benecaster_outlinks_health_exclusions_save_before

Fires immediately before Link Health’s exclusions are saved, from the Exclusions form on Settings → Link Health or the PATCH /benecaster-outlinks/v1/link-health/exclusions route.

Both arguments are [ 'domains' => …, 'post_types' => …, 'categories' => … ]. $exclusions holds the cleaned lists about to be saved: domains in lower case without a leading www. (a pasted URL is reduced to its host), post types from episode, page and post, and categories as term ids. A list the request did not send is the same in both arguments.

It fires only for a request that sends at least one of the three lists and passes validation. A refused request (400, where nothing is saved) fires nothing, and so does a request with none of them.

Link Health is install-wide and needs Outlinks switched on for at least one show, so the hook never fires while Outlinks is off for every show or the licence has lapsed.
