Card balance updated webhook enhancements

We have added the ability to select the “real” or “optimistic” balance of a card when sending a “Card balances updated” webhook from Secure Payments. Now, you have greater control over the card balance information you receive from Secure Payments, reducing over-authorizations during rapid transaction attempts. This option applies only to cards issued through a Bring-Your-Own-Issuer-Processor (BYOIP) configuration and the option can be determined for each Issuer configuration.
