Infospica Headless API

Infospica Headless API is a WordPress REST API plugin that transforms your WordPress site into a secure, scalable headless CMS with fully isolated custom REST API endpoints.

Build modern frontend applications using Next.js, React, Vue, Angular, or mobile apps — powered by WordPress as a backend API, without touching the default WordPress REST API.

Looking for a secure WordPress REST API plugin for headless CMS? Infospica Headless API gives you a custom namespace, full CRUD support, ACF field access, and authentication control — all from a clean WordPress admin UI.

Why use Infospica Headless API?

Most developers using WordPress as a headless CMS face the same problems: the default REST API exposes too much data publicly, offers no namespace control, and has weak write protection.

Infospica Headless API solves all of that with a dedicated, configurable API layer purpose-built for modern headless WordPress architectures.

Key advantages:

• Fully isolated API namespace — no interference with default WordPress REST API
• Every endpoint requires authentication — no accidental public data exposure
• Write operations are locked to WordPress capability checks
• Works with any headless frontend: Next.js, Nuxt, React, Vue, Angular, or mobile

Key Features

• Custom WordPress REST API namespace with version control (/wp-json/my-api/v1/)
• Full CRUD endpoints — GET, POST, PUT, PATCH, DELETE
• Supports Pages, Posts, and Custom Post Types (CPT)
• ACF field support — include Advanced Custom Fields in API responses
• Authentication-aware — all endpoints require authentication; write operations require capabilities
• CSRF protection — nonce validation enforced for cookie-based authentication
• Pagination — ?page and ?per_page on all list endpoints (max 50 per page)
• WooCommerce-safe — core WooCommerce pages automatically excluded
• Clean admin UI — manage namespace, version, and enabled content types
• Clean uninstall — removes all plugin options on uninstall

Use Cases

• Headless WordPress with Next.js — fetch posts, pages, and CPTs via secure REST API
• WordPress REST API for React or Vue — isolated namespace, no public data leakage
• Mobile app backend — use WordPress as a content API for iOS or Android apps
• SaaS platforms — use WordPress as a headless CMS for multi-tenant applications
• ACF API — expose Advanced Custom Fields data via authenticated REST endpoints
• CPT API — serve Custom Post Type data to any external frontend or service

Security

• All endpoints require authentication — including read (GET) requests
• Write operations require WordPress capability checks (edit_posts, delete_posts)
• Nonce validation enforced for all cookie-based write requests (CSRF protection)
• Email addresses and sensitive user data never included in API responses
• WooCommerce core pages (Shop, Cart, Checkout, My Account) excluded automatically

Authentication

All endpoints require authentication.

Supported methods:

• Application Passwords (recommended) — available since WordPress 5.6; generate under Users → Profile and send as Basic Auth header
• WordPress login cookies — for browser or admin usage; write requests require X-WP-Nonce header or _wpnonce parameter
• Any authentication method that correctly sets the WordPress user context

Write operations are additionally restricted by WordPress user capabilities.
