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!

1. Create an account on IAPHUB

2. Install the package

// Install react-native-iaphub
npm install react-native-iaphub --save
// Update dependency on xcode (in the ios folder)
pod install

3. Make sure the In-App purchases capability of your ios project is enabled on XCode

4. Setup your sandbox environment (ios / android)

5. Read our complete guide to set up your app.

⚠ If you're migrating from v6.X.X to v7.X.X, read this.

Start

Call the start method in order to initialize IAPHUB.

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

  await Iaphub.start({
    // 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",
    // Optional, ff you want to allow purchases when the user has an anonymous user id
    // If you're listenning to IAPHUB webhooks your implementation must support users with anonymous user ids
    // This option is disabled by default, when disabled the buy method will return an error when the user isn't logged in
    allowAnonymousPurchase: true
    // -- OPTIONAL -- //
    // App environment (IAPHUB supports multiple environments, an environment act like a separate app and must be created on the IAPHUB dashboard)
    //environment: "staging"
  });

Events

Call the addEventListener method to listen to an event and removeEventListener to stop listening to an event.

onUserUpdate - Event triggered when the user products have been updated

  // Listen to the user update event in order to know when the activeProducts/productsForSale are updated
  var listener = Iaphub.addEventListener('onUserUpdate', async () => {
    // TODO here: Refresh the state of your products in order to refresh the screen
    // You can use the getActiveProducts/getProductsForSale methods to get the updated products
  });
  // You can also unlisten the event
  Iaphub.removeEventListener(listener);

onBuyRequest - Event triggered when a purchase intent is made from outside the app (like a promoted In-App purchase)

  // Add listener
  var listener = Iaphub.addEventListener('onBuyRequest', async (sku) => {
    // If you want to allow/disallow a purchase intent (to wait until the user is logged in for example) you can implement this method
    // You'll have to call the buy method whenever you're ready
    // Also note you'll have a callback to know when the transaction is done (you woudn't otherwise)
    var transaction = await Iaphub.buy(sku);
    console.log("Purchase done: ", transaction);
  });
  // Remove listener
  Iaphub.removeEventListener(listener);

onError - Event triggered when IAPHUB has detected an error

  // Add listener
  var listener = Iaphub.addEventListener('onError', async (err) => {
    // You'll catch any error here (even errors thrown by IAPHUB methods)
    console.log("Error: ", err.message);
  });
  // Remove listener
  Iaphub.removeEventListener(listener);

onReceipt - Event triggered after a receipt has been processed

  // Add listener
  var listener = Iaphub.addEventListener('onReceipt', async (data) => {
    console.log("Receipt err: ", data.err);
    console.log("Receipt data: ", err.receipt);
  });
  // Remove listener
  Iaphub.removeEventListener(listener);

ℹ️ You can also remove all the listeners by using the method removeAllListeners()

Login

Call the login method to authenticate a user.

⚠ When a user isn't logged he's considered anonymous, we'll generate automatically a anonymous user id (prefixed with 'a:')

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

⚠ The user will be reset, setOnUserUpdateListener will only be called until after the user has been loaded first (using getProductsForSale/getActiveProducts).

await Iaphub.login("1e5494930c48ed07aa275fd2");

Logout

Call the logout method to log the user out.
The user will switch back to his anonymous user id (prefixed with 'a:').

⚠ The user will be reset, setOnUserUpdateListener will only be called until after the user has been loaded first (using getProductsForSale/getActiveProducts).

Iaphub.logout()

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

⚠ If you have multiple Android offers, the oldest (first one you've created) will be used by default. We've decided to not support multiple Android offers in order to have a common system with iOS. To have a different offer simply create a new product, you can do pretty much everything with smart listings.

var products = await Iaphub.getProductsForSale();

console.log(products);
[
  {
    id: "5e5198930c48ed07aa275fd9",
    type: "renewable_subscription",
    sku: "membership2_tier10",

  }
]

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.

⚠ 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).

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']
  });

Get all products

You can also get the products for sale and active products using one method getProducts()

  var data = await Iaphub.getProducts();
  console.log("Products for sale: ", data.productsForSale);
  console.log("Active products: ", data.activeProducts);

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");
  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",
    localizedTitle: "Pack 10",
    localizedDescription: "Pack of 10 coins",
    localizedPrice: "$14.99",
    price: 14.99,
    currency: "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])"
    );
  }

  }
  if (errorMessage) {

  }
}

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 must display a button somewhere in your app in order to allow the user to restore its purchases.

await Iaphub.restore();

Present code redemption sheet (iOS only)

Call the presentCodeRedemptionSheet to display a sheet that enable users to redeem subscription offer codes that you configure in App Store Connect

await Iaphub.presentCodeRedemptionSheet();
