This is a react-native native module library project for in-app purchase for both Android and iOS platforms.

The goal for this project is to have similar experience between the two platforms for in-app-purchase. Basically, android platform has more functions for in-app-purchase and is not our specific interests for this project.

We are willing to share same in-app-purchase experience for both Android and iOS.

Quick News

We had hard time supporting react-native-iap issues that did not provide working codes or any other examples. Therefore, we've decided to make an example app called DoobooIAP, which will contain all the features of IAP's and willing to continuously improve to support real-life examples. @Bang9 who had been helping many others for react-native-iap, is willing to support this repo so he will grant $300 of our income in opencollective as described in #855 🎉.
react-native-iap@4.0.8 ~ react-native-iap@4.1.0 is incompatible with react-native <0.61. This is fixed in react-native-iap@4.1.1 and above.
react-native-iap@4.0.0 has been released. You can see #716 for updates.
~~For early stages, You can install pre-releases version by running npm install --save reqct-native-iap@next~~
- next package isn't maintained currently. This will be re-opened when there is breaking change comming to support iap.
In the past, react-native-iap@^3.* has been updated very prompty for migration issues. Don't get suprised too much on why it is bumping up version so quickly these days.
1. Migrated to new AndroidX APIs.
2. Migrated to new Android billing client which is > 2.0.0.
  - acknowledgePurchase() has been added since 3.2.0 which is very important.
3. New Purchase Flow
4. More is comming in iOS 13.

Breaking Changes

Migrated to AndroidX in 3.1.0. Please check the Migration Guide.
Recommended to use 3.2.0 or above for react-native-iap@^3.0.0 users.
- Now, you should acknowledge purchase with non-consumable and subscription purchase from 3.0.0. See more about acknowledgePurchase.
- If you are using version ^3.0.* < ^3.1.0, please use acknowledgePurchase supported in 3.0.3. You can use method like androidpublisher.purchases.subscriptions.acknowledge.
3.4.0 introduces a similar flow to consumable purchases on iOS. You should update your code according to the recommended flow and pass false to andDangerouslyFinishTransactionAutomatically when callingrequestPurchase.

Configuration of Google Play & iTunes Connect

react-native-iap V3 note

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, developerIdAndroid, accountIdAndroid)` sku: product ID/sku developerIdAndroid: Specify an optional obfuscated string of developer profile name. userIdAndroid: Specify an optional obfuscated string that is uniquely associated with the user's account in.	`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, prorationModeAndroid: string, developerIdAndroid: string, userIdAndroid: 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.
`validateReceiptIos(body: Record<string, unknown>, devMode: boolean)` body: receiptBody devMode: isTest	`Object\|boolean`	iOS only Validate receipt.
`endConnection()`	`Promise<void>`	End billing connection.
`consumeAllItemsAndroid()`	`Promise<void>`	Android only Consume all items so they are able to buy again.
`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.
`finishTransactionIOS(transactionId: string)` transactionId: the transactionId that you would like to finish.	`Promise<void>`	iOS only Finish a transaction. Use `finishTransaction` instead for both platforms since version 4.1.0 or later.
`finishTransaction(purchase: InAppPurchase/ProductPurchase, isConsumable?: boolean, developerPayloadAndroid?: string)` purchase: purchase object isConsumable?: specify whether the product is a consumable developerPayloadAndroid: developerPayload	`Promise<void>`	This method works for both platforms and is recommended since version 4.1.0 or later. Equal to `finishTransactionIOS` + `consumePurchaseAndroid` and `acknowledgePurchaseAndroid`.
*deprecated ~~`buySubscription(sku: string, prevSku?: string, mode?: number)`~~ sku: subscription ID/sku prevSku: old subscription ID/sku (optional) mode: proration mode (optional)	`Promise<Purchase>`	Android only Create (buy) a subscription to a sku. 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.

There is no longer any need to call endConnection on Android as this is done automatically.

Usage

You can look in the RNIapExample/ folder to try the example. Below is basic implementation which is also provided in RNIapExample project.

