2. Open the event (map appears)

In plain words: “unlock this match/concert.” Send only the event number + your event code. The reply has zones/sections + counts. map.seats is [] here (avoids timeouts) — load seats in step 3 with section_id. Keep the session id.

Send: event_id (number) and access_code (event code). Nothing else.

{
  "event_id": "8",
  "access_code": "YOUR_EVENT_SECRET"
}

Event opened — zones/sections + counts; seats[] empty on purpose
