This advanced course teaches developers to master the WordPress REST API for enterprise applications, covering authentication, security, performance, JavaScript integration, and large-scale decoupled architectures. Learn to build custom endpoints, secure API requests, optimize scalability, and integrate third-party systems.

Course Prerequisites

  • Basic understanding of WordPress development (themes, plugins, hooks).
  • Proficiency in PHP and JavaScript.
  • Familiarity with HTTP methods, JSON, and basic API concepts.

Course Outcomes

By the end of this advanced course, participants will be equipped to build secure, scalable, and performant enterprise-grade solutions using the WordPress REST API. They will gain hands-on experience in integrating with JavaScript frameworks, customizing endpoints, and optimizing large-scale API architectures.

Participants will be able to:

  • Develop and extend REST API endpoints within WordPress.
  • Implement secure authentication strategies including JWT and OAuth.
  • Harden REST APIs using best security practices and monitoring tools.
  • Optimize API performance with caching and query tuning techniques.
  • Build decoupled frontends using frameworks like React.
  • Debug, test, and scale WordPress APIs for high-traffic enterprise environments.
