What is WP REST API?

The WP REST API – OAuth 1.0a Server plugin implements the OAuth 1.0a protocol for delegated authorization on WordPress sites.

Developed by Joe Hoyle, this plugin has been available for 10 years and currently has 8K+ active installs. It holds a 3.7/5 rating from 7 reviews, with 57% 29% one-star ratings.

This plugin focuses specifically on the OAuth 1.0a standard for REST API authentication. It supports WordPress 4.4 and above, with the latest version 0.4.4 last updated on Aug 5, 2024. The plugin requires PHP 5.4 or higher and has been tested up to WordPress 6.6.5. For developers needing an oauth server wordpress solution, this plugin provides the server-side implementation directly within the WordPress REST API framework.

Key Features of WP REST API

• OAuth 1.0a Three-Legged Flow – Implements the full three-legged authorization process, allowing applications to request temporary credentials, user authorization, and final access tokens.
• REST API Index Integration – Authentication endpoints are discoverable through the REST API index under $.authentication.oauth1, making it easier for clients to find the correct URLs.
• Multiple Credential Endpoints – Provides separate endpoints for request tokens (/oauth1/request), authorization (/oauth1/authorize), and access tokens (/oauth1/access).
• HMAC-SHA1 Signature Support – Uses the HMAC-SHA1 signature method, which remains a reliable standard for OAuth 1.0a implementations.
• Flexible Parameter Placement – OAuth parameters can be sent via Authorization headers, query (GET) parameters, or request body (POST) parameters when encoded as application/x-www-form-urlencoded.
• Callback URL Validation – Enforces strict callback URL matching, requiring the scheme, authority, host, port, and path to match the registered application callback exactly.
• Application Management – Allows server administrators to register applications and control which external services can access the site.
• User-Centric Authorization – Lets individual users approve or deny which applications have permission to access their personal data on the site.

Installation & Setup

The lack of recent support activity means you may need to rely on community forums, the WordPress documentation, or your own OAuth expertise when troubleshooting issues. Consider testing the plugin in a staging environment first to ensure it meets your specific authentication requirements.
