Round history

Finished rounds of shared-round games (today only Flip Jet), with crash points and times. Use it to reconcile with the /round/finish callback: to find rounds whose callback you did not receive, or to look up one round by number.

Added in 2.34.0

Both endpoints are authorised like launch-game: the Api-Key header with your API key, from an allowed IP. Answers use the usual {"success": true, "data": ...} envelope; errors are described in Errors.

History starts on 2026-10-14, when 19flip began recording rounds. Earlier rounds are not available.

The list also contains Golden Flight purchases (type golden_flight) of all casinos, interleaved with shared rounds in game_round_id order; a purchase of another casino's player comes with empty bets. Filter on type if you only need shared rounds.

GET /api/operator/v1/rounds

Lists finished rounds in increasing game_round_id order.

GET /api/operator/v1/rounds?game_id=flip-jet&from=2026-10-14T05:00:00Z&to=2026-10-14T06:00:00Z&limit=500 HTTP/1.1
Host: games.19flip.com
Api-Key: <your api key>

Parameter	Required	Description
game_id	yes	e.g. flip-jet.
from	no	Rounds with finished_at ≥ this time (ISO 8601; give a timezone or Z).
to	no	Rounds with finished_at < this time.
after_round_id	no	Rounds with game_round_id greater than this. Use it to page.
limit	no	1–1000, default 100.
only_with_bets	no	true: only rounds in which your players had bets. Default false.

Response:

{
  "success": true,
  "data": {
    "items": [ { "game_id": "flip-jet", "game_round_id": 327859, "...": "..." } ],
    "has_more": true
  }
}

has_more is true when more rounds match. To get the next page, repeat the request with after_round_id set to the last game_round_id you received.

A round appears here about a second after it ends. Rounds come every 10–20 seconds, so an hour is roughly 200–350 rounds.

GET /api/operator/v1/rounds/{game_round_id}

One round by number.

GET /api/operator/v1/rounds/327859?game_id=flip-jet HTTP/1.1
Host: games.19flip.com
Api-Key: <your api key>

game_id is required. Response: {"success": true, "data": <round object>}. A round that does not exist, has not finished yet or was played before history began answers 404 with code NOT_FOUND.

Reconciliation recipe

1. Every few minutes call GET /rounds?game_id=flip-jet&only_with_bets=true&after_round_id=<last round you processed>.
2. For each item you have no /round/finish for, process it exactly as if the callback had arrived. Deduplicate on game_round_id, as for the callback's idempotency_key.
3. Remember the last game_round_id and continue from it.