Init IAP, In App Billing

First thing you should do is to define your items for iOS and Android separately like defined below.

import * as RNIap from 'react-native-iap';

const itemSkus = Platform.select({
  ios: [
    'com.example.coins100'
  ],
  android: [
    'com.example.coins100'
  ]
});

Get Valid Items

To get a list of valid items, call getProducts().

You can do it in componentDidMount(), or another area as appropriate for you app.

Since a user may first start your app with a bad internet connection, then later have an internet connection, making preparing/getting items more than once may be a good idea.

Like if the user has no IAPs available when the app first starts, you may want to check again when the user enters your IAP store.

  async componentDidMount() {
    try {
      const products: Product[] = await RNIap.getProducts(itemSkus);
      this.setState({ products });
    } catch(err) {
      console.warn(err); // standardized err.code and err.message available
    }
  }

Each product returns from getProducts() contains:

typeof `Product`

All the following properties are String

Property	iOS	And	Comment
`price`	✓	✓	Localized price string, with only number (eg. `1.99`).
`productId`	✓	✓	Returns a string needed to purchase the item later.
`currency`	✓	✓	Returns the currency code.
`localizedPrice`	✓	✓	Localized price string, with number and currency symbol (eg. `$1.99`).
`title`	✓	✓	Returns the title Android and localizedTitle on iOS.
`description`	✓	✓	Returns the localized description on Android and iOS.
`introductoryPrice`	✓	✓	Formatted introductory price of a subscription, including its currency sign, such as €3.99. The price doesn't include tax.
`introductoryPricePaymentModeIOS`	✓		The payment mode for this product discount.
`introductoryPriceNumberOfPeriods`	✓		An integer that indicates the number of periods the product discount is available.
`introductoryPriceNumberOfPeriodsIOS`	✓		An integer that indicates the number of periods the product discount is available.
`introductoryPriceSubscriptionPeriod`	✓		An object that defines the period for the product discount.
`introductoryPriceSubscriptionPeriodIOS`	✓		An object that defines the period for the product discount.
`subscriptionPeriodNumberIOS`	✓		The period number (in string) of subscription period.
`subscriptionPeriodUnitIOS`	✓		The period unit in `DAY`, `WEEK`, `MONTH` or `YEAR`.
`subscriptionPeriodAndroid`		✓	Subscription period, specified in ISO 8601 format. For example, P1W equates to one week, P1M equates to one month, P3M equates to three months, P6M equates to six months, and P1Y equates to one year.
`introductoryPriceCyclesAndroid`		✓	The number of subscription billing periods for which the user will be given the introductory price, such as 3.
`introductoryPricePeriodAndroid`		✓	The billing period of the introductory price, specified in ISO 8601 format.
`freeTrialPeriodAndroid`		✓	Trial period configured in Google Play Console, specified in ISO 8601 format. For example, P7D equates to seven days.

Purchase

The flow of the purchase has been renewed by the founding in issue #307. I've decided to redesign the Purchase Flow to not rely on Promise or Callback. There are some reasons not to approach in this way:

There may be more than one response when requesting a payment.
Purchases are inter-session asynchronuous meaning requests that are made may take several hours to complete and continue to exist even after the app has been closed or crashed.
The purchase may be pending and hard to track what has been done (example).
Thus the Billing Flow is an event pattern rather than a callback pattern.

Once you have called getProducts(), and you have a valid response, you can call requestPurchase(). Subscribable products can be purchased just like consumable products and users can cancel subscriptions by using the iOS System Settings.

