Type Function Return value none Revision Current Public Release (2018.3326) Keywords Google, IAP, in-app purchases, restore store.purchase() store.*
Users who wipe the information on a device or buy a new device may wish to restore previously purchased items. This function initiates the process of retrieving all valid purchases.
Unlike Apple IAP, Google IAP does not include a
"restored" state for transactions. This function should still be called to retrieve all of the user's purchases, but all valid transactions will be of the
"purchased" state. When you do a restore, you should treat the returned restored purchases as normal purchases, but avoid making duplicate records in your file or database — essentially, before adding a purchase, check if it already exists in your file/database or overwrite it by its key.
