Action Hook for change post status

[Angeloverona]

We have post_publish hook to action of publish, but it more as needed, also hooks for pending for example to handle action after the button "submit to review" is pressed. Or post is saved as a draft.

I suggest you take a look at the wp_transition_post_status() function and associated transition_post_status hook in wp-includes/post.php.

This hook allows you to see the new status, the old status, and the post data.

2616  function wp_transition_post_status($new_status, $old_status, $post) {
2617      do_action('transition_post_status', $new_status, $old_status, $post);
2618      do_action("{$old_status}_to_$new_status", $post);
2619      do_action("{$new_status}_$post->post_type", $post->ID, $post);
2620  }
