WP REST API

When to use

Use this skill when you need to:

• create or update REST routes/endpoints
• debug 401/403/404 errors or permission/nonce issues
• add custom fields/meta to REST responses
• expose custom post types or taxonomies via REST
• implement schema + argument validation
• adjust response links/embedding/pagination

Inputs required

• Repo root + target plugin/theme/mu-plugin (path to entrypoint).
• Desired namespace + version (e.g. my-plugin/v1) and routes.
• Authentication mode (cookie + nonce vs application passwords vs auth plugin).
• Target WordPress version constraints (if below 6.9, call out).
