GSO Shipping API made simple
GSO was acquired by GLS (General Logistics Systems) in 2016, making GSO a wholly owned subsidiary of GLS. Their service areas include Washington, Oregon, Idaho, Nevada, California, Utah, New Mexico, and Arizona. GSO offers ground and priority service levels. GLS is known for their expansive next-day delivery, priority overnight services at 40% less cost, per-pallet rates for LTL shipments, and later-than-average pickup and earlier-than-expected delivery times. They practice a green initiative and value community involvement.
Using EasyPost’s simple Shipping API, you can ship with GSO and dozens of others with a single point of integration.
