How to Integrate an External Marketplace Link into My iOS App?

Hi!

I have an iOS app which I want to publish to the App Store. Within my app, users can scan physical item bar codes in grocery stores and earn points for their scans. They are then re-directed to a marketplace on the web, where they can spend these points on physical items (e.g. clothes).

Does App Store block such external linking to marketplace?

Thank you in advance!
