Obtaining an In-App Purchase key from App Store Connect

To use the App Store Server API or create promotional offer signatures, a signing key downloaded from App Store Connect is required. To obtain this key, you must have the Admin role. Go to Users and Access > Integrations > In-App Purchase. Here you can create and manage keys, as well as find your issuer ID. When using a key, you'll need the key ID and issuer ID as well.

Obtaining Apple Root Certificates

Download and store the root certificates found in the Apple Root Certificates section of the Apple PKI site. Provide these certificates as an array to a SignedDataVerifier to allow verifying the signed data comes from Apple.

Usage

API Usage

from appstoreserverlibrary.api_client import AppStoreServerAPIClient, APIException
from appstoreserverlibrary.models.Environment import Environment

private_key = read_private_key("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8") # Implementation will vary

key_id = "ABCDEFGHIJ"
issuer_id = "99b16628-15e4-4668-972b-eeff55eeff55"
bundle_id = "com.example"
environment = Environment.SANDBOX

client = AppStoreServerAPIClient(private_key, key_id, issuer_id, bundle_id, environment)

try:    
    response = client.request_test_notification()
    print(response)
except APIException as e:
    print(e)

Verification Usage

from appstoreserverlibrary.models.Environment import Environment
from appstoreserverlibrary.signed_data_verifier import VerificationException, SignedDataVerifier

root_certificates = load_root_certificates()
enable_online_checks = True
bundle_id = "com.example"
environment = Environment.SANDBOX
app_apple_id = None # appAppleId must be provided for the Production environment
signed_data_verifier = SignedDataVerifier(root_certificates, enable_online_checks, environment, bundle_id, app_apple_id)

try:    
    signed_notification = "ey.."
    payload = signed_data_verifier.verify_and_decode_notification(signed_notification)
    print(payload)
except VerificationException as e:
    print(e)

Receipt Usage

from appstoreserverlibrary.api_client import AppStoreServerAPIClient, APIException, GetTransactionHistoryVersion
from appstoreserverlibrary.models.Environment import Environment
from appstoreserverlibrary.receipt_utility import ReceiptUtility
from appstoreserverlibrary.models.HistoryResponse import HistoryResponse
from appstoreserverlibrary.models.TransactionHistoryRequest import TransactionHistoryRequest, ProductType, Order

private_key = read_private_key("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8") # Implementation will vary

key_id = "ABCDEFGHIJ"
issuer_id = "99b16628-15e4-4668-972b-eeff55eeff55"
bundle_id = "com.example"
environment = Environment.SANDBOX

client = AppStoreServerAPIClient(private_key, key_id, issuer_id, bundle_id, environment)
receipt_util = ReceiptUtility()
app_receipt = "MI.."

try:    
    transaction_id = receipt_util.extract_transaction_id_from_app_receipt(app_receipt)
    if transaction_id != None:
        transactions = []
        response: HistoryResponse = None
        request: TransactionHistoryRequest = TransactionHistoryRequest(
            sort=Order.ASCENDING,
            revoked=False,
            productTypes=[ProductType.AUTO_RENEWABLE]
        )
        while response == None or response.hasMore:
            revision = response.revision if response != None else None
            response = client.get_transaction_history(transaction_id, revision, request, GetTransactionHistoryVersion.V2)
            for transaction in response.signedTransactions:
                transactions.append(transaction)
        print(transactions)
except APIException as e:
    print(e)

Promotional Offer Signature Creation

from appstoreserverlibrary.promotional_offer import PromotionalOfferSignatureCreator
import time

private_key = read_private_key("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8") # Implementation will vary

key_id = "ABCDEFGHIJ"
bundle_id = "com.example"

promotion_code_signature_generator = PromotionalOfferSignatureCreator(private_key, key_id, bundle_id)

product_id = "<product_id>"
subscription_offer_id = "<subscription_offer_id>"
application_username = "<application_username>"
nonce = "<nonce>"
timestamp = round(time.time()*1000)
base64_encoded_signature = promotion_code_signature_generator.create_signature(product_id, subscription_offer_id, application_username, nonce, timestamp)

Async HTTPX Support

Pip

Include the optional async dependency

pip install app-store-server-library[async]

API Usage

from appstoreserverlibrary.api_client import AsyncAppStoreServerAPIClient, APIException
from appstoreserverlibrary.models.Environment import Environment

private_key = read_private_key("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8") # Implementation will vary

key_id = "ABCDEFGHIJ"
issuer_id = "99b16628-15e4-4668-972b-eeff55eeff55"
bundle_id = "com.example"
environment = Environment.SANDBOX

client = AsyncAppStoreServerAPIClient(private_key, key_id, issuer_id, bundle_id, environment)

try:    
    response = await client.request_test_notification()
    print(response)
except APIException as e:
    print(e)

# Once client use is finished
await client.async_close()

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.
