A good way to automate some of this while still keeping manual control might be ChatOps. You could have a call back from Stripe that starts something like Hubot or Errbot which sends a message into your chat app (Discord, Slack, etc...) with the details. You can then reply to it with a command like "/provision subdomain" and it can then go off and do the work. You are still able to review everything but it simplifies the workflow.