Before you request any purchase, you should set purchaseUpdatedListener from react-native-iap. It is recommended that you start listening to updates as soon as your application launches. And don't forget that even at launch you may receive successful purchases that either completed while your app was closed or that failed to be finished, consumed or acknowledged due to network errors or bugs.

import RNIap, {
  purchaseErrorListener,
  purchaseUpdatedListener,
  type ProductPurchase,
  type PurchaseError
} from 'react-native-iap';

class RootComponent extends Component<*> {
  purchaseUpdateSubscription = null
  purchaseErrorSubscription = null

  componentDidMount() {
    this.purchaseUpdateSubscription = purchaseUpdatedListener((purchase: InAppPurchase | SubscriptionPurchase | ProductPurchase ) => {
      console.log('purchaseUpdatedListener', purchase);
      const receipt = purchase.transactionReceipt;
      if (receipt) {
        yourAPI.deliverOrDownloadFancyInAppPurchase(purchase.transactionReceipt)
        .then( async (deliveryResult) => {
          if (isSuccess(deliveryResult)) {
            // Tell the store that you have delivered what has been paid for.
            // Failure to do this will result in the purchase being refunded on Android and
            // the purchase event will reappear on every relaunch of the app until you succeed
            // in doing the below. It will also be impossible for the user to purchase consumables
            // again until you do this.
            if (Platform.OS === 'ios') {
              await RNIap.finishTransactionIOS(purchase.transactionId);
            } else if (Platform.OS === 'android') {
              // If consumable (can be purchased again)
              await RNIap.consumePurchaseAndroid(purchase.purchaseToken);
              // If not consumable
              await RNIap.acknowledgePurchaseAndroid(purchase.purchaseToken);
            }

            // From react-native-iap@4.1.0 you can simplify above `method`. Try to wrap the statement with `try` and `catch` to also grab the `error` message.
            // If consumable (can be purchased again)
            await RNIap.finishTransaction(purchase, true);
            // If not consumable
            await RNIap.finishTransaction(purchase, false);
          } else {
            // Retry / conclude the purchase is fraudulent, etc...
          }
        });
      }
    });

    this.purchaseErrorSubscription = purchaseErrorListener((error: PurchaseError) => {
      console.warn('purchaseErrorListener', error);
    });
  }

  componentWillUnmount() {
    if (this.purchaseUpdateSubscription) {
      this.purchaseUpdateSubscription.remove();
      this.purchaseUpdateSubscription = null;
    }
    if (this.purchaseErrorSubscription) {
      this.purchaseErrorSubscription.remove();
      this.purchaseErrorSubscription = null;
    }
  }
}

Then define the method like below and call it when user press the button.

  requestPurchase = async (sku: string) => {
    try {
      await RNIap.requestPurchase(sku, false);
    } catch (err) {
      console.warn(err.code, err.message);
    }
  }

  requestSubscription = async (sku: string) => {
    try {
      await RNIap.requestSubscription(sku);
    } catch (err) {
      console.warn(err.code, err.message);
    }
  }

  render() {
    ...
      onPress={() => this.requestPurchase(product.productId)}
    ...
  }

New Purchase Flow

Most likely, you'll want to handle the “store kit flow”^[2], which happens when a user successfully pays after solving a problem with his or her account – for example, when the credit card information has expired.

For above reason, we decided to remove ~~buyProduct~~ and use requestPurchase instead which doesn't rely on promise function. The purchaseUpdatedListener will receive the success purchase and purchaseErrorListener will receive all the failure result that occured during the purchase attempt.

Finishing a Purchase

Purchases will keep being emitted to your purchaseUpdatedListener on every app relaunch until you finish the purchase.

Consumable purchases should be consumed by calling consumePurchaseAndroid() or finishTransactionIOS(). Once an item is consumed, it will be removed from getAvailablePurchases() so it is up to you to record the purchase into your database before calling consumePurchaseAndroid() or finishTransactionIOS().

Non-consumable purchases need to be acknowledged on Android, or they will be automatically refunded after a few days. Acknowledge a purchase when you have delivered it to your user by calling acknowledgePurchaseAndroid(). On iOS non-consumable purchases are finished automatically but this will change in the future so it is recommended that you prepare by simply calling finishTransactionIOS() on non-consumables as well.

finishTransaction() works for both platforms and is recommended since version 4.1.0 or later. Equal to finishTransactionIOS + consumePurchaseAndroid and acknowledgePurchaseAndroid.

