=== Frequently Asked Questions ===
How do I disable the WordPress REST API for non-logged-in users?
Use a small snippet that hooks into rest_authentication_errors to require authentication, or use a dedicated plugin. In this video, we use WPCodeBox to add the code and disable REST API access for guests.
Will disabling the WordPress REST API break my site?
Don’t disable it entirely. Many features and plugins (including the block editor) rely on the REST API. Instead, disable REST API access only for unauthenticated users so admin/editor functions still work.
Can I disable WordPress REST API but allow specific endpoints?
Yes, whitelist routes you still need (for example, from a plugin) while keeping other endpoints blocked for guests.
