WordPress REST API Development for Apps and Integrations
WordPress REST API development exposes your content as clean JSON so a separate frontend can use it. Omeiro builds custom endpoints, webhooks and WPGraphQL schemas, with authentication, for headless WordPress setups.

Planning WordPress REST API endpoints properly
Planning WordPress REST API endpoints begins with the consumer. List the screens in the frontend, the data each needs and how often it changes, then design endpoints that return exactly that instead of dumping raw posts. Smaller, focused responses are quicker, easier to cache and easier for frontend developers to use correctly.
Security and versioning matter early. Decide which routes are public, which need authentication and which user roles may write data, and never rely on obscurity. Documenting responses and keeping a version number prevents frontend breakage when the API changes. Share your frontend framework, hosting and any custom fields in use. Careful WordPress REST API development also handles errors and rate limits, so the frontend fails gracefully.
