get https://{siteUrl}/action.metadata_url_path_placeholder
Note: The path is a placeholder. The actual path is determined by the configuration of the app component.
When a user has navigated to the custom rule builder UI and selected a rule action (either through the sidebar or via a rule preset), Asana will make a request to the app to get the configuration form definition for the chosen rule action. This will initiate the flow to configure a new rule action or edit the configuration of an existing rule action. This is the endpoint and schema for updating rule actions; app triggers (V2) will be analogous.
