Is using IAP obligatory in my case?

Hi there!
I'm trying to figure out whether using IAP is obligatory in my case?
or I can use a 3rd party payment provider like Stripe.
I scrutinized the Apple development guidelines, but the requirements are quite vague there.

Hi! I'm building a recruitment marketplace application.
There will be two user types: 1) Recruiter (posts a job); 2) Candidate (applies for a job). I plan to monetize it by asking a recruiter to pay a particular amount for each job post. No subscription, every job post will be charged separately.

Yes, you will need to use IAP for a posting.

Is iOS the only intended platform?


What is your refund policy?


Are you OK with Apple taking a piece of the transaction pie?


Note this may be better if moved to the IAP forum - see FAQ4 here:For Best Results - Read the Label
