Hi Nationwide and Ob,
We've had a user connect a Nationwide credit card and the MerchantCategoryCode code returned has a length of 13 characters.
My understanding from the v3.1 specification is that the MerchantCategoryCode should have a minimum length of 3 characters and a max length of 4 characters and conform to the ISO 18245 standard.
The MerchantCategoryCode returned was "AMZN.CO.UK/PM"
The AccountId is: 1miFa0g3NNAyo1C25gBILrz0MUEi0kzsIyISOjBE
The TransactionId is: 880d51b5db3e13bc66d4036a7c835d76b19d94f3
Could we get some guidance on if this is the expected behaviour for this field please?
