Add your In-App Products and Subscriptions to the Google Play Developer Console

Establishing connection with Play console

iapConnector = IapConnector(this, "...")
            .setNonConsumableInAppIds("id1", "id2", "id3")   /*pass the list of Non-Consumable Product IDs*/
            .setConsumableInAppIds("id4", "id5")  /*pass the list of Consumable Product IDs*/
            .setSubscriptionIds("subId1", "subId2")   /*pass the list of Subscription IDs*/
            .autoAcknowledge()  /*to enable auto acknowledgement*/
            .connect()

Receiving events

iapConnector.setOnInAppEventsListener(object : InAppEventsListener {

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

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

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

            override fun onConsumed(purchase: PurchaseInfo) {
                /*callback after purchase being acknowledged*/
            }


            override fun onProductsPurchased(purchases: List<PurchaseInfo>) {
                  purchases.forEach {
        	  Log.d(tag, "A new product was purchaed : ${it.SkuId}")
			  when (it.skuId) {
		                "id1" -> {

		                }
		                "id2" -> {

		                }
		                "id3" -> {

		                }		          
		                "id4" -> {

		                }
		                "id5" -> {

		                }
		            }
		        }
            }

            override fun onError(inAppConnector: IapConnector, result: BillingResponse) {
                Log.d(tag, "Error : $result")

                when (result.errorType) {
                    CLIENT_NOT_READY -> TODO()
                    CLIENT_DISCONNECTED -> TODO()
                    ITEM_ALREADY_OWNED -> TODO()
                    CONSUME_ERROR -> TODO()
                    ACKNOWLEDGE_ERROR -> TODO()
                    FETCH_PURCHASED_PRODUCTS_ERROR -> TODO()
                    BILLING_ERROR -> TODO()
                }
            }
        })
