Python quickstart

Quickstarts explain how to set up and run an app that calls a Google Workspace API.

Google Workspace quickstarts use the API client libraries to handle some details of the authentication and authorization flow. We recommend that you use the client libraries for your own apps. Before you can run the sample app, each quickstart requires that you turn on authentication and authorization. If you're unfamiliar with authentication and authorization for Google Workspace APIs, read the Authentication and authorization overview.

Create a Python command-line application that makes requests to the Google Forms API.

Objectives

  • Set up your environment.
  • Install the client library.
  • Set up the sample.
  • Run the sample.

Prerequisites

To run this quickstart, you need the following prerequisites:

  • A Google Account.

Set up your environment

To complete this quickstart, set up your environment.

Enable the API

Before using Google APIs, you need to enable them in a Google Cloud project. You can enable one or more APIs in a single Google Cloud project.
  • In the Google Cloud console, enable the Google Forms API.

    Enable the API

Authorize credentials for a desktop application

To authenticate as an end user and access user data in your app, you need to create one or more OAuth 2.0 Client IDs. A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, you must create a separate client ID for each platform.
  1. In the Google Cloud console, go to the Credentials page.

    Go to Credentials

  2. Click Create Credentials > OAuth client ID.
  3. Click Application type > Desktop app.
  4. In the Name field, type a name for the credential. This name is only shown in the Google Cloud console.
  5. Click Create. The OAuth client created screen appears, showing your new Client ID and Client secret.
  6. Click OK. The newly created credential appears under OAuth 2.0 Client IDs.
Make a note of these credentials because you need them later in this quickstart.

Install the Google client library

  • Install the Google client library for Python:

    pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
    

Configure the sample

  1. In your working directory, create a file named quickstart.py.
  2. Include the following code in quickstart.py:

    forms/quickstart/quickstart.py
    from __future__ import print_function
    
    from apiclient import discovery
    from httplib2 import Http
    from oauth2client import client, file, tools
    
    SCOPES = "https://www.googleapis.com/auth/forms.body"
    DISCOVERY_DOC = "https://forms.googleapis.com/$discovery/rest?version=v1"
    
    store = file.Storage('token.json')
    creds = None
    if not creds or creds.invalid:
        flow = client.flow_from_clientsecrets('client_secrets.json', SCOPES)
        creds = tools.run_flow(flow, store)
    
    form_service = discovery.build('forms', 'v1', http=creds.authorize(
        Http()), discoveryServiceUrl=DISCOVERY_DOC, static_discovery=False)
    
    # Request body for creating a form
    NEW_FORM = {
        "info": {
            "title": "Quickstart form",
        }
    }
    
    # Request body to add a multiple-choice question
    NEW_QUESTION = {
        "requests": [{
            "createItem": {
                "item": {
                    "title": "In what year did the United States land a mission on the moon?",
                    "questionItem": {
                        "question": {
                            "required": True,
                            "choiceQuestion": {
                                "type": "RADIO",
                                "options": [
                                    {"value": "1965"},
                                    {"value": "1967"},
                                    {"value": "1969"},
                                    {"value": "1971"}
                                ],
                                "shuffle": True
                            }
                        }
                    },
                },
                "location": {
                    "index": 0
                }
            }
        }]
    }
    
    # Creates the initial form
    result = form_service.forms().create(body=NEW_FORM).execute()
    
    # Adds the question to the form
    question_setting = form_service.forms().batchUpdate(formId=result["formId"], body=NEW_QUESTION).execute()
    
    # Prints the result to show the question has been added
    get_result = form_service.forms().get(formId=result["formId"]).execute()
    print(get_result)
    

Run the sample

  1. In your working directory, build and run the sample:

    python quickstart.py
    
  2. The first time you run the sample, it prompts you to authorize access:

    1. If you're not already signed in to your Google Account, you're prompted to sign in. If you're signed in to multiple accounts, select one account to use for authorization.
    2. Click Accept.

    Authorization information is stored in the file system, so the next time you run the sample code, you aren't prompted for authorization.

You have successfully created your first Python application that makes requests to the Google Forms API.
