react-native-iap

This is a react-native link 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 platform and will continuously merge methods which are standing alone.

Android iap is implemented with iap version 3 which is currently recent.

Playstore & Itunnesconnect configuration

Please refer to Blog.

Important

Do not use version 0.3.4 ~ 0.3.8 because there was some issues in merging PR. Also please commit to dev branch and not master branch please if requesting PR. react-native-iap module versions that are not described in change logs may not run as expected so please refer to version mentioned in Changelogs below.

Migration Guide

Difference between 0.3.* and 1.0.0 has only one method renaming refreshItems to consumeAllItems.

To migrate 0.2.* to 0.3.*, You can follow below guide.

0.2.*	0.3.*
`prepareAndroid`	`prepare`
`getItems`	`getProducts`
`getSubscribeItems`	`getSubscriptions`
`getPurchasedItemsAndroid`	`getPurchaseHistory`
``	`getAvailablePurchases`
`buySubscribeItem`	`buySubscription`
`buyItem`	`buyProduct`
`consumeItemAndroid`	`consumePurchase`
`refreshAllItems`	Not Available
`refreshPurchaseItemsAndroid`	Not Available

From above method changes, getProducts gets itemSkus as parameter in different way then as used in getItems. In getItems you had to put parameter as

const itemSkus = {
  ios: [
	'point_1000',
  ],
  android: [
    'point_1000',
  ],
};

But now you should do like below which will just pass single array instead of object.

const itemSkus = Platform.select({
  ios: [
	'point_1000',
  ],
  android: [
    'point_1000',
  ],
});

Also, note that this is our last migration for renaming method names without any deprecation warning. Thank you for your understanding.

Breaking Changes

0.3.0-alpha1 has released. All the methods are renamed and current methods are merged into each single method. See Methods section below to see what's been changed.

Breaking changes have made from 0.2.17. refreshAllItems has changed name to fetchHistory. See the changelogs below.

Breaking changes have made from 0.2.16 in android. Package name has been fixed to com.dooboolab.RNIap.RNIapPackage. Read the changelogs below. There was linking issue with wrong package name.

Breaking changes have made from 0.2.12. Please read the changelogs below. The summary of change is that it now returns receipt in different format.

Changes from react-native-iap@0.1.* to react-native-iap@0.2.* is that you have prepare() method deprecated which you should call before using RNIap methods. Now you have to call prepareAndroid() instead just to know that it is just android dependent method. Also to import module, previously in react-native-iap@0.1.* you had to import RNIap from 'react-native-iap' but now you have to do like import * as RNIap from 'react-native-iap'.

For new method, refreshAllItems has been implemented for both ios and android. This feature will support senario for non-consumable products. Also there are some other methods that is not supported in ios and implemented in android. You can see more in Changelogs below. Lastly, this module also supports types for typescript users from 0.2.5.

Changelogs

Methods

Func	Param	Return	Description
prepare		`Promise<void>`	Prepare IAP module. Must be called on Android before any other purchase flow methods. No-op on iOS.
getProducts	`string[]` Product IDs/skus	`Promise<Product[]>`	Get a list of products (consumable and non-consumable items, but not subscriptions). Note: On iOS versions earlier than 11.2 this method will return subscriptions if they are included in your list of SKUs. This is because we cannot differentiate between IAP products and subscriptions prior to 11.2.
getSubscriptions	`string[]` Subscription IDs/skus	`Promise<Subscription[]>`	Get a list of subscriptions. Note: On iOS this method has the same output as `getProducts`. Because iOS does not differentiate between IAP products and subscriptions.
getPurchaseHistory		`Promise<Purchase[]>`	Gets an invetory 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)
buySubscription	`string` Subscription ID/sku	`Promise<Purchase>`	Create (buy) a subscription to a sku
buyProduct	`string` Product ID/sku	`Promise<Purchase>`	Buy a product
buyProductWithoutFinishTransaction	`string` Product ID/sku	`Promise<Purchase>`	Buy a product without finish transaction call (iOS only)
finishTransaction	`void`	`void`	Send finishTransaction call to Apple IAP server. Call this function after receipt validation process
consumeProduct	`string` Purchase token	`Promise<void>`	Consume a product (on Android.) No-op on iOS.
endConnection		`Promise<void>`	End billing connection (on Android.) No-op on iOS.
consumeAllItems		`Promise<void>`	Consume all items in android so they are able to buy again (on Android.) No-op on iOS.
validateReceiptIos	`object` receiptBody, `boolean` isTest, `number` RNVersion	`object or boolean` result	validate receipt for ios.
validateReceiptAndroid	`string` packageName, `string` productId, `string` productToken, `string` accessToken, `boolean` isSubscription, `number` RNVersion	`object or boolean` result	validate receipt for android.

Note for Ejected iOS Apps:

The above command will add the following to your Podfile:

pod 'RNIap', :path => '../node_modules/react-native-iap'

You should remove this before running pod install and follow the manual installation instructions below.

