Overview

Interface for transaction APIs including Kongregate micro-transactions, user item management, and App Store reciept validation.

This API can be used to query the server to determine if a Kongregate user owns a particular item. Currently, the functionality provided by this API is used for cross-promotion between games. For example, a bonus item in one game can be awarded by obtaining a badge in another.

`– requestUserItemList`

Call this function to request the user’s inventory from the remote server. Once the list of items has been retrieved, a KONGREGATE_EVENT_USER_INVENTORY event will be broadcast, at which point you can call hasItem: to determine if the user owns a specific item.

- (void)requestUserItemList

Declared In

KongMtx.h

`– hasItem:`

Used to check if a user owns an item with the given identifier. Only valid after a call to requestUserItemList generates the KONGREGATE_EVENT_USER_INVENTORY event. It is recommended you persist the value of this call to disk once it returns true so that repeated requests to the server don’t need to be made.

`identifier`	The Kongregate item identifier

True if the user has the specified identifier in their inventor
