IAP Button is a way to purchase or restore products without writing code.
To add an IAP Button to your Scene, in the Unity Editor, select Window > Unity IAP > Create IAP Button.

Some app stores, including iTunes, require apps to have a Restore button. Codeless IAP provides an easy way to implement a restore button in your app.
To add a Restore button:
- Add an IAP Button to your Scene (Services > In-App Purchasing > Create IAP Button).
- With your IAP Button selected, locate its IAP Button (Script) component in the Inspector, then select Restore from the Button Type drop-down menu (most of the component's other fields will disappear from the Inspector view).

When a user selects this button at run time, the button calls the purchase restoration API for the current store. This functionality works on the iOS App Store, the Mac App Store and the Windows Store. You may want to hide the Restore button on other platforms.
If the restore succeeds, Unity IAP invokes the On Purchase Complete (Product) function on the IAP Button associated with that Product.
