Fed-ex Plugin error

I am setting up the plugin for Fed-ex and get this error on the front end.

FEDEX Authentication Failed

I have checked all the settings and passwords and everything is correct, need some advice please. I have USPS working but Fed-ex doesnt.

Thanks,
Shawn

Hi,

Did you check that you don't have some extra spaces in your fields ?
It could be possible that an extra character is present at the end of a field so the authentication fails with fedex.

Regards,

I have checked everything and it looks like it is all correct, not sure what is going on with it.

I finally called Fedex and they checked their records, the API was off. Fixed and working now, just need to get CSS straight so it looks right.

Thanks for the help!
Shawn
