On my iOS app, I need to add a button "Rate this app"..
I'm confused about the link to itunes: How can I know my APP_ID.
The application is not yet on the store but I'm ready for publication (I have everything that I need)
1) You must have prepared your app for submission on https://itunesconnect.apple.com. If not, please go ahead.
2) Then, it generates "Apple Id". That is an automatically generated ID assigned to your app.
This "Apple Id" is your APP_ID.
You can ses this(Apple Id) under "General App Information" section below the "App Icon".
