Authorize.net’s API Requirements for CB Subs Active Subscription

Since there is no connection with CB Subs from Authorize.net to update the credit card on file, I am going to build a PHP script to send the updates through to Authorize.net. If the user’s card with Authorize.net is updated and the ARB Subscription is not disrupted for payments, does CB Subs disable the user subscription?

If a credit card stored at Authorize.net becomes expired, etc.. then on next renewal their subscription will expire. They'll just need to manually renew with their new credit card.

And what about the case where a site admin logs into authorize.net and manually updates the credit card that authorize.net has on file. Would this prevent the joomla user from having to update their cb subs account by keeping the authorize.net account status as active?

If you manually update the number in Authorize.net it should continue to work fine as normally on renewal.
