What is the Shopify Ajax API?

Shopify Ajax, often referred to as “Shopify AJAX Cart” or “Shopify Ajax API,” is a method used by developers to create a more seamless and interactive shopping experience on Shopify-powered e-commerce websites. 

AJAX (Asynchronous JavaScript and XML) is a set of web development techniques that allows web pages to update and display data dynamically without requiring a full page reload. In the context of Shopify, AJAX is used to add dynamic and interactive features to the shopping process. 

What is the Shopify Ajax API?

Shopify provides APIs and JavaScript libraries to enable developers to implement these features. By utilizing Shopify Ajax effectively, e-commerce businesses can create more appeal, thereby increasing sales and customer satisfaction.

The Benefits of Using the Shopify Ajax API

The Shopify Ajax API offers several benefits for e-commerce businesses and their customers. Here are some of the key advantages of incorporating the Shopify Ajax API into your online store:

  • Improved user experience: AJAX lets you update product information, cart contents, and other elements in real-time without requiring full page reloads. This creates a smoother and more interactive shopping experience.
  • Faster page load times: AJAX reduces the need for complete page refreshes, which can significantly improve page load times. Faster loading pages increase user satisfaction and positively impact SEO and conversion rates.
  • Enhanced Cart Functionality: AJAX enables the creation of dynamic and interactive shopping carts. Customers can easily view and edit cart contents without navigating to a separate page.
  • Quick product previews: You can implement quick product views and previews, allowing customers to access product details without leaving the current page.
  • Live Search and Filtering: AJAX-powered live search and filtering make it easier for customers to find the products they’re looking for quickly. As they type their search query or select filters, relevant results are displayed in real-time.
  • Seamless product loading: Instead of traditional pagination, you can use AJAX to load more products as customers scroll down a collection page. This eliminates the need for manual navigation between pages and keeps customers engaged.
  • Real-time inventory and pricing updates: AJAX can provide real-time updates on product availability, prices, and stock levels. This ensures customers have continuous access to the latest information.
  • Add-to-cart animations: Adding smooth animations when items are added to the cart not only enhances the visual appeal of your store but also provides immediate feedback to customers that their action was successful.
  • Customization and personalization: With the flexibility of AJAX, you can tailor and personalize the shopping experience to better align with your brand and customer preferences.
  • Increased conversions and sales: A more user-friendly and interactive shopping experience often increases conversions and sales. Customers are more likely to complete their purchases when the process is seamless and engaging.
  • Competitive advantage: Implementing AJAX on your Shopify store provides a more modern and efficient shopping experience, setting you apart from competitors with static and less engaging websites.
  • Mobile friendliness: AJAX can also improve the mobile shopping experience, which is crucial as mobile commerce grows. Smooth and efficient interactions on mobile devices can lead to higher conversion rates.

Step-by-Step Guide to Setting Up the Shopify Ajax API

Setting up the Shopify Ajax API involves integrating AJAX functionality into your Shopify store to provide an enhanced shopping experience. Here’s a step-by-step guide to help you get started:

Step 1: Set Up a Private App

Here’s how to create your private app in your Shopify store:

  1. Log in to your Shopify admin panel.
Log in to your Shopify admin panel
  1. Go to the “Apps” section in the left sidebar.
  2. Click “Manage private apps.”
  3. Create a new private app by clicking the “Create a new private app” button.
  4. Provide a name for your private app and configure the necessary permissions. Make sure to grant the app access to the data and features you plan to interact with using AJAX.
  5. After creating the private app, you’ll receive API credentials, including an API key and password. These credentials will be used to authenticate your app when making API requests.

Step 2: Obtain API Credentials

Once you’ve created your private app, take note of the API credentials:

  • API key: This serves as a distinct identifier for your app and will be used in your AJAX requests to Shopify.
  • Password: This is the secret key that, along with your API key, authenticates your app to access the Shopify API.

Keep these credentials secure, and don’t share them publicly.

