RateV4 is not a valid API name for this protocol." The consumer keys and secret keys are incredibly long and I am not clear on what goes into the account # field. ANy help/clarification would be greatly appreciated. Side note: Why does USPS make this so difficult. Their instructions are poorly written and you have to jump back a forth through hoops to get any where.
