Event name:listing.submissionSent when Synup finishes attempting to sync a business listing to a directory (Google, Facebook, etc.), triggered by profile updates or new directory submissions. Delivered to your Webhooks URL (Listings webhook). One delivery per status change — a move from incomplete to success sends two separate calls. Note the compact envelope: there is no top-level timestamp or account_id, and the location is identified by the Base64 id inside data.
