InAppPy

In-app purchase validation library for Apple AppStore and GooglePlay.

Installation

pip install inapppy

Usage

Currently inapppy supports Google Play and App Store receipts validation.

Google Play (validates receipt against provided signature using RSA):

from inapppy import GooglePlayValidator, InAppPyValidationError


bundle_id = 'com.yourcompany.yourapp'
api_key = 'API key from the developer console'
validator = GooglePlayValidator(bundle_id, api_key)

try:
    validation_result = validator.validate('receipt', 'signature')
except InAppPyValidationError:
    # handle validation error
    pass

Google Play verification:

from inapppy import GooglePlayVerifier, errors


def google_validator(in_receipt):
    """
    Accepts receipt, validates in Google.
    """
    purchase_token = receipt['purchaseToken']
    product_sku = receipt['productId']
    verifier = GooglePlayValidator(
        GOOGLE_BUNDLE_ID,
        GOOGLE_SERVICE_ACCOUNT_KEY_FILE,
    )
    response = {'valid': False, 'transactions': []}
    try:
        result = verifier.verify(
            purchase_token,
            product_sku
        )
        response['valid'] = True
        response['transactions'].append(
            (result['orderId'], product_sku)
        )
    except errors.GoogleError as exc:
        logging.error('Purchase validation failed {}'.format(exc))
    return response

App Store (validates receipt using optional shared-secret against iTunes service):

from inapppy import AppStoreValidator, InAppPyValidationError


bundle_id = 'com.yourcompany.yourapp'
auto_retry_wrong_env_request=False # if True, automatically query sandbox endpoint if
                                   # validation fails on production endpoint
validator = AppStoreValidator(bundle_id, auto_retry_wrong_env_request=auto_retry_wrong_env_request)

try:
    exclude_old_transactions=False # if True, include only the latest renewal transaction
    validation_result = validator.validate('receipt', 'optional-shared-secret', exclude_old_transactions=exclude_old_transactions)
except InAppPyValidationError as ex:
    # handle validation error
    response_from_apple = ex.raw_response  # contains actual response from AppStore service.
    pass
