Usage

API Usage

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

private_key = read_private_key("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8") # Implemenation 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
signed_data_verifier = SignedDataVerifier(root_certificates, enable_online_checks, environment, bundle_id)

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

Receipt Usage

from appstoreserverlibrary.api_client import AppStoreServerAPIClient, APIException
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") # Implemenation 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)
            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") # Implemenation 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)

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.
