Action and Filter Hooks
There are numerous action and filter hooks throughout the plugin to allow for advanced users to customize virtually any aspect of the article before it's sent to Apple News. Many larger publishers have used these hooks to create detailed custom templates or modify the post content specifically for Apple News. If you're unfamiliar with hooks in WordPress, the core documentation on actions and filters is a great place to start.
We're providing documentation here on these hooks so everyone is aware of what's available, but as always it's best to view them in the source code and see them in action if you need more clarity on how they can be used. We've listed all hooks below alphabetically, but if you click through for more details on a hook, there is a link to the source file to make it easy for you to find them if needed.
Action hooks are used to trigger custom functions that rely on knowing when a specific piece of code executes or to insert additional content on template pages. They sometimes are accompanied by parameters that are relevant to the specific action.

Filter hooks are used to modify a variable. The first parameter is always the data to be modified and additional parameters may also be provided that are relevant to that specific filter. If you're hooking a filter your function must return the data, even if unmodified, or it will simply delete the value.

apply_filters( 'apple_news_post_status_cache_expiration', $cache_expiration, $state )
Allows you to modify the cache time for API responses. Most responses are cached to avoid repeatedly hitting the API, which would slow down your admin dashboard. $cache_expiration is the current cache time and $state corresponds to the current Apple News API status for that post. Different statuses are cached for different times since some are more likely to change quickly than others.

apply_filters( 'apple_news_is_post_in_sync', $in_sync, $this->id, $api_time, $local_time )
Modifies whether or not the post is in sync with Apple News. By default, the plugin simply compares the last modified time to the last time it was pushed to Apple News. If you want to apply custom logic, you can do that by modifying $in_sync. The most common use case is to not update posts based on custom criteria. $this->id contains the post ID. $api_time contains the timestamp when the article was last pushed to Apple News. $local_time contains a timestamp with the last time the post was updated in WordPress.
apply_filters( 'apple_news_skip_push', false, $this->id )
