I think it's the easiest way. Creating your own app or service from scratch, marketing it, and retaining users long-term is nearly impossible (seems like). All of those problems are solved by integrating with a 3rd party.. Granted, that has it's own risks and limitations, but seems worth it for small side projects.
Exactly. Just wondering are there any other third party platforms you are excited about? Recently I was checking - https://www.cloudflare.com/apps/
but can't find how revenue works on there.
Not sure they have launched that yet, but you can charge separately outside of Cloudflare