Step 3: Set Up Your HTML

To incorporate AJAX functionality into your Shopify store, you’ll need to customize your HTML templates. The specific HTML files you modify will depend on the features you want to implement. Common templates include “product.liquid,” “cart.liquid,” and “collection.liquid.” Here’s what to do:

  1. Duplicate your current theme as a backup to preserve your original design and functionality.
  2. Access the Shopify theme code editor from your admin panel.
  3. Modify the HTML templates relevant to the features you’re adding. For instance, if you want to enable real-time cart updates, you’ll likely need to edit the “cart.liquid” template.
  4. Add HTML elements, classes, or IDs that will be manipulated by your JavaScript code to reflect the real-time data from the Shopify API.

Step 4: Create Your JavaScript File

JavaScript is the heart of your Shopify Ajax API implementation. You’ll need to write JavaScript code to make AJAX requests to the Shopify API and update your HTML dynamically. Here’s what to do:

  1. Create a JavaScript file, such as “custom.js” or “shopify-ajax.js,” where you’ll write your code.
  2. Inside your JavaScript file, use the API credentials (API key and password) you obtained in Step 2 for authentication in your AJAX requests.
  3. Write JavaScript functions to handle user interactions, make API requests, and update the HTML elements you modified in Step 3 with real-time data.
  4. Test your JavaScript code to ensure it’s functioning as expected. Pay special attention to handling errors gracefully and providing user-friendly feedback.

Step 5: Testing

Testing is a critical part of the process to ensure that your Shopify store’s AJAX functionality works smoothly. Here’s what to consider:

  1. Thoroughly test the implemented features. Make sure that AJAX requests to the Shopify API work as intended.
  2. Test the user experience to ensure that real-time updates are seamless and that error messages are clear and informative.
  3. Test your implementation across different browsers and devices to ensure compatibility.
  4. Debug and resolve any issues that arise during testing.
  5. Consider seeking feedback from potential users to identify any usability issues and areas for improvement.

Common Use Cases for the Shopify Ajax API

Developers often use AJAX techniques in combination with the Shopify Storefront API or Admin API to create dynamic and interactive features on Shopify-powered e-commerce websites. Here are common use cases for using AJAX in Shopify:

1. Implementing Real-Time Product Updates

Real-time product updates are a game-changer in e-commerce. With the Shopify Ajax API, your customers will continuously stay informed with the latest updates. Real-time updates can include:

  • Price changes: As prices are updated in your system, customers see these changes instantly. This transparency fosters trust and can result in increased purchases.
  • Inventory availability: When a product goes out of stock, the Shopify Ajax API can immediately update the product page to reflect this. Conversely, when an item becomes available again, customers will know right away.
  • Product variants: If you offer products with multiple variants (like size or color), real-time updates can show customers which variants are available or sold out, without the need for page refreshes.
  • New arrivals and restocks: Real-time product updates can prominently feature new arrivals and restocked items to grab customers’ attention as soon as they land on your website.

2. Creating Dynamic Shopping Carts

A dynamic shopping cart, powered by the Shopify Ajax API, provides numerous benefits for both customers and store owners:

  • Smooth interactions: Customers can add, update, or remove items from their cart without being redirected to a separate cart page. This keeps the shopping process seamless and engaging.
  • Instant totals: As customers make changes to their cart, such as quantity adjustments or adding promo codes, the cart’s total is updated in real time. This immediate feedback can encourage customers to complete their purchases.
  • Cross-sell and upsell: Use dynamic carts to suggest related products, upsells, or cross-sell items, increasing the average order value and driving more sales.

3. Enhancing Search Functionality

An improved search experience can significantly impact customer satisfaction and conversion rates. With the Shopify Ajax API, you can enhance search functionality by:

  • Live search and autocomplete: As users type in their search queries, AJAX can provide instant search suggestions and results, making it quicker and easier for customers to find what they’re looking for.

  • Filtering and sorting: Enable users to filter and sort search results without needing to reload the page. Dynamic filtering allows for a more personalized shopping experience, especially in large product catalogs.
  • Search result previews: When a user hovers over a search result, AJAX can provide previews of the product, including images, descriptions, and prices. This feature aids customers in their decision-making process.

