When I execute the getMerchantDetailsRequest request in c# with the latest nuget package (AuthorizeNet version 2.0.1) it always fails with this error.
"There is an error in XML document (1, 40)."
I copied the code from your API documentation: https://developer.authorize.net/api/reference/#transaction-reporting-get-merchant-details
It has worked all the time until today.
This issue happens on every sandbox account regardless of ApiLoginID/ApiTransactionKey or OAuth2.0 authentication.
However, the Rest API works.
