This implementation does not require any backend integration. With a few lines of HTML and/or JavaScript, you can accept installment payments in their checkout in less than an hour!

The Virtual Checkout integration is based on three components.

1. A reference to our CDN hosted JavaScript library.
2. A Quadpay-button element or HTML DOM element
3. JavaScript code to attach one or many callback functionality(s) and customize the payment flow.

There are two different ways to implement the Virtual Checkout (step 2 above). You can either utilize a Zip-branded button element or a custom DOM element. The Quadpay-button serves as a turnkey solution that is easiest to work with. You may choose to work with a custom DOM element for a more customized integration. Both are fully supported and our button is actually built on top of the same library.
