Available Methods

Method	Result	Description
`initConnection()`	`Promise<boolean>`	Init IAP module. On Android this can be called to preload the connection to Play Services. On iOS, it will simply call `canMakePayments` method and return value which is required for the listeners to work properly.
`purchaseUpdatedListener((purchase: ProductPurchase) => {})`	`EmitterSubscription`	Register a callback that gets called when the store has any updates to purchases that have not yet been finished, consumed or acknowledged. Returns a React Native `EmitterSubscription` on which you can call `.remove()` to stop receiving updates. Register you listener as soon as possible and react to updates at all times.
`purchaseErrorListener((error: PurchaseError) => {})`	`EmitterSubscription`	Register a callback that gets called when there has been an error with a purchase. Returns a React Native `EmitterSubscription` on which you can call `.remove()` to stop receiving updates.
`getProducts(skus: string[])` skus: array of Product ID/sku	`Promise<Product[]>`	Get a list of products (consumable and non-consumable items, but not subscriptions). Note: With before `iOS 11.2`, this method will also return subscriptions if they are included in your list of SKUs. This is because we cannot differentiate between IAP products and subscriptions prior to `iOS 11.2`.
`getSubscriptions(skus: string[])` skus: array of Subscription ID/sku	`Promise<Subscription[]>`	Get a list of subscriptions. Note: With before `iOS 11.2`, this method will also return products if they are included in your list of SKUs. This is because we cannot differentiate between IAP products and subscriptions prior to `iOS 11.2`.
`getPurchaseHistory()`	`Promise<Purchase>`	Gets an inventory of purchases made by the user regardless of consumption status (where possible).
`getAvailablePurchases()`	`Promise<Purchase[]>`	Get all purchases made by the user (either non-consumable, or haven't been consumed yet). On Android, it can be called at app launch, but on iOS, only at restoring purchase is recommended (See: #747).
`requestPurchase(sku: string, andDangerouslyFinishTransactionAutomatically: boolean, obfuscatedAccountIdAndroid: string, obfuscatedProfileIdAndroid: string)`	`Promise<ProductPurchase>`	Request a purchase. `purchaseUpdatedListener` will receive the result. `andDangerouslyFinishTransactionAutomatically` defaults to `true` for backwards compatibility but this is deprecated and you should set it to false once you're manually finishing your transactions.
`requestPurchaseWithQuantityIOS(sku: string, quantity: number)` sku: product ID/sku quantity: Quantity	`void`	iOS only Buy a product with a specified quantity. `purchaseUpdatedListener` will receive the result
*deprecated ~~`buySubscription(sku: string)`~~ sku: subscription ID/sku	`void`	Create (buy) a subscription to a sku.
`requestSubscription(sku: string, andDangerouslyFinishTransactionAutomaticallyIOS: boolean, oldSkuAndroid: string, purchaseTokenAndroid: string, prorationModeAndroid: string, obfuscatedAccountIdAndroid: string, obfuscatedProfileIdAndroid: string)` sku: subscription ID/sku	`void`	Create (buy) a subscription to a sku.
`clearTransactionIOS()`	`void`	iOS only Clear up unfinished transanctions which sometimes cause problems. Read more in #257, #801.
`clearProductsIOS()`	`void`	iOS only Clear all products and subscriptions. Read more in below README.
`getReceiptIOS()`	`Promise<string>`	iOS only Get the current receipt.
`getPendingPurchasesIOS()`	`Promise<ProductPurchase[]>`	IOS only Gets all the transactions which are pending to be finished.

`presentCodeRedemptionSheetIOS()`	`Promise<null>`	iOS only Availability: `iOS 14.0+` Displays a sheet that enables users to redeem subscription offer codes that you generated in App Store Connect.
`endConnection()`	`Promise<void>`	End billing connection.

`flushFailedPurchasesCachedAsPendingAndroid()`	`Promise<void>`	Android only Consume all 'ghost' purchases (that is, pending payment that already failed but is still marked as pending in Play Store cache)
`consumePurchaseAndroid(token: string, payload?: string)` token: purchase token payload: developerPayload	`void`	Android only Finish a purchase. All purchases should be finished once you have delivered the purchased items. E.g. by recording the purchase in your database or on your server.
`acknowledgePurchaseAndroid(token: string, payload?: string)` token: purchase token payload: developerPayload	`Promise<PurchaseResult>`	Android only Acknowledge a product. Like above for non-consumables. Use `finishTransaction` instead for both platforms since version 4.1.0 or later.
`consumePurchaseAndroid(token: string, payload?: string)` token: purchase token payload: developerPayload	`Promise<PurchaseResult>`	Android only Consume a product. Like above for consumables. Use `finishTransaction` instead for both platforms since version 4.1.0 or later.

For upgrading/downgrading subscription on Android pass the second parameter with current subscription ID, on iOS this is handled automatically by store. You can also optionally pass in a proration mode integer for upgrading/downgrading subscriptions on Android
`validateReceiptAndroid(bundleId: string, productId: string, productToken: string, accessToken: string)` bundleId: the packageName productId: productId productToken: productToken accessToken: accessToken isSubscription: isSubscription	`Object\\|boolean`	Android only Validate receipt.
