Hook And Filter Reference

This reference documents Alpaca’s public PHP hooks, JavaScript extension points, and browser-side extension APIs.

Scope

• Includes the main alpaca plugin only.
• Includes dynamic REST action names created with do_action( 'alpaca_rest_' . $action_type, ... ) and do_action( 'alpaca_rest_error_' . $action_type, ... ).
• Includes JavaScript wp.hooks extension points and the public window.alpaca.itemDatapoints browser API exposed by the React application.

How To Use This Reference

Each PHP or JavaScript hook entry includes:

• The hook type (action or filter).
• A purpose statement focused on runtime behavior.
• The parameter list in call order.
• A source reference with the current file path and line number or line range.

To refresh the PHP and JavaScript source file line references after code moves, run npm run docs:refresh-hook-lines from the plugin root.
