I'm trying to set up two Fedex shipping methods in Expresso Store. I've set up a Fedex API account and have added the API Key, Password, Account number and Meter number that Fedex gave me. However, I always just receive the error "Meter number is missing or invalid.", even if I set the test mode to True.
Anyone know what I'm doing wrong? The meter number is definitely the one that Fedex gave me, with no hidden spaces or any other mistakes. I'm running Store 1.6.0 on EE 2.3.0
