This guide will teach you what makes UPS different from other carriers.
The goal of this guide is to walk you through UPS's competitive services, predefined parcels, service levels, and how to start generating production UPS labels with EasyPost.
EasyPost supports all of UPS's functionality, along with the full functionality of 120 other carriers. If you haven't shipped your first label with EasyPost, we recommend you check out our Getting Started Guide.
You can download UPS's documentation for their APIs at www.ups.com/upsdeveloperkit. Their documentation will include additional information about various fields and formats they accept. Please note, the interface may not be identical to the API presented by EasyPost, as we standardize across multiple carriers.
