Liquid Ajax API

Introduction to Liquid Ajax API

The Liquid Ajax API is a powerful tool for developers working with Shopify. It allows for asynchronous updates to the cart without the need to refresh the page, providing a seamless and efficient shopping experience for users. This capability is especially useful for modern e-commerce sites where user experience is critical.

How Liquid Ajax API Works

The Liquid Ajax API leverages JavaScript to make asynchronous HTTP requests to Shopify's servers. These requests are used to update the shopping cart dynamically. By utilizing this API, you can enhance the functionality of your Shopify store by adding items to the cart, removing items, or updating item quantities without a full page reload.

Basic Operations with Liquid Ajax API

Using the Liquid Ajax API, you can perform several basic operations. Here are some examples:

• Add to Cart: Add products to the cart asynchronously.
• Update Cart: Change quantities of items already in the cart.
• Remove from Cart: Remove items from the cart without reloading the page.

Adding Items to the Cart

To add an item to the cart using the Liquid Ajax API, you'll need to make a POST request to the '/cart/add.js' endpoint. This request should include the variant ID and quantity of the item you wish to add.

Updating Item Quantities

To update the quantity of an item in the cart, you can use the '/cart/change.js' endpoint. This request requires the line item ID and the new quantity.

Removing Items from the Cart

To remove an item from the cart, set the quantity to zero using the '/cart/change.js' endpoint. This effectively removes the item without needing a separate endpoint.

Error Handling in Ajax Requests

When working with Ajax requests, it's important to implement error handling to ensure a smooth user experience. You can use the catch method to handle any errors that may occur during the fetch process.
