IAP or 3rd party payment gateway for digital services app

Hi there,

I'm working on an app that would allow users to order some kind of digital service (e.g. copywriting or logo design), in a way that users would buy "tokens" inside the app that could be traded for a design services. Would Apple allow to use 3rd party payment gateway (like Stripe) vs. In-App Purchases?

I know that for digital content purchases Apple requires IAPs, but in my case services are done somewhere else and app is used just to order and deliver digital goods.

Thanks
