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. Click on the name of an action hook for more information about that specific hook.
