USPS will do planned maintenance on its APIs on Thursday, November 5, from 8:00 PM to 12:00 AM ET (5:00 PM to 9:00 PM PT).

During this window, some USPS API services may have a brief disruption. USPS will update systems one at a time, not all at once. Each disruption should last only a few minutes.

USPS says these APIs may be affected:

Containers
Domestic Labels
International Labels
Open and Distribute
Payments
SCAN Forms

USPS says package delivery is not affected.

We will post an update when the window ends or if USPS reports a problem.
