Sendle Tracking API & MCP

Query live Sendle (sendle) package status and scan history across Australia in a single synchronous GET request or MCP tool call. lastscanned auto-detects both 12-character QSS… tracking numbers and 8-character QS… order numbers in Pass 1 and returns a normalized TrackingResult JSON payload—without requiring a Sendle merchant ID or API key.

Overview & Quick FactsCopy Anchor Link

Why developers use lastscanned for Sendle instead of direct requestsCopy Anchor Link

• Works with Sendle's relaunched 2026 platform & SHA-256 proof-of-work gate: Following Sendle's 2026 platform relaunch, legacy api.sendle.com / track.sendle.com endpoints and old S-prefixed references were retired, and public lookups now require solving a cryptographic SHA-256 proof-of-work challenge (salt:nonce zero-bit difficulty check) before returning parcel data. Calling GET https://api.lastscanned.com/v1/track/:number handles the entire lookup and returns normalized JSON in one fetch().
• Tracks both QSS tracking numbers and QS order numbers: Whether your customer pastes the 12-character QSS000123456 parcel tracking number or the 8-character QS416938 order reference, lastscanned auto-detects and tracks both in Pass 1.

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

Sendle is evaluated thirtieth (#30) in lastscanned's two-pass detector:

Disambiguating Sendle (QSS + 9 digits) vs Purolator (3 letters + 9 digits)Copy Anchor Link

• Zero collision with Purolator: Even though QSS + 9 digits has the shape 3 letters + 9 digits, Sendle's matches() runs in Pass 1, whereas Purolator's /^[A-Z]{3}\d{9}$/i rule only runs in Pass 2 (mayMatch). Therefore, QSS000123456 always routes to sendle automatically.

Carrier-Specific Status & Integration NotesCopy Anchor Link

• Australian Eastern (Australia/Sydney) timezone normalization: Sendle timestamps are recorded in Australia/Sydney time without an explicit offset string. lastscanned preserves the local clock in localTime (deliveredAtLocal) and converts it to UTC in timestamp (deliveredAt).
• Status category mapping: Sendle's statusCategory values map deterministically to normalized statuses (received / label → label_created, transit → in_transit or out_for_delivery, delivered → delivered, returned → returned, cancelled → exception).
