Explanation

This indicates that the configuration setting you specified is not valid. Avalara supports configuration values at the account level and the company level. To set configuration values at the account level, call SetAccountConfiguration. To set configuration values at the company level, call SetCompanyConfiguration.

Configuration values are either Avalara-defined name/value pairs or customer-defined name/value pairs. All customer-defined name/value pairs have the prefix X-. To define your own configuration setting values, please prefix the name with `X-.

For a list of Avalara-defined name/value pairs, please call GetAccountConfiguration or GetCompanyConfiguration.
