I need help with this, please.
we want to do a marketing campaign where we do a collaboration with influencers and other businesses, we want to add a (discount code) for each partner so we can keep track of how many new subscribers we get from each partner because we will share revenue.
We will add a text box where the user enters the code, for example (code: Sara) and the user can get the discount.
The payment is all in (in-app purchase) inside the app.
So our question is: is that against apple guidelines?
And is there any tool that can help us to make the tracking Easy?
