The `inAppPurchase` module emits the following events:
|
|
|
|
### Event: 'transactions-updated'
|
|

Emitted when one or more transactions have been updated.
|
|
|

## Methods
|
|
|
|
The `inAppPurchase` module has the following methods:
|
|
|
|
### `inAppPurchase.purchaseProduct(productID[, quantity])`
|
|
|
|
* `productID` String - The identifiers of the product to purchase. (The identifier of `com.example.app.product1` is `product1`).
|
|
* `quantity` Integer (optional) - The number of items the user wants to purchase.
|
|
|
|
Returns `Promise<Boolean>` - Returns `true` if the product is valid and added to the payment queue.
|
|
|
|
You should listen for the `transactions-updated` event as soon as possible and certainly before you call `purchaseProduct`.
|
|
|
|
### `inAppPurchase.getProducts(productIDs)`
|
|
|
|
* `productIDs` String[] - The identifiers of the products to get.
|
|
|
|
Returns `Promise<Product[]>` - Resolves with an array of [`Product`](structures/product.md) objects.
|
|
|
|
Retrieves the product descriptions.
|
|
|
|
### `inAppPurchase.canMakePayments()`
|
|
|
|
Returns `Boolean` - whether a user can make a payment.
|
|
|
|
### `inAppPurchase.restoreCompletedTransactions()`
|
|
|
|
Restores finished transactions. This method can be called either to install purchases on additional devices, or to restore purchases for an application that the user deleted and reinstalled.
|
|
|
|
[The payment queue](https://developer.apple.com/documentation/storekit/skpaymentqueue?language=objc) delivers a new transaction for each previously completed transaction that can be restored. Each transaction includes a copy of the original transaction.
|
|
|
|
### `inAppPurchase.getReceiptURL()`

Returns `String` - the path to the receipt.

### `inAppPurchase.finishAllTransactions()`
|
|
|
|

|
|
|
|
### `inAppPurchase.finishTransactionByDate(date)`
|
|
|
|
* `date` String - The ISO formatted date of the transaction to finish.
|
|
|
|
Completes the pending transactions corresponding to the date.
