This is really impressive, like the rest of the Stripe API! Although many people here are asking about creating virtual banks and issuing cards to customers, it appears that the intended audience of this API is a business that has a Stripe account, that wants to be able to issue cards to employees/trusted officials that charge against that single Stripe account. There is no mention of issuing cards to external customers that link against their own, external accounts, right?

I ask because the webhook that Stripe fires at purchase time is fantastic, and you could build some great things if their API gave you access to authorized real-time purchase data for customers. This doesn't appear to facilitate that though.

Does anyone know of an API that would allow a Credit Card user the ability to grant real-time webhooks to a 3rd party as they swipe their card? The closest I've ever found would be setting up spending email spending alerts (that certain banks allow), and then forwarding the emails to said 3rd party. It's clunky, and would only work with a few banks. Something like this issuing API would work if Stripe allowed you to issue a card that was linked to a customer's existing card/account. They'd basically be saying, "If I swipe _this_ card that you sent me, I'm agreeing to let you get notified." The other way I've considered would involve creating your own bank and issuing your own cards, but that's real work on both the developer and the customer's part :)
