InAppPurchase vs. Outside payment (Stripe)

This is more like an iOS specific question. I’m hoping someone with the previous experience of deploying an app with subscription (and was rejected. :wink: ) would share.

So I’ve deployed an Ionic based app on iOS (and soon Android). This is a member-only app which I will want them to pay for later. If I let them pay outside of the app (ie, new window, or maybe InAppBrowser, will use Stripe, but that’s irrelevant), will my app be rejected by Apple?
