Скачать или смотреть How to Cache Custom WordPress REST API Responses Using Transients

In this video, I walk through how to add simple and effective caching to your custom WordPress REST API endpoints using transients.

I use this technique in a documentation system that loads content into a wrapper via AJAX. By storing the rendered response in a transient, we avoid re-running expensive logic on repeat requests — improving performance without the need for external caching plugins.

✅ Designed for use inside your own custom REST callbacks
✅ Transients are stored in the database, but speed up processing by skipping rendering
✅ Cache clearing is supported via hooks from popular plugins (WP Rocket, LSCache, W3TC, FlyingPress, and more)
✅ You can also clear the cache manually using a URL param or your own triggers
