Description
The WordPress REST API is a great resource, but if you don’t want to use it probably you will want to close this door to your WordPress.
Unlike other popular plugins that aims to disable the REST API but only return an error, processed by the REST API, when a request is received, by default, this plugin removes all filters and actions related to WordPress REST API, and returns a 404 error for requests sent to the REST API URL endpoints, effectively blocking any use of the REST API.
Optionally you can set the REST API setting in Settings -> General page to “Logged In Only” for a less drastical action, to keep REST API access enabled but require the user to be logged in to accept the requests.
If you’re happy with the plugin please don’t forget to give it a good rating, it will motivate me to keep sharing and improving this plugin (and others).
SUPPORT: If you have any support question, please create an issue at the Github repository.
Requirements
- WordPress 4.7 or higher.
Features
- Disable WordPress core REST API for real by removing all filters and actions related to it and returning a 404 error for requests sent to REST API URL endpoints (e.g. https://example.com/wp-json/whatever ).
- Option to require user to be logged in to use the REST API instead of completely disable it.
Usage
To disable the REST API completely simply install the plugin from the Plugins page and enable it.
If you don’t want to disable the REST API but require user to be logged in instead, go to Settings -> General page and set the REST API to option to “Logged In Only”, and click Save Changes.
You can change the option back to “Off” if you want to disable the REST API again.
To return to WordPress default, simply deactivate the plugin.

FAQ
- How can I test if the plugin is working?
-
Use your browser to go to https://example.com/wp-json (replace example.com with your site domain). Your site will return a 404 error.
You can also check any regular page of your site to confirm the link to the REST API URL was removed from the HTTP header and from the HTML header.
If you have set the plugin to “Logged In Only”, no changes are made to the page headers, but you will receive the following response if you try the REST API without being logged in:
{"code":"rest_not_logged_in","message":"External REST API requests not allowed for this site.","data":{"status":401}}
