Sennder: How Sennder cut dispatcher time and scaled tracking with one CO3 API
In X weeks, Sennder unified live vehicle data through a single CO3 API. Refresh improved from roughly 1 ping/10 min → ~1 ping/3 min, enabling auto‑statuses that remove ~8 minutes of dispatcher work per order across ~X loads/month now running on CO3.

INTRODUCTION
Sennder is Europe’s leading digital freight forwarder. Operating across >20 markets with roughly 120k full-truckload movements per month, the company connects enterprise shippers to a large, vetted carrier network. The operating philosophy is pragmatic—instrument first, automate second; keep one clean interface, design for carriers and the floor—so teams can focus on exceptions rather than screens.
“We sit between shippers and hundreds of carriers, so predictability is respect. With CO3, we brought more partners into one flow and cut the back‑and‑forth. It makes the day lighter for everyone involved.” — Name, Role, Sennder
WHY CO3→BEFORE→IMPLEMENTATION→AFTER
To keep the operation quiet and predictable at European scale, Sennder chose CO3 because it fit the way the teams already work: a single API for both owned fleet and subcontractors (no one‑off hookups), fast onboarding by asset class (minutes, not weeks), standardized event webhooks, and a carrier‑oriented, responsive support model that matched the cadence of the floor. With that foundation in place, the focus was on steadier signals and fewer interrupts—not on adding more tabs.
Delivery was measured and practical: Week X mapped dispatch flows and defined a geofence taxonomy; Weeks X–Yconnected the fleet plus top subcontractors and enabled order create/refresh with event webhooks; Weeks Y–Zautomated statuses, rolled out lane‑by‑lane, and QA’d accuracy. As refresh density reached ~one ping every three minutes, auto‑statuses became dependable and dispatch stopped babysitting the system—returning ~eight minutes per order, while most movements now flow end‑to‑end without a touch. Technically it’s straightforward plumbing: Sennder TMS ↔ CO3 API ↔ telematics providers/OEMs, with normalized data for automation and audit.
