Liquid Ajax API

Introduction to Liquid Ajax API

The Liquid Ajax API is a powerful tool that allows developers to create seamless user experiences by updating Shopify carts asynchronously. This means that changes to the cart can be made without requiring a page reload, enhancing the overall shopping experience.

By leveraging the Liquid Ajax API, you can perform various cart operations such as adding, updating, and removing items dynamically. This tutorial will guide you through the basics of using the Liquid Ajax API with practical examples.

Setting Up the Liquid Ajax API

To get started with the Liquid Ajax API, ensure your Shopify theme supports AJAX cart updates. Most modern themes have this capability built-in, but you may need to customize your theme to tailor it to your specific needs. Below is a basic setup to enable AJAX in your Shopify store.

Adding Items to Cart

The example above shows how to add a product to the cart using AJAX. The script listens for a click event on a button with the class .add-to-cart-button. When clicked, it prevents the default form submission and sends an AJAX POST request to /cart/add.js with the product ID and quantity.

The success callback function logs the response to the console, which includes details of the cart after the item is added.

Updating Cart Items

Updating cart items with AJAX is similar to adding them. You can modify the quantity of items in the cart by sending a POST request to /cart/change.js. Here’s an example:

Removing Items from Cart

To remove an item from the cart, set its quantity to zero using the same /cart/change.js endpoint. Here is an example to remove an item:
