Title: Problem with Get request Last modified: August 8, 2023 --- # Problem with Get request * [danielkam](https://wordpress.org/support/users/danielkam/) * (@danielkam) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-get-request/) * I am currently facing a difficulty with this endpoint i am developing. I always get a **“rest_no_route”** error while i have well installed the plugin and everything is live. Can you please tell me what the problem is? By the way, a post request that i created within the same code is well working… * ```wp-block-code function custom_endpoint_get_user_info( $request ) {     $username = $request['username']; // Get the username from the request     $user_info = get_custom_user_id( $username );     if ( $user_info ) {         // User found, return the data in JSON format         header( 'Content-Type: application/json' );         $user_info_json = array(             'id' => $user_info         );         //echo json_encode( $user_info );     } else {         // User not found, return an error response in JSON format         header( 'HTTP/1.1 404 Not Found' );         header( 'Content-Type: application/json' );         echo json_encode( array( 'error' => 'User not found but working' ) );     }     // Return the retrieved information as a JSON response     return rest_ensure_response( $user_info_json ); } function custom_endpoint_get_user_infs() {     register_rest_route(         'custom/v1',         '/user-info/(?P[a-zA-Z0-9-_@.]+)', // Endpoint URL with a parameter for the username         array(             'methods' => 'GET',             'callback' => 'custom_endpoint_get_user_info',             'args' => array(                 'username' => array(                     'validate_callback' => 'rest_validate_request_arg', // Validate the username parameter                 ),             ),         )     ); } add_action( 'rest_api_init', 'custom_endpoint_get_user_infs' ); ``` Viewing 2 replies - 1 through 2 (of 2 total) * [Albert Bretado](https://wordpress.org/support/users/abretado1985/) * (@abretado1985) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-get-request/#post-16958170) * The code you’ve provided seems to define a custom REST API endpoint in WordPress. The endpoint is designed to retrieve user information based on the provided username. However, you’re encountering a “rest_no_route” error, which typically indicates that WordPress couldn’t find a matching route for the given endpoint. Let’s go through some troubleshooting steps to identify and fix the issue: 1. **Check the Endpoint URL:** Make sure you are using the correct URL to access the custom endpoint. It should be something like: `https://yourdomain.com/wp- json/custom/v1/user-info/username`. 2. **Flush Permalinks:** Sometimes, WordPress needs its permalinks to be flushed for new endpoints to work properly. Go to the WordPress admin dashboard, navigate to “Settings” > “Permalinks,” and simply save the current permalink structure without making any changes. This action flushes the rewrite rules and can help resolve routing issues. 3. **Namespace and Route:** Double-check the namespace and route you’ve registered for your custom endpoint. In your code, you’ve registered the route under the namespace `'custom/v1'` and route `'user-info/(?P[a-zA-Z0-9-_@.]+)'`. 4. **Confirm Plugin Activation:** Ensure that the plugin containing this code is activated and active. Sometimes, issues arise if the plugin isn’t activated or if there are conflicts with other plugins. 5. **Debugging Output:** You have comments around `echo json_encode($user_info);` and `return rest_ensure_response($user_info_json);`. Uncommenting these lines can help you debug the issue further by seeing the output directly. You can also use `error_log` to log messages to the debug log for more insight. 6. **Check for Typos:** Double-check for any typos or syntax errors in your code. Even a small mistake can prevent the routing from working correctly. 7. **Plugin and Theme Conflicts:** Sometimes, conflicts between plugins or themes can cause routing issues. Temporarily deactivate other plugins and switch to a default theme to see if the issue persists. 8. **WordPress Version:** Ensure that your WordPress version is up to date. Sometimes, new features or changes in updates can impact how custom endpoints work. 9. **Server Configuration:** Ensure that your server configuration supports pretty permalinks and mod_rewrite, as these are needed for custom endpoints to work correctly. 10. **Debugging Mode:** Enable WordPress debugging mode to get more detailed error messages. Add the following lines to your `wp-config.php` file: * Thread Starter [danielkam](https://wordpress.org/support/users/danielkam/) * (@danielkam) * [2 years, 10 months ago](https://wordpress.org/support/topic/problem-with-get-request/#post-16958622) * Thank you [@abretado1985](https://wordpress.org/support/users/abretado1985/) for your reply. I have tried steps 1 to step 9 and still nothingAs a reminder, it was working and suddenly no more working and it was also like that on another wordpress installation i had. Which line should i add in the wp-config.php to enable the debugging mode, please?
