Examples of the disclosure enable a financial transaction to be automatically confirmed based on a similarity of factors between financial transactions. A previous case action may be used for a decision of confirming a financial transaction. A first request for authorization of a first financial transaction is received from a financial transaction processing computing device. One or more parameters associated with a cardholder account are identified, and it is determined, at a transaction score device, whether to approve the first request for authorization based on the one or more identified parameters. On condition that the first request for authorization is approved, the one or more parameters are updated based on one or more first factors associated with the first financial transaction such that a second request for authorization of a second financial transaction is analyzable based on the one or more updated parameters.
