    iTunes Connect Developer Help: Create an in-app purchase

    Code example

    Here is an example that shows how to use In-App Purchases in Electron. You’ll have to replace the product ids by the identifiers of the products created with iTunes Connect (the identifier of com.example.app.product1 is product1). Note that you have to listen to the transactions-updated event as soon as possible in your app.

    1. // Main process
    2. const { inAppPurchase } = require('electron')
    3. const PRODUCT_IDS = ['id1', 'id2']
    5. // Listen for transactions as soon as possible.
    6. inAppPurchase.on('transactions-updated', (event, transactions) => {
    7.   if (!Array.isArray(transactions)) {
    8.     return
    9.   }
    11.   // Check each transaction.
    12.   transactions.forEach((transaction) => {
    13.     const payment = transaction.payment
    15.     switch (transaction.transactionState) {
    16.       case 'purchasing':
    17.         console.log(`Purchasing ${payment.productIdentifier}...`)
    18.         break
    20.       case 'purchased': {
    21.         console.log(`${payment.productIdentifier} purchased.`)
    23.         // Get the receipt url.
    24.         const receiptURL = inAppPurchase.getReceiptURL()
    26.         console.log(`Receipt URL: ${receiptURL}`)
    28.         // @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
    29.         // ...
    30.         // If the receipt is valid, the product is purchased
    31.         // ...
    33.         // Finish the transaction.
    34.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    36.         break
    37.       }
    39.       case 'failed':
    41.         console.log(`Failed to purchase ${payment.productIdentifier}.`)
    43.         // Finish the transaction.
    44.         inAppPurchase.finishTransactionByDate(transaction.transactionDate)
    46.         break
    47.       case 'restored':
    49.         console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
    51.         break
    52.       case 'deferred':
    54.         console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
    56.         break
    57.       default:
    58.         break
    59.     }
    60. })
    62. // Check if the user is allowed to make in-app purchase.
    63. if (!inAppPurchase.canMakePayments()) {
    64.   console.log('The user is not allowed to make in-app purchase.')
    65. }
    67. // Retrieve and display the product descriptions.
    68. inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
    69.   // Check the parameters.
    70.   if (!Array.isArray(products) || products.length <= 0) {
    71.     console.log('Unable to retrieve the product informations.')
    72.     return
    73.   }
    75.   // Display the name and price of each product.
    76.   products.forEach(product => {
    77.     console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
    78.   })
    80.   // Ask the user which product they want to purchase.
    81.   const selectedProduct = products[0]
    82.   const selectedQuantity = 1
    84.   // Purchase the selected product.
    85.   inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
    86.     if (!isProductValid) {
    87.       console.log('The product is not valid.')
    88.       return
    89.     }
    91.     console.log('The payment has been added to the payment queue.')
    92. })
