 * Hi,
 * I have a site that cannot have page cache, as some pages have automatic price
   updating, via an API.
 * The price updating is sensitive and so even a cache system at 5 minutes could
   make the prices high when compared to competitors.
 * Is there a way installing an immediately removing specific pages from cache?

 * Hi [@wood1e](https://wordpress.org/support/users/wood1e/),
 * You can fire up **edit_post** action on every post update with **do_action**.
   Hummingbird will clear the post cache, for the post ID that is passed to that
   action.
 * Best regards,
    Anton

 * hi,
 * Thanks for that, where do I find that in Hummingbird?
 * Will that actually make any difference?

 * Hi [@wood1e](https://wordpress.org/support/users/wood1e/),
 * Hummingbird will clear out the post cache once that post is updated automatically.
   No need to configure anything. You just need to make sure that your API is utilizing
   WordPress functions/filters and actions to update post data. If you are updating
   something without using pre-defined filters/actions, HB have no way of knowing
   that a post has changed.
 * Best regards,
    Anton
