App Functions — Write the Handler

Start from the trigger's default template and its types — fetch both with salla_functions action=get, app_id, trigger. Copy the template verbatim and write all your code inside the body. Keep the wrapper's first and last lines exactly as given (full rule plus local type-check → salla-app-functions-validate).

This skill assumes sync-vs-async is already decided in salla-app-functions-design (a sync merchant_actions trigger blocks/modifies the operation; an async event is fire-and-forget).

Keep the handler minimal — delegate to your own API
