Question

I’m already having a free application in app store (itunes connect)
Now I want to add in-app purchase for that.
So, I created a new product in in-app purchase and trying to test it. Its saying the product id is invalid.
But I created new app in app store with product id’s and when I’m testing, its working fine.
Is it necessary to create new app to distribute my old app with in-app purchases. Can’t I add in-app purchase for already existing application?

Answer 1

Yes, you can add in-app purchases to existing apps that previously did not support them.
