Lightbox/Embedded Checkout

❗️
Deprecated
Lightbox/Embedded Checkout is no longer supported for new merchants and will be removed entirely in a future update.

Default Checkout

By default, customers who choose Zip at checkout are automatically redirected to Zip.

Lightbox Checkout

The lightbox checkout allows a more seamless experience at the checkout stage. Rather than a customer being redirected to Zip, it allows the Zip checkout process to be loaded in a lightbox within the merchant site.

📘
NB: Mobile devices are not supported for this experience - the lightbox code will detect the device used and redirect users who are on a mobile device.

Script

There are 2 options to load the script onto the page:

Adding a <script> element to their checkout page <head>

<head>
   <script async src="https://zip.co/nz/customer/assets/sandbox/partpay-sandbox-v1.js"></script>
</head>

Dynamically add the script element when the checkout button has been clicked

function appendSandboxScript() {
    var el = document.createElement("script");
    el.setAttribute("src", "https://zip.co/nz/customer/assets/sandbox/partpay-sandbox-v1.js");
    document.getElementsByTagName("head")[0].appendChild(el);
}

Use

Create an order via POST Create Order endpoint
The response returns a token to be used with the checkout process
When the customer clicks the checkout button, activate the Zip checkout with the Zip javascript object:

// Initiate Zip checkout
Zip.checkout({
    orderToken: token, // <--- token is the returned when creating an order.
    success: function () {
        // TODO: Handle a successful checkout.
        alert("Success");
    },
    cancel: function () {
        // TODO: Handle a cancelled checkout.
        alert("Cancelled");
    }
});

Embedded Checkout

The embedded checkout allows the Zip checkout to be hosted within an iframe on the merchant's website, rather than being redirected to Zip. This is a similar concept to the lightbox checkout.

Use

Create an order via POST Create Order endpoint
The response returns a token to be used with the checkout process
Append &embedded=true to the redirectUrl property and set the src attribute of the iframe to the URL

Example iframe element:

<iframe src="https://checkout.partpay.co.nz?token=ae59b28b-81dc-40de-b51a-e915ed87b381&embedded=true" style="width:600px;height:700px"></iframe>

Detecting Checkout End

The child iFrame will post a message to the parent indicating success or failure via the following messages:

zip-checkout-order-success
zip-checkout-close-window

Mobile Checkout

The Zip NZ Checkout flow can also be rendered within a Mobile Webview i.e. for iOS and for Android. This is particularly useful for displaying the checkout within a native merchant-based application.

Use

Create an order via POST Create Order endpoint (server-side)
The response returns a redirectUrl that can be provided to the mobile application (server-side)
Mobile application can render the redirectUrl in a webview to prompt the user to checkout via Zip (client-side)
Mobile application inspects redirects to determine the eventual status of the order (client-side)

Below are some open-source examples on how to determine the status of the order. Simply provide your test merchant details to proceed with the example

iOS / Android

📘
Important Security Note: Calling Zip / Login APIs within a mobile app is discouraged. In reality, your app must call your own E-Commerce Platform API to create the orders and provide Zip NZ checkout URLs for the web view.

We completely discourage the storage of any Zip NZ credentials in a client app. We also completely discourage direct access to the Zip NZ Bearer Token in a client app.
