That is a very, very smart niche to pick for an ebook. There is a clear customer need connected directly to money, a tightly contained topic, and a great opportunity for packaging e.g. working source code for what is, from the perspective of anyone doing non-toy payments, only a few dollars more.<p>Even though I already have working Stripe integration I sort of want to buy this to send additional signal to the market: "Informed producers! I want you to make more stuff like this. Being on the leading edge of technology and piecing together half-written docs and blog posts to get systems working sucks. Please make curated guides to how to solve real problems with the new hotness, ideally, ASAP after the new hotness is out. And ignore the guy who says he won't pay for it because his unwillingness to pay for your products or services is invariant under any course of action you take and can hence be dropped totally from your Karnaugh map."
