Bill of Lading API

The Bill of Lading API is written as a REST Web Service. It allows customers to send Southeastern Freight Lines information to supplement the paper Bill of Lading. It is sent to us by the shipper or the party that controls the freight. The primary benefits of the Bill of Lading API is that it allows the shippers to automatically integrate their systems and data, thereby, reducing manual data entry and resulting errors. The pro number needs to be sent to us and must also be printed on the paper Bill of Lading.
