name: CMG XC EventHub
summary: >-
  Capital Markets Gateway advertises a real-time event notification surface for the CMG XC workflow
  platform, called EventHub. It is documented only as prose in the public product FAQ — no AsyncAPI
  document, event catalog, channel list, payload schema, subscription reference or endpoint is
  published anywhere on a public host.
delivery: >-
  Described by CMG as "real-time event notifications ... delivered via EventHub", consumed by internal
  trade processing and OMS platforms for straight-through processing. The transport (webhook callback,
  message broker, or streaming subscription) is not stated publicly.
events:
- name: trade release

    "event-driven alerts for launches, amendments and pricings are also supported."

gap:
  what_is_missing:
  - No AsyncAPI document at any public URL.
  - No published channel, topic or event-name catalog beyond the three examples quoted above.
  - No payload schemas for any event.
  - No public subscription, delivery, retry or signature/verification documentation.
  who_can_fix_it: provider
  remedy: >-
    Publish an AsyncAPI document for EventHub at a stable public URL, with a channel per platform
    event and a message schema per payload. The three event kinds CMG already names in its own FAQ are
    enough to start; an integrator currently cannot see the event names, the payload shape, or how
    delivery is authenticated without becoming a customer first.
