API Tech Sheet
The USPS API Platform provides a dynamic, one-stop-shop of shipping capabilities to expand business reach
and increase efficiency. The USPS suite of APIs enables integrators to standardize an address, price a
package, create a label, find a USPS acceptance facility, schedule a carrier pick-up, and track a package from
entry to delivery. The USPS API platform also offers webhooks for near-real-time push notifications for tracking
events.
