  - `payment_method_options` (object) **required**
    An object that contains transaction specific data.

    - `code` (string) **required**
      Your customer's 6-digit BLIK code.

  - `payment_method` (object)
    Use this parameter to supply additional data relevant to the transaction, such as billing details.

    - `billing_details` (object)
      The [billing details](/api/payment_methods/create.md#create_payment_method-billing_details) associated with the transaction.

- `options` (object)
  An options object to control the behavior of this method.

  - `handleActions` (boolean)
    Set this to `false` if you want to manually determine if the confirmation has succeeded or failed.
