It's sad that you're downvoted, but how do you deal with sending of the product without a confirmation? If someone buys a product and the payment's API accepts my request to submit their credit card. I might want to know if it's accepted or declined before acting. Some businesses might afford to work and can undo changes. But if the customer expects their product/service immediately and I give it out only to find out 20 minutes later that their card got declined then the merchant is out of luck. In which case they will go after Stripe to cover their losses. Perhaps they should have 2 API's. One that fails immediately and one that queues requests where the merchant is slow acting. Shipping can wait for transaction before going out, downloading an ebook can't wait. The merchant will then have to decide which way to go based on their business.
