## Confirm a PayPal payment

Use `stripe.confirmPayPalPayment` in the [PayPal Payments with Payment Methods](/payments/paypal/accept-a-payment.md) flow when the customer submits your payment form.
When called, it will confirm the `PaymentIntent`, 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`.

> Note that `stripe.confirmPayPalPayment` 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.confirmPayPalPayment` will trigger a redirect when successful.
If there is an error, 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.confirmPayPalPayment(...)`

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

- `data` (object)
  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` (string | object)
    The `id` of an existing [PaymentMethod](/api/payment_methods.md).
See the use case sections below for details.

  - `return_url` (string)
    The url your customer will be directed to after they complete authentication.
Required for new PayPal payment methods, but not required when using a previously set up PayPal payment method (via SetupIntent or a PaymentIntent with `setup_future_usage`).

### Use case: with a new PaymentMethod

You can confirm the `PaymentIntent` using `stripe.confirmPayPalPayment` without
passing in any additional data. This will automatically create and attach a new
`PaymentMethod`.

### Data argument properties

- `return_url` (string)
  The url your customer will be directed to after they complete authentication.
Required for new PayPal payment methods, but not required when using a previously set up PayPal payment method (via SetupIntent or a PaymentIntent with `setup_future_usage`).

### Confirm with a new PaymentMethod

```js
stripe
  .confirmPayPalPayment('{PAYMENT_INTENT_CLIENT_SECRET}', {
    // Return URL where the customer should be redirected after
    // the authorization.
    return_url: "https://example.com/checkout/complete",
  })
  .then(function(result) {
    if (result.error) {
      // Inform the customer that there was an error.
    }
  });
```

```es_next
const {error} = await stripe.confirmPayPalPayment(
  '{PAYMENT_INTENT_CLIENT_SECRET}',
  {
    // Return URL where the customer should be redirected after
    // the authorization.
    return_url: "https://example.com/checkout/complete",
  },
);
```

### Use case: with an existing payment method

Use `stripe.confirmPayPalPayment` with an existing `PaymentMethod` by passing its `id` to `payment_method`.
The `PaymentMethod` will be used to confirm the `PaymentIntent`.

### Data argument properties

- `payment_method` (string) **required**
  The `id` of an existing `PaymentMethod`.

- `return_url` (string)
  The url your customer will be directed to after they complete authentication.

### Confirm with existing payment method

```js
stripe
  .confirmPayPalPayment('{PAYMENT_INTENT_CLIENT_SECRET}', {
    payment_method: '{PAYMENT_METHOD_ID}',
    // Return URL where the customer should be redirected after the authorization.
    return_url: "https://example.com/checkout/complete",
  })
  .then(function(result) {
    if (result.error) {
      // Inform the customer that there was an error.
    }
  });
```

```es_next
const {error} = await stripe.confirmPayPalPayment(
  '{PAYMENT_INTENT_CLIENT_SECRET}',
  {
    payment_method: '{PAYMENT_METHOD_ID}',
    // Return URL where the customer should be redirected after the authorization.
    return_url: "https://example.com/checkout/complete",
  },
);
```

### Use case: with an attached PaymentMethod

If you have already attached a `PaymentMethod` to this `PaymentIntent`, then you can confirm the `PaymentIntent` using `stripe.confirmPayPalPayment` without passing in any additional data.

### Confirm with an attached PaymentMethod

```js
stripe
  .confirmPayPalPayment('{PAYMENT_INTENT_CLIENT_SECRET}', {
    // Return URL where the customer should be redirected after
    // the authorization.
    return_url: "https://example.com/checkout/complete",
  })
  .then(function(result) {
    if (result.error) {
      // Inform the customer that there was an error.
    }
  });
```

```es_next
const {paymentIntent, error} = await stripe.confirmPayPalPayment(
  '{PAYMENT_INTENT_CLIENT_SECRET}',
  {
    // Return URL where the customer should be redirected after
    // the authorization.
