# In-App Purchase (macOS)
|
||
|
||
## Preparing
|
||
|
||
### Paid Applications Agreement
|
||
If you haven't already, you’ll need to sign the Paid Applications Agreement and set up your banking and tax information in iTunes Connect.
|
||
|
||
[iTunes Connect Developer Help: Agreements, tax, and banking overview](https://help.apple.com/itunes-connect/developer/#/devb6df5ee51)
|
||
|
||
### Create Your In-App Purchases
|
||
Then, you'll need to configure your in-app purchases in iTunes Connect, and include details such as name, pricing, and description that highlights the features and functionality of your in-app purchase.

||

|
||
|
||
### Change the CFBundleIdentifier
|
||
|
||
To test In-App Purchase in development with Electron you'll have to change the `CFBundleIdentifier` in `node_modules/electron/dist/Electron.app/Contents/Info.plist`. You have to replace `com.github.electron` by the bundle identifier of the application you created with iTunes Connect.
|
||
|
||
```xml
|
||
<key>CFBundleIdentifier</key>
|
||
<string>com.example.app</string>
|
||
```
|
||
|
||
## 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.
|
||
|
||
```javascript
|
||
const { inAppPurchase } = require('electron').remote
|
||
const PRODUCT_IDS = ['id1', 'id2']
|
||
|
||
// Listen for transactions as soon as possible.
|
||
inAppPurchase.on('transactions-updated', (event, transactions) => {
|
||
if (!Array.isArray(transactions)) {
|
||
return
|
||
}
|
||
|
||
// Check each transaction.
|
||
transactions.forEach(function (transaction) {
|
||
const payment = transaction.payment
|
||
|
||
switch (transaction.transactionState) {
|
||
case 'purchasing':
|
||
console.log(`Purchasing ${payment.productIdentifier}...`)
|
||
break
|
||
|
||
case 'purchased': {
|
||
console.log(`${payment.productIdentifier} purchased.`)
|
||
|
||
// Get the receipt url.
|
||
const receiptURL = inAppPurchase.getReceiptURL()
|
||
|
||
console.log(`Receipt URL: ${receiptURL}`)
|
||
|
||
// Submit the receipt file to the server and check if it is valid.
|
||
// @see https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
|
||
// ...
|
||
// If the receipt is valid, the product is purchased
|
||
// ...
|
||
|
||
// Finish the transaction.
|
||
inAppPurchase.finishTransactionByDate(transaction.transactionDate)
|
||
|
||
break
|
||
}
|
||
|
||
case 'failed':
|
||
|
||
console.log(`Failed to purchase ${payment.productIdentifier}.`)
|
||
|
||
// Finish the transaction.
|
||
inAppPurchase.finishTransactionByDate(transaction.transactionDate)
|
||
|
||
break
|
||
case 'restored':
|
||
|
||
console.log(`The purchase of ${payment.productIdentifier} has been restored.`)
|
||
|
||
break
|
||
case 'deferred':
|
||
|
||
console.log(`The purchase of ${payment.productIdentifier} has been deferred.`)
|
||
|
||
break
|
||
default:
|
||
break
|
||
}
|
||
})
|
||
})
|
||
|
||
// Check if the user is allowed to make in-app purchase.
|
||
if (!inAppPurchase.canMakePayments()) {
|
||
console.log('The user is not allowed to make in-app purchase.')
|
||
}
|
||
|
||
// Retrieve and display the product descriptions.
|
||
inAppPurchase.getProducts(PRODUCT_IDS).then(products => {
|
||
// Check the parameters.
|
||
if (!Array.isArray(products) || products.length <= 0) {
|
||
console.log('Unable to retrieve the product informations.')
|
||
return
|
||
}
|
||
|
||
// Display the name and price of each product.
|
||
products.forEach(product => {
|
||
console.log(`The price of ${product.localizedTitle} is ${product.formattedPrice}.`)
|
||
})
|
||
|
||
// Ask the user which product he/she wants to purchase.
|
||
const selectedProduct = products[0]
|
||
const selectedQuantity = 1
|
||
|
||
// Purchase the selected product.
|
||
inAppPurchase.purchaseProduct(selectedProduct.productIdentifier, selectedQuantity).then(isProductValid => {
|
||
if (!isProductValid) {
|
||
console.log('The product is not valid.')
|
||
return
|
||
}
|
||
|
||
console.log('The payment has been added to the payment queue.')
|
||
})
|
||
})
|
||
```
