iaphub / React Native Iaphub

Implementing and developping all the tools to manage your In-App purchases properly can be very complex and time consuming. You should spend this precious time building your app!

IAPHUB has all the features you need to increase your sales 🚀

Getting started

Implementing In-app purchases in your app should be a piece of cake!
This module implements the IAPHUB API on top of the react-native-iap module 👏

1. Create an account on IAPHUB

2. Install the package

// Install react-native-iap which is a required peer dependency (Be sure you install version 5.1.1)
npm install react-native-iap@5.1.1 --save-exact
// Install react-native-iaphub
npm install react-native-iaphub --save
// Update dependency on xcode (in the ios folder)
pod install

Init

Call the init method at the start of your app to initialize your configuration

ℹ️ It should be called as soon as possible when starting your app.

  await Iaphub.init({
    // The app id is available on the settings page of your app
    appId: "5e4890f6c61fc971cf46db4d",
    // The (client) api key is available on the settings page of your app
    apiKey: "SDp7aY220RtzZrsvRpp4BGFm6qZqNkNf",
    // App environment (production by default, other environments must be created on the IAPHUB dashboard)
    environment: "production"
  });

Set user id

Call the setUserId method to authenticate an user.

If you have an authentication system, provide the user id of the user right after the user log in.
If you don't and want to handle IAP on the client side, you can provide the device id when the app start instead by using a module such as react-native-device-info to get a device unique ID.

⚠ You should provide an id that is non-guessable and isn't public. (Email not allowed)

await Iaphub.setUserId("1e5494930c48ed07aa275fd2");

Set user tags

Call the setUserTags method to update the user tags.
User tags will appear on the user page of the IAPHUB dashboard.
When using IAPHUB's smart listings, you'll be able to return different products depending on the user tags.

// To set a tag
await Iaphub.setUserTags({status: 'vip'});
// To clear the user tags
await Iaphub.setUserTags({status: null});

A few details:

• A tag must be created on the IAPHUB dashboard (otherwise the method will throw an error)
• When creating a tag on the IAPHUB dashboard you must check the option to allow editing the tag from the client (otherwise you'll only be able to edit the tag using the IAPHUB API from your server)
• A tag key is limited to 32 characters
• A tag value is limited to 64 characters

Set device params

Call the setDeviceParams method to set parameters for the device
When using IAPHUB's smart listings, you'll be able to return different products depending on the device params.

// For instance you can provide the app version on app launch
// Useful to return a product only supported in a new version
Iaphub.setDeviceParams({appVersion: '1.2.0'});
// To clear the device params
Iaphub.setDeviceParams({});

A few details:

• The params are not saved on the device, they won't persist if the app is restarted
• The params are not saved on IAPHUB, they are just provided to the API when fetching the products for sale
• A param key limited to 32 characters and must be a valid key (^[a-zA-Z_]*$)
• A param value limited to 32 characters
• You can provide up to 5 params

Get products for sale

Call the getProductsForSale method to get the user's products for sale
You should use this method when displaying the page with the list of your products for sale.

⚠ If the request fails because of a network issue, the method returns the latest request in cache (if available, otherwise an error is thrown).

⚠ If a product is returned by the API but the sku cannot be loaded, it'll be filtered from the list and an error message will be displayed in the console

var products = await Iaphub.getProductsForSale();

console.log(products);
[
  {
    id: "5e5198930c48ed07aa275fd9",
    type: "renewable_subscription",
    sku: "membership2_tier10",
    group: "3e5198930c48ed07aa275fd8",
    groupName: "subscription_group_1",
    title: "Membership",
    description: "Become a member of the community",
    price: "$9.99",
    priceAmount: 9.99,
    priceCurrency: "USD",
    subscriptionPeriodType: "normal",
    subscriptionDuration: "P1M"
  },
  {
    id: "5e5198930c48ed07aa275fd9",
    type: "consumable",
    sku: "pack10_tier15",
    title: "Pack 10",
    description: "Pack of 10 coins",
    price: "$14.99",
    priceAmount: 14.99,
    priceCurrency: "USD"
  }
]

Product properties

Get active products

If you're relying on IAPHUB on the client side (instead of using your server with webhooks) to detect if the user has active products (auto-renewable subscriptions, non-renewing subscriptions or non-consumables), you should use the getActiveProducts method when the app is brought to the foreground.

⚠ If the request fails because of a network issue, the method returns the latest request in cache (if available with no expired subscription, otherwise an error is thrown).

⚠ If an active product is returned by the API but the sku cannot be loaded, the product will be returned but only with the properties coming from the API (The price, title, description.... properties won't be returned).

class App extends Component {

  state = {
    appState: AppState.currentState
  };

  componentDidMount() {
    AppState.addEventListener("change", this.handleAppStateChange);
  }

  componentWillUnmount() {
    AppState.removeEventListener("change", this.handleAppStateChange);
  }

  handleAppStateChange = (nextAppState) => {
    if (
      this.state.appState.match(/inactive|background/) &&
      nextAppState === "active"
    ) {
      var products = await Iaphub.getActiveProducts();
      
      console.log(products);
      [{
        id: "5e5198930c48ed07aa275fd9",
        type: "renewable_subscription",
        sku: "membership1_tier5",
        purchase: "5e5198930c48ed07aa275fe8",
        purchaseDate: "2020-03-11T00:42:28.000Z",
        expirationDate: "2021-03-11T00:42:28.000Z",
        isSubscriptionRenewable: true,
        group: "3e5198930c48ed07aa275fd8",
        groupName: "subscription_group_1",
        title: "Membership",
        description: "Become a member of the community",
        price: "$4.99",
        priceAmount: 4.99,
        priceCurrency: "USD",
        subscriptionState: 'active',
        subscriptionDuration: "P1M",
        subscriptionPeriodType: "intro",
        subscriptionIntroPrice: "$1.99",
        subscriptionIntroPriceAmount: 1.99,
        subscriptionIntroPayment: "as_you_go",
        subscriptionIntroDuration: "P1M",
        subscriptionIntroCycles: 3
      }]
    }
    this.setState({ appState: nextAppState });
  };

  render() {
    return (
      <View>
        <Text>My app</Text>
      </View>
    );
  }
}

Subscription state

By default only subscriptions with an active or grace_period state are returned by the getActiveProducts() method because you must restrict the access to the features offered by your subscription on a retry_period or paused state.

