WordPress teams build custom REST

Original: Going Headless From the Inside Out: Native WordPress API Customization

Short summary

WordPress teams can build lightweight custom REST API endpoints using register_rest_route to serve optimized data to React frontends without third-party plugins. Filtering payloads at the server level reduces network bloat and improves performance while retaining WordPress's familiar authoring interface. This hybrid approach enables modern decoupled architecture without infrastructure migration.

  • Use register_rest_route to create custom endpoints that return only the fieldsets your frontend needs
  • Filter payloads at the server level to reduce database and network overhead
  • Maintain WordPress's content editing experience while unlocking decoupled React frontend freedom
