Retrieving products
|
|||
|
|
===================
|
|||
|
|
|
|||
|
|
When your store's ``RetrieveProducts`` method is called it should fetch the latest product metadata and, optionally, ownership status for the current user.
|
|||
|
|
|
|||
|
|
When this process completes your store should call the ``OnProductsRetrieved`` method of the ``IStoreCallback`` supplied to your store upon initialisation, supplying a collection of ``ProductDescription`` that represent the items available for purchase.
|
|||
|
|
|
|||
|
|
Where products are owned by the user, your store may fill in the receipt and transaction ID fields of ``ProductDescription``; Unity IAP will invoke the application’s ``ProcessPurchase`` method for any transactions the application has not already processed.
|
|||
|
|
|
|||
|
|
Note that if the user is offline your store should retry until the user regains connectivity, taking care to avoid impacting game performance through aggressive polling.

Handling errors
|
|||
|
|
---------------
|
|||
|
|
|
|||
|
|
If products cannot be retrieved due to an unrecoverable error, such as the developer making an error with their store configuration, you should call the ``OnSetupFailed`` method of the ``IStoreCallback``, indicating the ``InitializationFailureReason`` responsible.