If you're looking to display a message when a user has a subscription on a retry_period or paused state, you can use the includeSubscriptionStates option.

  var allActiveProducts = await iaphub.getActiveProducts({
    includeSubscriptionStates: ['retry_period', 'paused']
  });

Buy a product

Call the buy method to buy a product

ℹ️ The method needs the product sku that you would get from one of the products of getProductsForSale().
ℹ️ The method will process a purchase as a subscription replace if you currently have an active subscription and you buy a subscription of the same group (product group created on IAPHUB).

try {
  var transaction = await Iaphub.buy("pack10_tier15", {
    // Optional callback triggered before the receipt is processed
    onReceiptProcess: (receipt) => {
      console.log('Purchase success, processing receipt...');
    }
  });
  console.log(transaction);
  {
    id: "2e5198930c48ed07aa275fd3",
    type: "consumable",
    sku: "pack10_tier15",
    purchase: "4e5198930c48ed07aa275fd2",
    purchaseDate: "2020-03-11T00:42:27.000Z",
    webhookStatus: "success",
    group: "3e5198930c48ed07aa275fd8",
    groupName: "pack",
    title: "Pack 10",
    description: "Pack of 10 coins",
    price: "$14.99",
    priceAmount: 14.99,
    priceCurrency: "USD"
  }

  /*
   * The purchase has been successful but we need to check that the webhook to our server was successful as well
   * If the webhook request failed, IAPHUB will send you an alert and retry again in 1 minute, 10 minutes, 1 hour and 24 hours.
   * You can retry the webhook directly from the dashboard as well
   */
  if (transaction.webhookStatus == "failed") {
    Alert.alert(
      "Purchase delayed",
      "Your purchase was successful but we need some more time to validate it, should arrive soon! Otherwise contact the support ([email protected])"
    );
  }
  // Everything was successful! Yay!
  else {
    Alert.alert(
      "Purchase successful",
      "Your purchase has been processed successfully!"
    );
  }
} catch (err) {
  // Purchase popup cancelled by the user (ios only)

    );
  }
  /*
   * The receipt has been processed on IAPHUB but something went wrong
   * It is probably because of an issue with the configuration of your app or a call to the Itunes/GooglePlay API that failed

   * After fixing the issue (if there's any), just click on the 'New report' button in order to process the receipt again

   */
  else if (err.code == "cross_platform_conflict") {
    Alert.alert(
      `Seems like you already have a subscription on ${err.params.platform}`,

    Alert.alert(

      "We were not able to process your purchase, please try again later or contact the support ([email protected])"
    );
  }
}

Proration mode (Android only)

You can specify the proration mode when replacing a subscription.

var transaction = await Iaphub.buy("membership_tier1", {
  prorationMode: 'immediate_and_charge_prorated_price'
});

Restore user purchases

Call the restore method to restore the user purchases

ℹ️ You should display a restore button somewhere in your app (usually on the settings page).
ℹ️ If you logged in using the device id, an user using a new device will have to restore its purchases since the device id will be different.

await Iaphub.restore();

FAQ

I'm already validating receipts on my server, can I run receipt validation on both my server and IAPHUB?

Yes! It can be pretty handy if you want to:

• Slowly migrate over IAPHUB
• Give IAPHUB a try without shutting down your current receipt validation system
• Implement a fallback system to validate receipts when an error occurs
• Run both systems in parallel

It's easy to implement by using the onReceiptProcessed event that is triggered after IAPHUB processed a receipt

  await Iaphub.init({
    appId: "5e4890f6c61fc971cf46db4d",
    apiKey: "SDp7aY220RtzZrsvRpp4BGFm6qZqNkNf",
    environment: "production"
    /*
     * Event triggered after IAPHUB processed a receipt
     * @param {Object} err Error object if the receipt processing failed (otherwise null)
     * @param {Object} receipt - Receipt object
     * @param {String} receipt.sku - Product sku
     * @param {String} receipt.token - Receipt token
     * @param {Boolean} receipt.isRestore - If the event is triggered from a restore
     */
    onReceiptProcessed: async (err, receipt) => {
      console.log(receipt);
      {
        sku: "pack10_tier15",
        token: "dzw4d....sd",
        isRestore: false
      }
      /*
       * Send the receipt to yout server
       * If you want to override the transaction returned by the buy method, your server must return the new transactions of the receipt
       * Warning: Do not return the old transactions already processed!
       */
      var newTransactions = await fetch("https://api.myapp.com/receipt", {
        method: "POST",
        headers: {'Accept': 'application/json', 'Content-Type': 'application/json'},
        body: JSON.stringify(receipt)
      });
      console.log(newTransactions);
      [{
        sku: "pack10_tier15"
      }]
      /*
       * If an array is returned by this function it'll override the receipt transactions returned by IAPHUB
       * For instance, below we only override the transactions if the receipt processing failed with an error
       * A transaction must contain at least the property 'sku' in order to identify the transaction that will be returned from the buy method
       */
      if (err) {
        return newTransactions;
      }
    }
  });
