Items you will need:

The Zip iOS SDK

  • Our SDK is currently public, simply add the following to your Podfile and run pod install
    pod 'QuadPaySDK'

How to start a Zip checkout in your iOS App

Initialize the Zip SDK

Your 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".

For enablement in other markets, set locale with your locale variable ("MX" for Mexico).

Typically this is done in didFinishLaunchingWithOptions:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    [[Zip sharedInstance] initialize:@"<merchant_id>"
    return YES;

Start the Zip Checkout

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

UINavigationController *navController = [
  QuadPay startCheckout
    customerEmail:@"[email protected]"
    customerAddressLine1:@"123 Main St."
    customerAddressLine2:@"10th Floor"
    customerCity:@"New York"
[self presentViewController:navController animated:YES completion:nil];

Implement the QPCheckoutDelegate functions

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

Checkout Success

This function returns an order id you may use to confirm an order has been created.

- (void) checkoutSuccessful:(QuadPayCheckoutViewController*)viewController orderId:(NSString*)orderId
    // The user has completed checkout -- the order id must be used to confirm the transaction from the backend
    NSLog(@"Zip checkout succeeded with order id: %@", orderId);

Checkout Cancelled

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

- (void)checkoutCancelled:(QuadPayCheckoutViewController*)viewController reason:(NSString *)reason
    // The Zip checkout session has been cancelled
    NSLog(@"Zip checkout cancelled, reason: %@", reason);

Confirming your Zip orders

As soon as your customer has completed checkout an order id will be issued. To finalize the transaction this order id must be submitted to Zip's confirmation endpoint. The order id will last for 24 hours under default settings to be confirmed.

The timing of your shipping can be any time after you have confirmed the order. When submitting the order id you will have a chance to finalize the order amount.

Post the Order ID to the confirmation endpoint
See for information regarding signing requests


curl -X post{orderId}/confirm
  -H 'content-type: application/json' 
  -H 'X-QP-Signature: [signature]'
  -d '{
    "orderId": [orderId],
    "totalOrderAmount": <number>, (optional)
    "taxAmount": <number>, (optional),
    "shippingAmount": <number>, (optional)

An Order Id will be returned:

  "orderId": [order id]

Service after confirmation

Once the order has been confirmed and an order id has been received the user should be guided to a success page.

This order id can also be used to update the order using our normal orders integration API at
