+# This application demonstrates the usage of the Analytics Admin API using
+# service account credentials. For more information on service accounts, see
+#
+# https://cloud.google.com/iam/docs/understanding-service-accounts
+#
+# The following document provides instructions on setting service account
+# credentials for your application:
+#
+#   https://cloud.google.com/docs/authentication/production
+#
+# In a nutshell, you need to:
+# 1. Create a service account and download the key JSON file.
+#
+# https://cloud.google.com/docs/authentication/production#creating_a_service_account
+#
+# 2. Provide service account credentials using one of the following options:
+# - set the GOOGLE_APPLICATION_CREDENTIALS environment variable, the API
+# client will use the value of this variable to find the service account key
+# JSON file.
+#
+# https://cloud.google.com/docs/authentication/production#setting_the_environment_variable
+#
+# OR
+# - manually pass the path to the service account key JSON file to the API client
+# by specifying the keyFilename parameter in the constructor:
+# https://cloud.google.com/docs/authentication/production#passing_the_path_to_the_service_account_key_in_code
+
+# To install the latest published package dependency, execute the following:
+#   pip install google-analytics-admin
+from google.analytics.admin import AnalyticsAdminServiceClient
+
+
+def main():
+  # Using a default constructor instructs the client to use the credentials
+  # specified in GOOGLE_APPLICATION_CREDENTIALS environment variable.
+  client = AnalyticsAdminServiceClient()
+
+  # Displays the configuration information for all Google Analytics accounts
+  # available to the authenticated user.
+  for account in client.list_accounts():
+    print(account)
