Stripe is by far the best developer experience I’ve had in my career working with third party APIs/services. The attention to detail is just second to none, and documentation is a big part of this.
Thanks! We still have a lot of work to do. (Making our integration experience simpler -- now that Stripe's functionality has grown so much -- is an area of current focus. If any HN readers happen to have specific suggestions on this front, feel free to email sebas@stripe.com.)
I know subscriptions have been significantly rehauled since then, but this was my only gripe. Stripe was absolutely excellent back when I used it.
