# paymentAuthorizationController(_:didAuthorizePayment:handler:)

Tells the delegate that the user authorized the payment request, and asks for a result.

```
@MainActor optional func paymentAuthorizationController(_ controller: PKPaymentAuthorizationController, didAuthorizePayment payment: PKPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void)
```

## Parameters

`controller`

The payment authorization controller.

`payment`

The authorized payment. This object contains the payment token you need to submit to your payment processor, as well as the billing and shipping information required by the payment request.

`completion`

The completion handler to call with the result of authorizing the payment.

## Discussion

The system calls this method after the payment request is authorized. You submit the payment information to your payment processor to authorize the transaction, and then call the handler.
