react-native-in-app-utils

A react-native wrapper for handling in-app purchases.

Notes

  • You need an Apple Developer account to use in-app purchases.

  • You have to set up your in-app purchases in iTunes Connect first. Follow this tutorial for an easy explanation.

  • You have to test your in-app purchases on a real device, in-app purchases will always fail on the Simulator.

Add it to your project

  1. Make sure you have rnpm installed: npm install rnpm -g

  2. Install with rnpm: rnpm install react-native-in-app-utils

  3. Whenever you want to use it within React code now you just have to do: var InAppUtils = require('NativeModules').InAppUtils; or for ES6:

    import { NativeModules } from 'react-native'
import { InAppUtils } from 'NativeModules'

API

Loading products

You have to load the products first to get the correctly internationalized name and price in the correct currency.

var products = [
   'com.xyz.abc',
];
InAppUtils.loadProducts(products, (error, products) => {
   //update store here.
});

Response fields:

Field Type Description
identifier string The product identifier
price number The price as a number
currencySymbol string The currency symbol, i.e. "$" or "SEK"
currencyCode string The currency code, i.e. "USD" of "SEK"
priceString string Localised string of price, i.e. "$1,234.00"
downloadable boolean Whether the purchase is downloadable
description string Description string
title string Title string

Troubleshooting: If you do not get back your product(s) then there's a good chance that something in your iTunes Connect or Xcode is not properly configured. Take a look at this StackOverflow Answer to determine what might be the issue(s).

Buy product

var productIdentifier = 'com.xyz.abc';
InAppUtils.purchaseProduct(productIdentifier, (error, response) => {
   // NOTE for v3.0: User can cancel the payment which will be availble as error object here.
   if(response && response.productIdentifier) {
      AlertIOS.alert('Purchase Successful', 'Your Transaction ID is ' + response.transactionIdentifier);
      //unlock store here.
   }
});

NOTE: Call loadProducts prior to calling purchaseProduct, otherwise this will return invalid_product. If you're calling them right after each other, you will need to call purchaseProduct inside of the loadProducts callback to ensure it has had a chance to complete its call.

Response fields:

Field Type Description
transactionIdentifier string The transaction identifier
productIdentifier string The product identifier

Restore payments

InAppUtils.restorePurchases((error, response)=> {
   if(error) {
      AlertIOS.alert('itunes Error', 'Could not connect to itunes store.');
   } else {
      AlertIOS.alert('Restore Successful', 'Successfully restores all your purchases.');
      //unlock store here again.
   }
});

Response: An array of transactions with the following fields:

Field Type Description
originalTransactionIdentifier string The original transaction identifier
transactionIdentifier string The transaction identifier
productIdentifier string The product identifier

Receipts

iTunes receipts are associated to the users iTunes account and can be retrieved without any product reference.

InAppUtils.receiptData((error, receiptData)=> {
  if(error) {
    AlertIOS.alert('itunes Error', 'Receipt not found.');
  } else {
    //send to validation server
  }
});

Response: The receipt as a base64 encoded string.

Testing

To test your in-app purchases, you have to run the app on an actual device. Using the iOS Simulator, they will always fail as the simulator cannot connect to the iTunes Store. However, you can do certain tasks like using loadProducts without the need to run on a real device.

  1. Set up a test account ("Sandbox Tester") in iTunes Connect. See the official documentation here.

  2. Run your app on an actual iOS device. To do so, first run the react-native server on the local network instead of localhost. Then connect your iDevice to your Mac via USB and select it from the list of available devices and simulators in the very top bar. (Next to the build and stop buttons)

  3. Open the app and buy something with your Sandbox Tester Apple Account!
