No. This won't happen, PCI-DSS is getting harder and harder to comply, and the whole industry trend is to not move credit-card data through your own site.

That way we could use it to auto-send an email explaining that the subscription with corresponding CC will end at which time a new subscription will need to be paid for. Or, we, as a company, may wish that they call us so we can manually replace expiring CC with a new card in the ARB so that the current subscription will continue without interruption.

Mailing operations depending on financial data, and operations on credit-card should, actually soon ...must, by made by the Payment Service Provider. Maybe Authorize.net has such a service.

We have tried really hard to be as helpful as possible on providing you a way to get the date you wanted. As said, it is probably stored in the logs in the history table, but it is something that we will not support, nor guarantee format compatibility. You can try to do an sql query and auto-action to grab it, but as said it is sensitive data, subject to PCI-DSS strictest standards, and you are on your own on this.

Other PSPs, like Paypal and 2Checkout do implement client-relation to update credit-cards and notify your customers. Authorize.net will have to implement the same sooner or later.

I'm now marking this thread as answered.
