It changes the way you build it. If it only exists in one place at all times (sidebar?) then from a development stance you treat it differently.
Pretty sure this is unnecessary if you have an API key for an admin account under Site Settings.
I would suggest formalizing it under Marketplace.
Just be aware that what you’re asking for isn’t trivial or quick. It’s a pretty advanced build so it’ll take someone a significant amount of time to get it right.
