• Project Title:
  • Application Programming Interface Strategy
  • Start Date:
  • Friday, March 3, 2017
  • Estimated Report Release Date:
  • August 2017

Application Programming Interfaces (APIs) allow applications to interact with each other and share data. APIs have been referred to as “the glue that connects information systems,” and allows for the flow of data.

For example, when a customer orders an item from an ecommerce website that utilizes the Postal Service Tracking API, the customer can click on a link that provides tracking information. The API connects the website to Postal Service systems that provide tracking and shipping information.

Various websites use Postal Service Web Tools APIs that help keep the customers and shipping partners connected and informed, thereby saving time and effort. Customer-Facing APIs ease integration with partner websites and provide a platform for future software development capabilities. The Postal Service offers many Web Tools APIs on usps.com such as Address Validation, Price Calculators, Shipping Labels, Package Pickup, and Tracking.

    The USPS is the worst mail delivery system I have ever had the unfortunate displeasure of dealing with. Lost a package going to S. Korea, registered and insured and they can't find the package after 3 months. They don't know where it's at or why it was rejected. Lost another package going to Michigan. I think the mail carriers just steal the packages, since there is no recourse for doing so. Oh but they'll delivery every piece of junk mail that is sent your way, or mail for people who haven't lived at my residence for years even after informing them that they don't live here. Reading the reviews seems that 10's of thousands of people lose their packages due to the shitbags at the USPS and there is nothing that can be done. It's a FELONY CRIME to mess with the mail yet their own organization can just lose packages at will with no recourse or charges brought against them. ALL the post masters should be brought up on fraud charges. And their "complaint" process is a joke, they don't care and have no intention on resolving any issue submitted to them. Absolutely the worst organization and piss poorly managed system on the planet.

    USPS APIs are used for tracking shipments placed through USPS. If a package was shipped using DHL, you would rely on DHL tracking. Our scope is limited to USPS Web Services so we cannot answer questions related to other shipping companies. Thank you for your question. Audit Team
