Carrier tracking
4PX is a major cross-border logistics provider moving parcels from China to the US and Europe for marketplaces and dropshippers. Its tracking numbers are common across e-commerce platforms.
Trace detects 4PX tracking numbers automatically and returns normalized events, so your store can track 4PX, YunExpress, and Cainiao shipments through one API instead of three.
