in app purchases

I have a service that can be accessed via browser extensions on Chrome and Firefox. I've had a request for Safari.

Setting up an account is done via a regular browser app, the browser extensions are free but an account with API keys to use it are by subscription.

My question is I assume Apple wants it share, is this correct?

The Safari browser extension requires and API key that is managed via our site. There is a subscription to use the service across different browsers and this is handled by our site NOT the extension. There would be a link to the admin site in the extension
