I am working on in app purchases for content downloading.
Product list will return from the server and product id also. I am not clear about one thing:
Can I add new in app purchases without updating the app ? Because the product list will come from server side.
I just want to add In App Purchases from iTunesConnect and the product list on the server side.
Yes you can add new in app purchases without update the app.
You will need to add all of your product to iTunes connect & for sure get Apple approval.
When you return product like reten it with same IAP ID.
