iapConnector.setOnInAppEventsListener(object : InAppEventsListener {

            override fun onSubscriptionsFetched(skuDetailsList: List<DataWrappers.SkuInfo>) {
                /*provides list of product details of subs type*/
            }

            override fun onInAppProductsFetched(skuDetailsList: List<DataWrappers.SkuInfo>) {
                /*provides list of product details of inapp type*/
            }

            override fun onPurchaseAcknowledged(purchase: DataWrappers.PurchaseInfo) {
                /*callback after purchase being acknowledged*/
