The U.S. Postal Service provides a suite of USPS Web Tools that customers may integrate into their own websites to validate or find mailing addresses, track and confirm mail delivery, calculate shipping rates, and create domestic or international shipping labels.
This service allows users to create a tracking label and an online customer record for a parcel shipped within the US, allowing the user or user's customers to track delivery status of that parcel.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
The python-ship SDK by benweatherman allows developers to access common shipping APIs from their Python applications. The UPS API's ground shipping methods and the USPS API's rate query and delivery confirmation methods are almost complete. The FedEx API's methods will be added in the future, but have not yet been implemented.
