Display Seamless View

Among the operations in the POST paymentOrders response, you will find the view-checkout. This is the one you need to display the purchase module.

}

Load The Seamless View

Embed the href in a <script> element. That script will then load the Seamless View.

To load the Checkout from the JavaScript URL obtained in the backend API response, it needs to be set as a script element’s src attribute. You can cause a page reload and do this with static HTML, or you can avoid the page refresh by invoking the POST to create the payment order through Ajax, and then create the script element with JavaScript. The HTML code will be unchanged in this example.

    var operation = response.operations.find(function (o) {

    script.setAttribute('src', operation.href);
    script.onload = function () {
        // When the 'view-checkout' script is loaded, we can initialize the
        // Payment Menu inside 'checkout-container'.
        payex.hostedView.checkout({
            container: {
                checkout: "checkout-container"
            },
            culture: 'nb-No',
        }).open();
    };
    // Append the Checkout script to the <head>
    var head = document.getElementsByTagName('head')[0];
    head.appendChild(script);

// Like before, you should replace the address here with
// your own endpoint.

How Seamless View Looks

The payment menu should appear with the payer information displayed above the menu. The payer can select their preferred payment method and pay.

Once the payer has completed the purchase, you can perform a GET towards the paymentOrders resource to see the purchase state.

Events

When integrating Seamless View, we strongly recommend that you implement the onPaid event, which will give you the best setup. Even with this implemented, you need to check the payment status towards our APIs, as the payer can make changes in the browser at any time.

You can read more about the different Seamless View Events available in the feature section.

You are now ready to capture the funds. Follow the link below to read more about capture and the other options you have after the purchase.
