Route Optimization API

The most powerful route optimization engine on the market.

Optimize tens of thousands of stops in a single optimization, and parameterize around the constraints that make sense for your business. Need a GUI to display and alter routes? Send has you covered there, too.

Built for easy integration

If you’re moving off an existing provider, Send can mirror your input data formats to make your transition as seamless as possible.

A solution that scales as you do

Carriers of all sizes use Send for optimization - 1,000 stops to 100,000+ stops in a single optimization, no pre-batching required.

Visualize your operations

Effortless tweaking and last-minute accommodation with a powerful interface that allows you to drag and drop to re-optimize and split or merge routes at the click of a button.

Designed by operators, for operators

Send’s route optimization API is built to support constraints that matter to your operation. Our map-based interface provides dispatchers and operations managers the power to manage route composition as they see fit.

Need to make a change on the fly? Powerful drag and drop functionality allows you to reassign stops and auto-reoptimize automatically. Route metrics like duration, distance, number of stops, and ETAs are built-in.
