The WordPress REST API allows external applications to interact with your site, but issues can arise. This guide provides steps to troubleshoot and resolve common REST API problems.

  1. Check Permalinks Structure:
    • Ensure that your permalinks structure is correctly set up. Go to “Settings” > “Permalinks” and save the settings to flush rewrite rules.
  2. Inspect Plugin Conflicts:
    • Deactivate all plugins to see if a plugin is causing the REST API issue. Reactivate them one by one to identify the conflicting plugin.
  3. Review Theme Functions:
    • Check your theme’s functions.php file for code that might interfere with REST API requests. Temporarily switch to a default theme to test if the issue persists.
  4. Check for .htaccess Rules:
    • Review your .htaccess file for any rules that might block API requests. You can temporarily rename the file to see if it resolves the issue.
  5. Consult REST API Documentation:
    • Refer to the official WordPress REST API documentation for guidance on resolving common issues and understanding API endpoints.

By following these steps, you can troubleshoot and fix REST API issues in WordPress, ensuring smooth integration with external applications.