Manual installation

iOS

In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
Go to node_modules ➜ react-native-iap and add RNIap.xcodeproj
In XCode, in the project navigator, select your project. Add libRNIap.a to your project's Build Phases ➜ Link Binary With Libraries
Run your project (Cmd+R)<

Android

Open up android/app/src/main/java/[...]/MainApplication.java

Add import com.dooboolab.RNIap.RNIapPackage; to the imports at the top of the file
Add new RNIapPackage() to the list returned by the getPackages() method

Append the following lines to android/settings.gradle:

include ':react-native-iap'
project(':react-native-iap').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-iap/android')

Insert the following lines inside the dependencies block in android/app/build.gradle:
```
  compile project(':react-native-iap')
```
Add the following to the <permission> block in android/app/src/main/AndroidManifest.xml:
```
<uses-permission android:name="com.android.vending.BILLING" />
```

Usage

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

Prepare 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'
  ]
});

Next, call the prepare function (ios it's not needed, but android it is. No need to check platform though since nothing will happen in ios:

async function() {
  try {
    await RNIap.prepare();
    // Ready to call RNIap.getProducts(), etc.
  } catch(err) {
    console.warn(err); // standardized err.code and err.message available
  }
}

Get Valid Items

Once you called prepare(), call getProducts(). Both are async funcs. You can do it in componentDidMount(), or other 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 the your IAP store.

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

Each item is a JavaScript object containing these keys:

	iOS	Android	Comment
`price`	✓	✓	Will return localizedPrice on Android (default) or a string price (eg. `1.99`) (iOS)
`productId`	✓	✓	Returns a string needed to purchase the item later
`currency`	✓	✓	Returns the currency code
`localizedPrice`	✓	✓	Use localizedPrice if you want to display the price to the user so you don't need to worry about currency symbols.
`title`	✓	✓	Returns the title Android and localizedTitle on iOS
`description`	✓	✓	Returns the description of the product
`type`	✓	✓	Returns SKU type (subscription or in-app product). iOS < 11.2 will always return `null`

End Billing Connection

When you are done with the billing, you should release it for android(READ). It is not needed in ios. No need to check platform either since nothing will happen in ios. This can be used in componentWillUnMount.

Purchase

Once you have called getProducts(), and you have a valid response, you can call buyProduct().

  // Will return a purchase object with a receipt which can be used to validate on your server.
  const purchase = await RNIap.buyProduct('com.example.coins100');

In RNIapExample, upon receiving receiving a purchase receipt, main page will navigate to Second.js.

Purchase Example 2 (Advanced)

this.setState({ progressTitle: 'Please wait...' });
RNIap.buyProduct('com.example.coins100').then(purchase => {
    this.setState({
      receipt: purchase.transactionReceipt, // save the receipt if you need it, whether locally, or to your server.
      progressTitle: 'Purchase Successful!',
      coins: this.state.coins + 100
    });
  }).catch(err => {
    // resetting UI
    console.warn(err); // standardized err.code and err.message available
    this.setState({ progressTitle: 'Buy 100 Coins for only $0.99' });
    alert(err.message);
  })

Subscribable products can be purchased just like consumable products. Users can cancel subscriptions by using the iOS System Settings.

Consumption and Restoring Purchases

You can use getAvailablePurchases() to do what's commonly understood as "restoring" purchases. Once an item is consumed, it will no longer be available in getAvailablePurchases() and will only be available via getPurchaseHistory(). However, this method has some caveats on Android -- namely that purchase history only exists for the single most recent purchase of each SKU -- so your best bet is to track consumption in your app yourself. By default all items that are purchased will not be consumed unless they are automatically consumed by the store (for example, if you create a consumable item for iOS.) This means that you must manage consumption yourself. Purchases can be consumed by calling consumePurchase(). If you want to consume all items, you have to iterate over the purchases returned by getAvailablePurchases().

getPurchases = async() => {
  try {
    const purchases = await RNIap.getAvailablePurchases();
    let restoredTitles = '';
    let coins = CoinStore.getCount();
    purchases.forEach(purchase => {
      if (purchase.productId == 'com.example.premium') {
        this.setState({ premium: true });
        restoredTitles += 'Premium Version';
      } else if (purchase.productId == 'com.example.no_ads') {
        this.setState({ ads: false });
        restoredTitles += restoredTitles.length > 0 ? 'No Ads' : ', No Ads';
      } else if (purchase.productId == 'com.example.coins100') {
        CoinStore.addCoins(100);
        await RNIap.consumePurchase(purchase.purchaseToken);
      }
    })
    Alert.alert('Restore Successful', 'You successfully restored the following purchases: ' + restoredTitles);
  } 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:

{
  transactionDate,
  transactionId,
  productId,
  transactionReceipt,
  purchaseToken, // available on Android (same as transactionReceipt)
  autoRenewing, // available on Android
  originalTransactionDate, // available on iOS
  originalTransactionIdentifier // available on iOS
}

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

Receipt validation

From react-native-iap@0.3.16, we support receipt validation. For android, you need seperate json file from service account to get the access_token from google-apis, therefore it is impossible to implement serverlessly. You should have your own backend and get access_token. With access_token you can simplly call validateReceiptAndroid method we implemented. Further reading is here.

Currently, serverless receipt validation is possible using validateReceiptIos method. First parameter, you should pass transactionReceipt which returns after buyProduct. 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,
};
const result = await validateReceiptIos(receiptBody, false, 54);
console.log(result);

For further information, please refer to guide.

iOS Purchasing process right way.

Purchasing consumable products in iOS consists of the following steps.

Step 1 : Purchasing via IAP (Apple server)
Step 2 : Check the validation of the receipt (either on device or server)
Step 3 : Apply the product to the Application

But, sometimes app doesn't make it to step 3, and user loose the product with successful payment. Non-consumable products can be restored via getPurchaseHistory function, but consumable products can be lost. In this case, use buyProductWithoutFinishTransaction to purchase action and use finishTransaction to finish payment after receipt validation and supply the products to user.
