Checkout V1

Table of contents

Checkout version 1 requires you to manage the loading of a checkout URL yourself and provide it to the SDK. This version of checkout only supports standard mode and completes on receiving a redirect.

The Web Login is a UIViewController that can be presented modally over the view controller of your choosing.

When creating a checkout token, both redirectConfirmUrl and redirectCancelUrl must be set. Failing to do so will cause undefined behavior. The SDK’s example merchant server sets the parameters here. See more by checking the api reference.

Swift (UIKit)

import Afterpay
import UIKit

final class CheckoutViewController: UIViewController {
  // ...
  @objc func didTapPayWithAfterpay() {
    /**
     * `presentCheckoutModally` can take a `shouldLoadRedirectUrls` which is
     * a boolean for whether the redirect urls set when generating
     * the checkout url should load. Default and recommended value is false
     */
    Afterpay.presentCheckoutModally(over: self, loading: self.checkoutUrl) { result in
      switch result {
      case .success(let token):
        // Handle successful Afterpay checkout
      case .cancelled(let reason):
        // Handle checkout cancellation
      }
    }
  }
}

Objective-C (UIKit)

@implementation ViewController

  void (^completion)(APCheckoutResult *) = ^(APCheckoutResult *result) {

    if ([result isKindOfClass:[APCheckoutResultSuccess class]]) {
      // Handle success with [(APCheckoutResultSuccess *)result token]
    } else {
      // Handle cancellation with [(APCheckoutResultCancelled *)result reason]
