Resources for Developers
The USPS Developer Portal provides the tools and documentation necessary for software developers to integrate USPS functionality into their systems. It offers a suite of APIs for address validation, price calculation, and label creation to streamline logistics.
Getting Started with APIs
The portal offers a clear path for developers to create an account, register their applications, and obtain OAuth tokens. Comprehensive onboarding guides help users move from initial setup to making their first API calls in a sandbox environment.
Address Verification
The Address APIs allow developers to verify and standardize addresses to USPS specifications. This service helps minimize shipping delays and errors by ensuring that addresses are accurate and complete before a label is even printed.
Domestic and International Pricing
Pricing APIs provide real-time, up-to-date pricing information for all USPS products and services. Developers can integrate these into their checkout processes to give customers accurate shipping quotes based on weight, dimensions, and destination.
Label Generation
The Label APIs enable the automated creation of shipping labels directly within a business's application or website. This includes support for various mail classes and the generation of necessary customs documentation for international shipments.
Tracking and Delivery Data
Developers can use Tracking APIs to provide their customers with real-time updates on the status of their shipments. This integration helps reduce customer service inquiries by keeping shoppers informed throughout the delivery process.
