W3 Total Cache Abilities

Purge every W3 Total Cache cache type at once (page cache, minified assets, database cache, object cache) via the plugin's w3tc_flush_all() API. Use after a major site update, content migration, or when troubleshooting stale content.

{
  "type": "object",
  "properties": {}
}

Purge the W3 Total Cache page-cache entry for a single URL on this site. Resolves the URL to a WordPress post or page and purges that post's cached page and its associated archive pages via w3tc_flush_post(), leaving the rest of the cache intact.

{
  "type": "object",
  "properties": {
    "url": {
      "type": "string",
      "description": "Full URL on this site (e.g. https://yoursite.com/about/)"
    }
  },
  "required": [
    "url"
  ]
}

Purge only W3 Total Cache's minified/combined CSS and JS assets via w3tc_minify_flush(), leaving cached pages and other cache types intact. Use after changing theme or plugin styles/scripts when cached HTML is still fine but combined assets are stale.

{
  "type": "object",
  "properties": {}
}

Flush only the object cache (Redis/Memcached/APCu when W3 Total Cache manages it) via w3tc_objectcache_flush(), leaving the page cache and minified assets intact.

{
  "type": "object",
  "properties": {}
}
