Messages

When rating a Shipment or Pickup, some carriers may fail to generate rates. These failures are returned as part of the Shipment or Pickup as part of their messages attribute, and follow a common object structure.

It is important to note that the message value for any member of this list comes directly from the carrier, not from EasyPost. This means that if you see an authentication or other non-shipping error here, it is not an issue between you and EasyPost, it is an issue between you and the carrier, or an issue with the given data.
