Hey Arie,
We don't have examples showing how to integrate LimeLM order automation with Stripe, but we do have a number of customers who have done it successfully. Here's the best place to start: https://stripe.com/docs/tutorials/charges. Also, see our existing examples and article for code on how to generate product keys after an order has gone through: http://wyday.com/limelm/help/how-to-generate-product-keys-after-order/