4. Customizing the Checkout Process

A customized checkout process can streamline the path to purchase, reduce cart abandonment, and increase conversions:

  • Single-page checkout: With AJAX, you can create a single-page checkout where customers can enter shipping information, select payment options, and review their orders without navigating through multiple steps. This simplifies the process and reduces friction.
  • Real-time validation: AJAX can validate user inputs in real time, ensuring that customers receive immediate feedback about any errors or missing information. This prevents them from reaching the end of the process only to discover they missed a required field.
  • Address autocompletion: Implement address autocompletion during the checkout process, making it quicker and easier for customers to fill in their shipping information accurately.

5. Real-Time Inventory Management

Real-time inventory updates are crucial for customer satisfaction and efficient store management:

  • Inventory transparency: The Shopify Ajax API can display real-time stock availability on product pages. Customers will appreciate knowing whether a product is in stock before they invest time in the purchase process.
  • Out-of-stock notifications: When an item goes out of stock, the API can offer customers the choice to receive notifications when it’s restocked, providing valuable customer service.
  • Inventory insights: By monitoring inventory changes in real time, store owners can make informed decisions about restocking products, discontinuing certain items, and managing their supply chain more effectively.

How to Use the Shopify Ajax API

Using AJAX with Shopify involves making asynchronous requests to Shopify’s APIs. Here’s a step-by-step guide for using the Shopify Ajax API:

1. API Access and Authentication

To access the Shopify Ajax API, you need to authenticate your requests. Authentication is typically done through API keys and tokens.

First, you’ll need to create a private or custom app in your Shopify admin to obtain the API key and any other necessary credentials. Ensure that your app has the permissions for the actions you want to perform through the API.

2. Make AJAX Requests

To interact with the Shopify Ajax API, you’ll use JavaScript’s AJAX capabilities. You can use the older `XMLHttpRequest` or the modern `fetch` API.

In your JavaScript code, make sure to construct your AJAX request with the appropriate HTTP method (e.g., GET, POST) and include the necessary headers. The critical header to include is the `X-Shopify-Storefront-Access-Token`, which should contain your API key for authentication.

3. API Endpoints

Shopify provides a variety of API endpoints to access different aspects of your e-commerce store. Some common endpoints include products, collections, customers, orders, and more.

Consult the Shopify Storefront API documentation to understand the available endpoints and their functionality. You can use GraphQL queries to request specific data, making it flexible and efficient.

4. AJAX Request Example

To retrieve product information from Shopify using the Storefront API, you would construct a GraphQL query as part of your AJAX request. Here’s an example of fetching a product by its handle:

fetch(‘https://your-shop-name.myshopify.com/api/storefront/graphql.json’, {

  method: ‘POST’,

  headers: {

    ‘Content-Type’: ‘application/json’,

    ‘X-Shopify-Storefront-Access-Token’: ‘your-api-key’,


  body: JSON.stringify({

    query: `

      query {

        productByHandle(handle: “your-product-handle”) {








.then(response => response.json())

.then(data => {

  // Handle and display the product data on your website


.catch(error => {

  // Handle any errors or failed requests


5. Handling Responses

Upon receiving a response from Shopify, parse the JSON response to extract the relevant data. You can then use this data to update your web page or perform other necessary actions.

6. Rate Limiting and Best Practices

Shopify imposes rate limits on API requests to prevent abuse and ensure fair usage. Be aware of these limits to reduce the number of requests. Use best practices, such as minimizing unnecessary requests and handling pagination correctly when dealing with large datasets.

7. Testing and Error Handling

Thoroughly test your AJAX requests in different scenarios to ensure they work as expected. Implement robust error handling by checking the response status and content. Different status codes (e.g., 200 for success, 404 for not found, 429 for rate limiting) may require different handling logic.

\Check and handle 404 not found error

Utilize browser developer tools to inspect the network requests and responses for debugging and troubleshooting purposes.
