How to start a Zip checkout in your iOS App

Initialize the Zip SDK

our merchant id will be provided by your Zip account manager.
Please make sure you are using the production merchantId with environment "production" and the sandbox merchantId with environment "sandbox".

Typically this is done in didFinishLaunchingWithOptions:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[QuadPay sharedInstance] initialize:@"<merchant_id>"
      environment:@"production"
      locale:@"US"
    ];
    return YES;
}

Start the Zip Checkout

Once presented the customer will be shown the Zip checkout flow.

UINavigationController *navController = [
  QuadPay startVirtualCheckout
    delegate:self
    amount:@"123.45"
    merchantReference"@"unique-order-id"
    customerFirstName@"Zip"
    customerLastName:@"Customer"
    customerEmail:@"[email protected]"
    customerPhoneNumber:@"+15555555555"
    customerAddressLine1:@"123 Main St."
    customerAddressLine2:@"10th Floor"
    customerCity:@"New York"
    customerState:@"NY"
    customerPostalCode:@"10003"
    customerCountry:@"US"
    merchantFeeForPaymentPlan: "0"
];
[self presentViewController:navController animated:YES completion:nil];

Implement the QPVirtualCheckoutDelegate functions

These functions give your application information regarding the result of the Zip checkout flow.

Checkout Success

This function returns a token you may exchange to confirm an order has been created.

- (void)checkoutSuccessful:(QuadPayCard *)card cardholder:(QuadPayCardHolder *)cardholder orderId:(nonnull NSString *)orderId 
{
    // The user has completed checkout
    // A virtual card has been returned
    // Pass the details in card and cardholder into your standard payment processor
    NSLog(@"%@", [NSString stringWithFormat:@"Card: %@ Issued for %@", [card toString], [cardholder toString], [orderId]]);
}

For card and cardholder types please see https://developers.zip.co/v9-US/docs/object-model#card.

Checkout Cancelled

This function is called when the user cancels the Zip process or is declined.

- (void)checkoutCancelled:(NSString *)reason
{
    // The Zip checkout session has been cancelled
    NSLog(@"%@", [NSString stringWithFormat:@"User cancelled QuadPay checkout with reason %@", reason]);
}

Finishing the Zip order

Once you have received a virtual card number in a success delegate you may authorize and capture it up to the value provided at the beginning of checkout. The card that is issued is a standard Visa card and all authorize/capture/refund functionality will work as expected.
