Stripe integration

Hi there
I'm hoping to allow users of a site I'm building to set up a profile page and add a button to it where they can accept payments using Stripe. I don't want any cut of the money, just want it to be a feature they can have on e.g. a pro plan.

I was never sure how to do this and thought that I'd have to create some sort of marketplace integration. But then I saw how carrd.co does it on the pages that people host on there. Their instructions are here: https://carrd.co/docs/building/adding-a-stripe-checkout-button

Their solution involves providing your Stripe API keys to the platform so that it can call Stripe on your behalf. I wondered whether this was what people generally do to allow Stripe buttons in this way, or if there's another or more official way to do it.

Any advice on this would be gratefully received. I know there's Stripe docs but wondered whether anyone could give me a headstart here :)

Thanks!
