Enable CORS on JSON API Wordpress

How to Enable CORS on JSON API Wordpress 🌐

Are you facing a frustrating CORS error on your WordPress site with the JSON API plugin? Don't worry, we've got you covered! In this blog post, we'll address the common issue of enabling CORS on a JSON API in WordPress and provide you with easy solutions to resolve it.

Understanding the Problem 🤔

The original poster mentioned that they had successfully enabled CORS on their WordPress site by adding header("Access-Control-Allow-Origin: *"); to the PHP header. However, when they tried using the URL provided by the JSON API plugin, the CORS setup stopped working, resulting in an error message: "No 'Access-Control-Allow-Origin'".

The Solution 💡

To enable CORS on the JSON API in WordPress, follow these simple steps:

Option 1: Modify .htaccess File

1. Access your WordPress installation via FTP or a file manager.

2. Locate the .htaccess file in the root directory.

3. Open the file in a text editor.

4. Add the following code at the beginning of the file:

<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept"
Header set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
</IfModule>

1. Save the changes and upload the modified .htaccess file back to your server.

2. Test the JSON API URL again.

Option 2: Use a Plugin

If modifying the .htaccess file seems daunting, you can use a plugin to handle the CORS setup for you. There are several plugins available in the WordPress repository, like "Enable CORS" or "WordPress CORS," that simplify this process.

Here's how to install a CORS plugin:

1. Login to your WordPress admin dashboard.

2. Go to Plugins > Add New.

3. In the search bar, type "Enable CORS" or "WordPress CORS" and hit enter.

4. Choose a suitable plugin from the search results.

5. Click on Install Now and then Activate.

6. Once activated, follow any additional instructions provided by the plugin.

7. Test the JSON API URL again.

Test Your Setup ✅

To confirm that CORS is now properly enabled on your JSON API, you can use the Test CORS website mentioned by the original poster, or any other suitable CORS testing tool.

Here's an example:

• Access the Test CORS website.

• Enter your JSON API URL (e.g., http://kiwa-app.loading.net/?json=info) in the testing tool.

• Click on the appropriate button to initiate the test.

• If CORS is correctly enabled, you should see a successful response without any error messages related to "Access-Control-Allow-Origin".