Restoring Purchases

You can use getAvailablePurchases() to do what's commonly understood as “restoring” purchases.

If for debugging you want to consume all items, you have to iterate over the purchases returned by getAvailablePurchases(). Beware that if you consume an item without having recorded the purchase in your database the user may have paid for something without getting it delivered and you will have no way to recover the receipt to validate and restore their purchase.

  getPurchases = async () => {
    try {
      const purchases = await RNIap.getAvailablePurchases();
      const newState = { premium: false, ads: true }
      let restoredTitles = [];

      purchases.forEach(purchase => {
        switch (purchase.productId) {
        case 'com.example.premium':
          newState.premium = true
          restoredTitles.push('Premium Version');
          break

        case 'com.example.no_ads':
          newState.ads = false
          restoredTitles.push('No Ads');
          break

        case 'com.example.coins100':
          await RNIap.consumePurchaseAndroid(purchase.purchaseToken);
          CoinStore.addCoins(100);
        }
      })

      Alert.alert('Restore Successful', 'You successfully restored the following purchases: ' + restoredTitles.join(', '));
    } catch(err) {
      console.warn(err); // standardized err.code and err.message available
      Alert.alert(err.message);
    }
  }

Returned purchases is an array of each purchase transaction with the following keys:

typeof `AvailablePurchase`

Property	Type	iOS	And	Comment
`productId`	`string`	✓	✓	The product ID for the product.
`transactionReceipt`	`string`	✓	✓	iOS: The `receipt`. Android: Stringified JSON of the original purchase object.
`transactionId`	`string`	✓	✓	A unique order identifier for the transaction.
`transactionDate`	`number`	✓	✓	The time the product was purchased, in milliseconds since the epoch (Jan 1, 1970).
`originalTransactionDateIOS`	`number`	✓		For a transaction that restores a previous transaction, the date of the original transaction.
`originalTransactionIdentifierIOS`	`string`	✓		For a transaction that restores a previous transaction, the transaction identifier of the original transaction.
`purchaseToken`	`string`		✓	A token that uniquely identifies a purchase for a given item and user pair.
`autoRenewingAndroid`	`boolean`		✓	Indicates whether the subscription renews automatically. If true, the subscription is active, and will automatically renew on the next billing date. Otherwise, indicates that the user has canceled the subscription.
`dataAndroid`	`string`		✓	Original json for purchase data.
`signatureAndroid`	`string`		✓	The signature of the purchase data that was signed with the private key of the developer. The data signature uses the `RSASSA-PKCS1-v1_5` scheme.
`isAcknowledgedAndroid`	`boolean`		✓	Checking if purchase has been acknowledged.
`purchaseStateAndroid`	`number`		✓	Indicating purchase state.

You need to test with one sandbox account, because the account holds previous purchase history.

Receipt validation

Since react-native-iap@0.3.16, we support receipt validation.

With IAPHUB

IAPHUB is a service that takes care of the ios/android receipt validation for you, you can set up webhooks in order to get notifications delivered automatically to your server on events such as a purchase, a subscription renewal...

You can use it by calling the API manually to process your receipt or use the react-native-iaphub module that is just a wrapper of react-native-iap with IAPHUB built-in.

With Google Play

For Android, you need separate json file from the service account to get the access_token from google-apis, therefore it is impossible to implement serverless.

You should have your own backend and get access_token. With access_token you can simply call validateReceiptAndroid() we implemented. Further reading is here or refer to example repo.

With App Store

Currently, serverless receipt validation is possible using validateReceiptIos().

The first parameter, you should pass transactionReceipt which returns after buyProduct().
The second parameter, you should pass whether this is test environment. If true, it will request to sandbox and false it will request to production.

  const receiptBody = {
    'receipt-data': purchase.transactionReceipt,
    'password': '******'
  };
  const result = await RNIap.validateReceiptIos(receiptBody, false);
  console.log(result);

For further information, please refer to guide.

Sometimes you will need to get the receipt at times other than after purchase. For example, when a user needs to ask for permission to buy a product (Ask to buy flow) or unstable internet connections.

