Complete the steps described in the rest of this page to create a simple Python command-line application that makes requests to the Google Calendar API.
To run this quickstart, you'll need:
- Python 2.6 or greater
- The pip package management tool
- A Google account with Google Calendar enabled
Step 1: Turn on the Google Calendar API
Click this button to create a new console project and automatically enable the Google Calendar API:
This opens a new dialog. In the dialog, do the following:
- Select + Create a new project.
- Download the configuration file.
- Move the downloaded file to your working directory and ensure it is named
Step 2: Install the Google Client Library
Run the following command to install the library using pip:
pip install --upgrade google-api-python-client oauth2client
See the library's installation page for the alternative installation options.
Step 3: Set up the sample
Create a file named
quickstart.py in your working directory and copy in the
from __future__ import print_function import datetime from googleapiclient.discovery import build from httplib2 import Http from oauth2client import file, client, tools # If modifying these scopes, delete the file token.json. SCOPES = 'https://www.googleapis.com/auth/calendar.readonly' def main(): """Shows basic usage of the Google Calendar API. Prints the start and name of the next 10 events on the user's calendar. """ # The file token.json stores the user's access and refresh tokens, and is # created automatically when the authorization flow completes for the first # time. store = file.Storage('token.json') creds = store.get() if not creds or creds.invalid: flow = client.flow_from_clientsecrets('credentials.json', SCOPES) creds = tools.run_flow(flow, store) service = build('calendar', 'v3', http=creds.authorize(Http())) # Call the Calendar API now = datetime.datetime.utcnow().isoformat() + 'Z' # 'Z' indicates UTC time print('Getting the upcoming 10 events') events_result = service.events().list(calendarId='primary', timeMin=now, maxResults=10, singleEvents=True, orderBy='startTime').execute() events = events_result.get('items', ) if not events: print('No upcoming events found.') for event in events: start = event['start'].get('dateTime', event['start'].get('date')) print(start, event['summary']) if __name__ == '__main__': main()
Step 4: Run the sample
Run the sample using the following command:
The sample will attempt to open a new window or tab in your default browser. If this fails, copy the URL from the console and manually open it in your browser.
If you are not already logged into your Google account, you will be prompted to log in. If you are logged into multiple Google accounts, you will be asked to select one account to use for the authorization.
- Click the Accept button.
- The sample will proceed automatically, and you may close the window/tab.
- Authorization information is stored on the file system, so subsequent executions will not prompt for authorization.
- The authorization flow in this example is designed for a command-line application. For information on how to perform authorization in a web application, see Using OAuth 2.0 for Web Server Applications.

AttributeError: 'Module_six_moves_urllib_parse' object has no attribute 'urlparse'
This error can occur in Mac OSX where the default installation of the
module (a dependency of this library) is loaded before the one that pip
installed. To fix the issue, add pip's install location to the
system environment variable:
Determine pip's install location with the following command:
pip show six | grep "Location:" | cut -d " " -f2
Add the following line to your
<pip_install_path>with the value determined above:
~/.bashrcfile in any open terminal windows using the following command:
TypeError: sequence item 0: expected str instance, bytes found
This error is due to a bug in
httplib2, and upgrading to the latest version
should resolve it:
pip install --upgrade httplib2
