OnTrac (LaserShip) Tracking API & MCP

Query live OnTrac and LaserShip (ontrac) package status and scan history in a single synchronous GET request or MCP tool call. Following the OnTrac–LaserShip merger, both networks share one tracking system: lastscanned auto-detects legacy OnTrac C…/D… barcodes as well as LaserShip 1LS… and L[AEHINX]… numbers, returning a normalized TrackingResult JSON payload—with zero enterprise shipper contract gating.

Overview & Quick FactsCopy Anchor Link

Why developers use lastscanned for OnTrac / LaserShipCopy Anchor Link

• No enterprise shipper account or EDI/webhook contract: Official OnTrac / LaserShip API credentials are restricted to contracted high-volume shippers. lastscanned lets any merchant, 3PL dashboard, or WISMO AI agent query OnTrac and LaserShip numbers synchronously via GET /v1/track/:number.
• Clean event code normalization: OnTrac's raw payload mixes dozens of 2- to 4-letter internal event codes (OFDL, FOTO, NFRP, CUPT, CUDM, DLAY) and labels routine transit delays as "Pending". lastscanned maps every OnTrac event code into the 7 standard statuses while preserving the full event description in message.

Tracking Number Formats & Auto-Detection (matches vs mayMatch)Copy Anchor Link

OnTrac is evaluated sixth (#6) in lastscanned's two-pass detector:

When is ?carrier=ontrac optional vs required?Copy Anchor Link

• Optional (auto-detected): All C/D + 14-digit OnTrac numbers, 1LS… LaserShip numbers, and L[AEHINX] + 8-digit legacy LaserShip numbers auto-detect in Pass 1 with zero collisions against UPS, USPS, DHL, or FedEx.
• Required (?carrier=ontrac): Custom merchant reference numbers or numeric-only shipper order IDs inducted into OnTrac without a standard C/D or 1LS prefix.

Raw status & scan codes: statusDescription carries OnTrac's EventShortDescription, top-level message carries EventLongDescription, and events[].code preserves the raw OnTrac event code (OE, CUPT, OFDL, OD, FOTO, DLVD, DN, RETN, etc.).

Carrier-Specific Status & Integration NotesCopy Anchor Link

• Exact UTC (timestamp) and scan-local (localTime) clocks: OnTrac provides both UtcEventDateTime and ZonedEventDateTime on every scan, so both timestamp and localTime are populated with second-level precision.
• Estimated delivery behavior: While a package is still in label_created (before OnTrac receives the physical parcel), estimatedDelivery is null (matching the OnTrac tracker's "Pending" state). Once inducted, estimatedDelivery reflects ExpectedDeliveryDate.
