Priority1 API



The Priority1 API was designed to be easy to use and simple to test in order to help our customers and partners get up and running quickly. Use the LTL endpoints to obtain rates, dispatch & track shipments, and access the documents needed for managing your business.

The current version of the API is v2, which is not backward compatible. Any organization who went live before February 2018 utilizing any XML-based functionality will require a version bump to use the new APIs.

To obtain access or for more information, please contact your Priority1 sales representative.
