Similar to the enhancement thas was made for getCustomerProfileRequest (https://community.developer.authorize.net/t5/Ideas/UnMasked-Expiration-Date-in-Hosted-CIM-s/idi-p/49...), there should be an option to obtain the unmasked expiration date from getTransactionDetails.
This is important, for example in the case when a refund needs to be issued. The refund API expects the expiration date.
