How to Append Text to the Description Field in Woocommerce REST API Responses

In the world of eCommerce, the ability to customize product data is essential. One common question that arises is how to modify the information returned by the Woocommerce REST API. Specifically, many developers want to add custom text to the description field of product responses. If you've tried using the add_filter function to alter the content without success, you're not alone. In this post, we’ll walk through a simple solution to achieve your goal effectively.

The Problem

When working with the Woocommerce REST API, you might find that using the add_filter method to modify the_content does not affect API responses. This can be frustrating when you want to present additional information or context within your product descriptions automatically. Therefore, we need a different approach to alter the API response directly.

The Solution: Using woocommerce_rest_prepare_product_object Hook

The solution lies in leveraging the woocommerce_rest_prepare_product_object hook. This allows us to intercept the API response just before it is sent back to the client, giving us the opportunity to customize it as needed.

Step-by-Step Implementation

Open Your Theme or Custom Plugin: Navigate to your active theme’s functions.php file or your custom plugin where you want to add this functionality.

Add the Following Code:
Here’s the code snippet you will use to append text to the product description in the API response.

Code Explanation

Hook: The add_filter function hooks our custom function into the Woocommerce API response workflow.

Function Parameters:

$response: The data structure holding product details.

$order: The current order object (not used here, but available).

$request: The request data object (also available for customization).

Empty Check: We check if the response data is empty to prevent any potential errors.

Appending Text: We define our custom text and append it to the existing description by using .=.

Return the Modified Response: Finally, we return the modified response back to Woocommerce.

Testing Your Implementation

After adding the code above, test the API response using any API client like Postman or through a browser using the appropriate REST API endpoint for products (e.g., /wp-json/wc/v3/products). You should see your custom text appended to the product description.

Conclusion

Customizing the Woocommerce REST API responses can significantly enhance the information provided to your users. By implementing the woocommerce_rest_prepare_product_object hook, you can easily append text to the description field. This method opens up possibilities for enriching your API responses with valuable content that enhances user experience.

Now you have the knowledge to extend your API options effectively. Happy coding!
