Thread: API Authorization failure.

  1. #1
    USPS server returned error: API Authorization failure. User is not authorized to use API DeliveryConfirmationV3. [80040B1A]... Please how can I solved this error?, so I can be able to print label with my ShipRush Desktop.

    Can you clarify how you're using ShipRush? The error above indicates you're trying to create a shipment via the USPS servers directly, which is no longer supported.

    Thank you,

    I am using ShipRush as I've been using in the past. I'm running the ShipRush USPS for StandAlone from my desktop and it keeps showing the error after I have filled the receiver's address details. It didn't create a label after I've clicked on Ship.

    The error indicates you're trying to use the plain USPS option we had available before, but is no longer supported.

    Are you trying to use ShipRush Discount Postage? Possible you have the plain USPS icon still available and are launching the wrong version?
