Has anyone gotten these third-party shipping software work like Shippingstation or Shippingeasy working with version 2.4.1. I get Credentials could not be validated or 400 unauthorized on the client end. Does 2FA need to be disabled for it to work?
Solved! Go to Solution.
You can disable 2FA and try again. For error 400 please check your logs if there is any error related to this.
Hope this can help you! Let me know if you need further assistance.

Except the Third party Shipping software, advise you have a try for the 3PL. They can offer you discount shipping rates, as well as one stop orders fulfillment service. Will be more convenient.
