spec_type: Webhooks
notes: >-
  Goldman Sachs Transaction Banking (TxB) documents a webhook / notification
  surface for real-time, push-based updates so clients stop polling the REST
  APIs. Captured as a webhook catalog from the published docs — Goldman Sachs
  does not publish a machine-readable AsyncAPI document, so no AsyncAPI spec is
  fabricated here. The Marquee/GS Quant analytics surfaces have no event feed.
service: Transaction Banking (TxB)
transport: HTTPS webhook (provider POSTs to a client-registered endpoint)
delivery: >-
  Notifications are pushed only when a subscribed object changes state, giving
  fresher data than polling. Payment-status transitions are the primary event
  class. A Positive Pay / incoming-payment review notification flow is also
  documented under manage-notifications.

    Webhook consumers sit behind the same mTLS + allowlisting trust model as the
    TxB request APIs; verify delivery authenticity per the TxB integration guide.
