Nationwide customers will only see 90-days of transaction history with Credit Card accounts in Money Dashboard. This is due to the programming of Nationwide's Open Banking system, which Nationwide have limited to 90-days due to a technical oversight.
Nationwide have provided the following,
For Credit Cards: We are currently experiencing an issue in which if a date range for credit card transaction data is requested, then the member's most recent actions will not be returned - this is planned to fixed in Q2 2020. It is possible for TPPs to retrieve these transactions by either: requesting credit card transactions by not supplying a date range which we will return the current transactions made since the last statement, or by sending a second request of up to 90 days of transactions by supplying a date range which will return transactions up to the last statement. Both of these responses will provide up to 90 days of credit card transactions.
We are continuing to push to have this extented, as we feel that 90-days of transaction history isn't good enough for our customers.
