public class STPPaymentHandler : NSObject, SFSafariViewControllerDelegate, STPURLCallbackListener

STPPaymentHandler is a utility class that confirms PaymentIntents/SetupIntents and handles any authentication required, such as 3DS1/3DS2 for Strong Customer Authentication. It can present authentication UI on top of your app or redirect users out of your app (to e.g. their banking app).

  • When this flag is enabled, STPPaymentHandler will confirm certain PaymentMethods using Safari instead of SFSafariViewController. If you’d like to use this in your own testing or Continuous Integration platform, please see the IntegrationTester app for usage examples.

    Note: This flag is only intended for development, and only impacts payments made with testmode keys. Setting this to true with a livemode key will fail.

  • Confirms the PaymentIntent with the provided parameters and handles any nextAction required to authenticate the PaymentIntent. Call this method if you are using automatic confirmation. - seealso: https://stripe.com/docs/payments/payment-intents/ios

    Declaration

    Swift

    @objc(confirmPayment:withAuthenticationContext:completion:)
public func confirmPayment(
    _ paymentParams: STPPaymentIntentParams,
    with authenticationContext: STPAuthenticationContext,
    completion: @escaping STPPaymentHandlerActionPaymentIntentCompletionBlock
)

    Parameters

    paymentParams

    The params used to confirm the PaymentIntent. Note that this method overrides the value of paymentParams.useStripeSDK to @YES.
    authenticationContext

    The authentication context used to authenticate the payment.
    completion

    The completion block. If the status returned is STPPaymentHandlerActionStatusSucceeded, the PaymentIntent status is not necessarily STPPaymentIntentStatusSucceeded (e.g. some bank payment methods take days before the PaymentIntent succeeds).

  • Handles any nextAction required to authenticate the PaymentIntent. Call this method if you are using manual confirmation. - seealso: https://stripe.com/docs/payments/payment-intents/ios

    Declaration

    Swift

    @objc(handleNextActionForPayment:withAuthenticationContext:returnURL:completion:)
public func handleNextAction(
    forPayment paymentIntentClientSecret: String,
    with authenticationContext: STPAuthenticationContext,
    returnURL: String?,
    completion: @escaping STPPaymentHandlerActionPaymentIntentCompletionBlock
)

    Parameters

    paymentIntentClientSecret

    The client secret of the PaymentIntent to handle next actions for.
    authenticationContext

    The authentication context used to authenticate the payment.
    returnURL

    An optional URL to redirect your customer back to after they authenticate or cancel in a webview. This should match the returnURL you specified during PaymentIntent confirmation.
    completion

    The completion block. If the status returned is STPPaymentHandlerActionStatusSucceeded, the PaymentIntent status will always be either STPPaymentIntentStatusSucceeded, or STPPaymentIntentStatusRequiresConfirmation, or STPPaymentIntentStatusRequiresCapture if you are using manual capture. In the latter two cases, confirm or capture the PaymentIntent on your backend to complete the payment.
