WordPress REST API Endpoint Generator

Build a safer custom WordPress REST API endpoint without starting from a blank file. Configure the namespace, route, HTTP method, access policy and request argument, then generate PHP using register_rest_route().

What this generator includes

The generated starter code registers on rest_api_init, uses a namespaced route, includes the required permission_callback, and can add validation and sanitization for a request argument. Private endpoints use a capability check; public endpoints explicitly use __return_true.

Security matters more than the route itself

A custom endpoint is an application boundary. Treat authentication, authorization, validation and sanitization as separate concerns. A logged-in user is not automatically authorized to perform an action, and sanitizing input is not a replacement for checking whether a value is valid for your use case.

How to use the generated code

Use it as starter code in a custom plugin or controlled project code. Replace the example callback logic with your resource operation, choose the narrowest appropriate capability for private data, and test permitted and forbidden requests separately.

Important limitations

This generator cannot know your application’s data model, object-level permissions or business rules. Destructive or sensitive endpoints may require object-specific capability checks, stricter schemas, rate controls, and careful error responses. Review generated code before production use.

For outbound requests from WordPress rather than inbound endpoints, use the WordPress HTTP API Request Generator. For admin forms, see the Nonce & Form Security Generator.
