Announcement

React Native IAP hook is out. You can see medium post on how to use it.

The react-native-iap module hasn't been maintained well recently. We are thinking of participating again and make the module healthier. Please refer to 2021 Maintenance plan and share with us how you or your organization is using it. Happy new year 🎉

  • The sample code is out in Sponsor page in dooboolab.com repository which sadly is rejected by Apple because of lacking product features. I will work on another example project to support this module. More information in #1241 commment.

Introduction

This react-native module will help you access the In-app purchases capabilities of your phone on the Android, iOS platforms and the Amazon platform (Beta).

Keep in mind react-native-iap will provide the basic features you need but is not a turnkey solution, implementing In-app purchases in your app will still require quite some work.
Also, implementing the client side is only one side of the coin, you'll have to implement the server side to validate your receipts (which is probably the most time consuming part to do it correctly).

If you're looking for a module going further than react-native-iap, we recommend using react-native-iaphub which is taking care of everything from the client side to the server side.

⚠️ Most of users experiencing issues are caused by:

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.
  • 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.
    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

  • Please refer to Blog.

Deprecated README

  • If you are using react-native-iap@^2.*, please follow the above README.

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.

    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

    Migrating to 3.4.0

    • Upgrade to the new purchase flow.
    • 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 product IDs for iOS and Android separately like defined below.

    import * as RNIap from 'react-native-iap';
    
    const productIds = 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(productIds);
          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.
    countryCode Returns the store country 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.
    introductoryPriceAsAmountAndroid Localized introductory price string, with only number (eg. 0.99).
    introductoryPriceAsAmountIOS Localized introductory price string, with only number (eg. 0.99).
    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:

    1. There may be more than one response when requesting a payment.
    2. 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.
    3. The purchase may be pending and hard to track what has been done (example).
    4. 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() {
        RNIap.initConnection().then(() => {
          // we make sure that "ghost" pending payment are removed
          // (ghost = failed pending payment that are still marked as pending in Google's native Vending module cache)
          RNIap.flushFailedPurchasesCachedAsPendingAndroid().catch(() => {
            // exception can happen here if:
            // - there are pending purchases that are still pending (we can't consume a pending purchase)
            // in any case, you might not want to do anything special with the error
          }).then(() => {
            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

    purchase-flow-sequence

    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.
    packageNameAndroid string Get package name.
    developerPayloadAndroid string https://developer.android.com/google/play/billing/developer-payload
    obfuscatedAccountIdAndroid string https://developer.android.com/reference/com/android/billingclient/api/BillingFlowParams.Builder#setobfuscatedaccountidBuilder#setobfuscatedaccountId
    obfuscatedProfileIdAndroid string https://developer.android.com/reference/com/android/billingclient/api/BillingFlowParams.Builder#setobfuscatedprofileid

    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

    getProducts returns empty array

    • Please double check if you've called initConnection.
    • Please wait for max 24 hours to fetch your iap products if you've just uploaded them. Related to issue.
    • For iOS, from ios version >=13, we seem to use StoreKit to fix this issue as mentioned in stackoverflow.
    • For android, please double check issue comment here and see if you've missed something.

    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 validate receipt in iOS?

    How do I validate receipt in Android?

    • Offical doc is here.

    • I've developed this feature for other developers to contribute easily who are aware of these things. The doc says you can also get the accessToken via play console without any of your backend server.

      You can get this by following process:

      • Open Google Play Console > Select your app > Development tools > Services & APIs > Find in “Your license key for this application”. reference.

    How to make consumable product in Android developer mode?

    • If you are facing "You already own this item" on developer(test) mode, you might check related issue #126

    How do I use react-native-iap in Expo?

    • You should detach from expo and get expokit out of it.
    • Releated issue in #174.

    How do I handle promoted products in iOS?

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

    Somewhere early in your app's lifecycle, call initConnection first (see above), then add a listener for the iap-promoted-product event:

    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
        • Missing Metadata
        • Waiting for Review
      5. Enable "In-App Purchase" in Xcode "Capabilities" and in Apple Developer -> "App ID" setting.
      6. Clean up builds:
        • Delete the app on device
        • Restart device
        • Quit “store” related processes in Activity Monitor
        • Development Provisioning Profile -> Clean -> Build.
    • Related issues #256 , #263.

    Module is not working as expected. Throws error.

    • The react-native link script isn't perfect and sometimes broke. Please try unlink and link again, or try manual install.

    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.
