Is it possible to route in-app purchases to third party processors?

We are developing a marketplace that brings buyers and sellers together to exchange digital goods. I am looking to outsource the ecommerce portion and am looking at Stripe Connect to handle all the marketplace heavy lifting.

However, I do not know how to approach the in-app purchase part of it. I want to allow a buyer to subscribe to the content of a seller in the app but then have the funds forwarded to the Stripe Connect service such that it is delivered to the right seller, minus a platform fee that Stripe Connect handles for us. (I understand we will be paying two transaction fees in this scenario.)

Is there a way to accomplish this?

On the only scenario that you can use Stripe, would be if your app sells physical goods. Subscriptions, digital goods and everything else has to be done through Apples in app purchases.
