  Fireflies publishes NO AsyncAPI document. Probed /asyncapi.yaml and /asyncapi.json on
  api.fireflies.ai, mcp.fireflies.ai and docs.fireflies.ai (all 404), listed the 19 public
  repositories in the firefliesai GitHub org, and read the full docs index at
  https://docs.fireflies.ai/llms.txt (zero matches for "asyncapi") — no event specification
  exists. Fireflies DOES have a real, documented event surface (two webhook generations plus a
  Socket.IO realtime stream), so it is captured below as a webhook/event catalog rather than
  fabricated into an AsyncAPI document.
description: >-
  Fireflies exposes three distinct event surfaces: legacy Webhooks V1 (single transcription-complete
  event), Webhooks V2 (three granular meeting-lifecycle events), and the Realtime API (Socket.IO
  over WebSocket, live transcription segments).
