ELEX Stamps.com Plugin – Authentication Failed Error

Customer:

I am using the stamps.com plugin with WooCommerce in WordPress. It is installed correctly, but when I go to calculate shipping I get the following error:
Stamps.com – Unable to Get Auth: Authentication failed.

I am pretty sure I have the correct UN and PW because I can use it actually to get into my stamps.com acct.

Please help.


Support:

If the authentication information like UserID or Password is not correct, you get this Auth: Authentication failed error.

We request you to check the UserID and Password once again. For more information on troubleshooting, please refer the Stamps.com troubleshooting article.

      Authentication error appears because of two reasons: 1) If the username and password entered for Stamps are invalid.2) Or if you are using the stamps credentials in the wrong API mode.
