API Write Blocker

API Write Blocker is a security-focused plugin that prevents unauthorized or anonymous users from executing write operations through REST API, XML-RPC, and Admin-Ajax interfaces.

Unlike generic API blockers, this plugin enables fine-grained control over which HTTP methods (POST, PUT/PATCH, DELETE) are allowed, supports whitelist-based exceptions, and protects core endpoints without interfering with legitimate functionalities such as contact form submissions or plugin integrations.

🔐 Key Features

REST API Method-Level Blocking
* Independently block POST, PUT/PATCH, and DELETE requests.
* Whitelist specific REST routes (prefix match supported) to allow legitimate access (e.g., contact forms).
* Configure a custom HTTP status code and error message per request type.
