Directory listing synced (success/incomplete)
Event name: listing.submission
Sent 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.
Headers
sha256=base64(HMAC-SHA256(signing_secret, raw_request_body)). Present when the account has generated a signing secret; verify before processing.
Payload
Response
Acknowledge with any 2xx. A non-2xx (or timeout) is recorded as a failed delivery; failures are logged but not automatically retried at this time.
Changes
Webhooks have no change history: a webhook is keyed by its event name rather than a path and method, so no recorded change can name it.
