Usage

API Usage

import { AppStoreServerAPIClient, Environment, SendTestNotificationResponse } from "@apple/app-store-server-library"

const issuerId = "99b16628-15e4-4668-972b-eeff55eeff55"
const keyId = "ABCDEFGHIJ"
const bundleId = "com.example"
const filePath = "/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8"
const encodedKey = readFile(filePath) // Specific implementation may vary
const environment = Environment.SANDBOX

const client = new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment)

try {
    const response: SendTestNotificationResponse = await client.requestTestNotification()
    console.log(response)
} catch (e) {
    console.error(e)
}

Verification Usage

import { SignedDataVerifier } from "@apple/app-store-server-library/dist/jwt_verification"

const bundleId = "com.example"
const appleRootCAs: Buffer[] = loadRootCAs() // Specific implementation may vary
const enableOnlineChecks = true
const environment = Environment.SANDBOX
const verifier = new SignedDataVerifier(appleRootCAs, enableOnlineChecks, environment, bundleId)

const notificationPayload = "ey..."
const verifiedNotification = await verifier.verifyAndDecodeNotification()
console.log(verifiedNotification)

Receipt Usage

import { AppStoreServerAPIClient, Environment, ReceiptUtility, Order, ProductType, HistoryResponse, TransactionHistoryRequest } from "@apple/app-store-server-library"

const issuerId = "99b16628-15e4-4668-972b-eeff55eeff55"
const keyId = "ABCDEFGHIJ"
const bundleId = "com.example"
const filePath = "/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8"
const encodedKey = readFile(filePath) // Specific implementation may vary
const environment = Environment.SANDBOX

const client =
        new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment)

const appReceipt = "MI..."
const receiptUtil = new ReceiptUtility()
const transactionId = receiptUtil.extractTransactionIdFromAppReceipt(appReceipt)
if (transactionId != null) {
    const transactionHistoryRequest: TransactionHistoryRequest = {
        sort: Order.ASCENDING,
        revoked: false,
        productTypes: [ProductType.AUTO_RENEWABLE]
    }
    let response: HistoryResponse | null = null
    let transactions: string[] = []
    do {
        const revisionToken = response !== null && response.revision !== null ? response.revision : null
        response = await client.getTransactionHistory(transactionId, revisionToken, transactionHistoryRequest)
        if (response.signedTransactions) {
            transactions = transactions.concat(response.signedTransactions)
        }
    } while (response.hasMore)
    console.log(transactions)
}

Promotional Offer Signature Creation

import { PromotionalOfferSignatureCreator } from "@apple/app-store-server-library"

const keyId = "ABCDEFGHIJ"
const bundleId = "com.example"
const filePath = "/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8"
const encodedKey = readFile(filePath) // Specific implementation may vary

const productId = "<product_id>"
const subscriptionOfferId = "<subscription_offer_id>"
const applicationUsername = "<application_username>"
const signatureCreator = new PromotionalOfferSignatureCreator(encodedKey, keyId, bundleId)

const signature = signatureCreator.createSignature(productId, subscriptionOfferId, signatureCreator)
console.log(signature)

Support

Only the latest major version of the library will receive updates, including security updates. Therefore, it is recommended to update to new major versions.