For these cases we have a convenience method getReceiptIOS() which gets the latest receipt for the app at any given time. The response is base64 encoded.

iOS Purchasing process right way.

Issue regarding valid products

In iOS, generally you are fetching valid products at App launching process.

If you fetch again, or fetch valid subscription, the products are added to the array object in iOS side (Objective-C NSMutableArray).

This makes unexpected behavior when you fetch with a part of product lists.

For example, if you have products of [A, B, C], and you call fetch function with only [A], this module returns [A, B, C]).

This is weird, but it works.
But, weird result is weird, so we made a new method which remove all valid products.

If you need to clear all products, subscriptions in that array, just call clearProductsIOS(), and do the fetching job again, and you will receive what you expected.

Example backend (Node.js)

Here you can find an example backend for idempotent validating of receipts on both iOS/Android and storing and serving subscription state to the client.

Q & A

How can a user cancel a subscription in my app?

For both iOS and Android your users cannot cancel subscriptions inside your app. You need to direct your users to iTunes/the App Store or Google Play.
You can do this on iOS 12 or later (for earlier iOS versions, use this URL):
```
Linking.openURL('https://apps.apple.com/account/subscriptions')
```

You can do this on Android:

Linking.openURL('https://play.google.com/store/account/subscriptions?package=YOUR_PACKAGE_NAME&sku=YOUR_PRODUCT_ID

(change YOUR_PACKAGE_NAME and YOUR_PRODUCT_ID)

More on Linking in React Native: https://facebook.github.io/react-native/docs/linking

Can I buy product right away skipping fetching products if I already know productId?

You could only in Android in react-native-iap@^2.*.

However, now you should always fetchProducts first in both platforms. It is because Android BillingClient has been updated billingFlowParams to include SkuDetails instead sku string which is hard to share between react-native and android.

It happened since com.android.billingclient:billing:2.0.*.

Therefore we've planned to store items to be fetched in Android before requesting purchase from react-native side, and you should always fetch list of items to “purchase” before requesting purchase.

How do I handle promoted products in iOS?

Offical doc is here.
No initial setup needed from 4.4.5.

Add an EventListener for the iap-promoted-product event somewhere early in your app's lifecycle:

import { NativeModules, NativeEventEmitter } from 'react-native'
const { RNIapIos } = NativeModules;
const IAPEmitter = new NativeEventEmitter(RNIapIos);

IAPEmitter.addListener('iap-promoted-product', async () => {
  // Check if there's a persisted promoted product
  const productId = await RNIap.getPromotedProductIOS();
  if (productId !== null) { // You may want to validate the product ID against your own SKUs
    try {
      await RNIap.buyPromotedProductIOS(); // This will trigger the App Store purchase process
    } catch(error) {
      console.warn(error);
    }
  }
});

Invalid productId in iOS.

Please try below and make sure you've done the steps:
1. Completed an effective "Agreements, Tax, and Banking."
2. Setup sandbox testing account in "Users and Roles."
3. Signed into iOS device with sandbox account in "Settings / iTunes & App Stores".
4. Set up three In-App Purchases with the following status:
  - Ready to Submit

Module is not working as expected. Throws error.

`getAvailablePurchases()` returns empty array.

getAvailablePurchases() is used only when you purchase a non-consumable product. This can be restored only.

If you want to find out if a user subscribes the product, you should check the receipt which you should store in your own database.

Apple suggests you handle this in your own backend to do things like what you are trying to achieve.

Using Face ID & Touch to checkout on iOS

After you have completed the setup and set your deployment target to iOS 12, FaceID and Touch to purchase will be activated by default in production.

Please note that in development or TestFlight, it will NOT use FaceID/Touch to checkout because they are using the Sandbox environment.

Supporting react-native-iap

react-native is an open source project with MIT license. We are willing to maintain this repository to support devs to monetize around the world.

Since IAP itself is not perfect on each platform, we desperately need this project to be maintained. If you'd like to help us, please consider being with us in Open Collective.
