About the charge method of ios application

Is the following method possible in the Apple application rule?

・ The app itself can be downloaded for free

・ You need a key to actually start using it

・ Teach the key to the person who paid your own money


Thank you.

No. From section 3.1.1 of the ASRG: “Apps may not use their own mechanisms to unlock content or functionality, such as license keys, augmented reality markers, QR codes, etc.”
