Stream live timing

This is the endpoint behind the timing bridge. Send the lines your timing system emits, unchanged, and Outlap folds them into a persistent feed state for the event: running order, class and competitor details, the current flag and session name. Each lap that is new since the last packet is stored.

Use it for MyLaps Orbits, MyLaps Trackside/X2, AxWare and any RMonitor relay. If you’re building your own integration, you can send either form:

• lines: raw RMonitor records ($F, $A, $G, $J …).
• passings: one JSON object per completed lap, for systems that don’t speak RMonitor.

If both are present, lines wins.

Requires timing:write. Laps are matched to drivers by transponder, then car number, using the transponder list on the event’s Paddock tab.

Body

• vendor string default: rmonitor
  One of orbits, trackside, axware, rmonitor, generic. Recorded as the lap source (live:<vendor>).
• lines string[] optional
  Raw RMonitor records. Maximum 5,000. Lines not starting with $ are ignored.
• passings object[] optional
  Vendor passings. Maximum 2,000. See below.
• session_id string optional
  Attach laps to a session. Lap numbers are de-duplicated within it.
• bridge_version string optional
  Shown in Race Control. Truncated to 40 characters.
• source_label string optional
  Friendly name such as “Race Control PC”. Truncated to 120 characters.

At least one of lines or passings is required.

Passing object

• transponder string optional
  Or transponder_id.
• number string optional
  Car number. Either number or a transponder is required.
• name string optional
  Competitor name.
• lap_number integer optional
  Or lap. If omitted, laps are counted from the last one seen. A lap number already ingested is skipped.
• lap_time_ms integer optional
  Or lap_time as "1:42.311". Passings with no valid lap time are skipped.
• recorded_at string optional
  ISO 8601 timestamp.

Response

• ok boolean
  Always true on success.
• recognised integer
  Records the decoder understood. A persistently low number means the wrong output is enabled on the timing system.
• laps_decoded integer
  Laps found in this packet.
• laps_inserted integer
  Laps stored after removing duplicates.
• flag string | null
  Latest flag: green, yellow, red, chequered, white or purple.
• session string | null
  Latest session name from the $B record.

Behaviour worth knowing

• Idempotent. Resending a packet doesn’t duplicate laps. Existing laps are skipped by transponder and lap number within the session.
• Stateful. The feed state persists between packets, so you don’t need to resend $A registrations each time, though sending them after a restart is harmless.
• Heartbeat. A successful call marks the feed live. Use POST /feed/status to report stale, error or stopped.
• Packet limits. More than 5,000 lines or 2,000 passings returns 413.
