The provided references do not contain information regarding the steps to create a Google Sheets OAuth2 single service. However, generally, the following steps can be followed to set up a Google Sheets OAuth2 service: ### Enable the Google Sheets API 1. Go to the [Google API Console](https://console.developers.google.com/). 2. Create a new project or select an existing one. 3. In the left - hand sidebar, click on "Library". 4. Search for "Google Sheets API" and enable it for your project. ### Configure the OAuth consent screen 1. In the API Console, click on "OAuth consent screen" in the left - hand sidebar. 2. Select the user type (External or Internal depending on your use case). 3. Fill in the required information such as app name, user support email, and developer contact information. 4. Add the scopes you need. For Google Sheets, you'll likely need at least `https://www.googleapis.com/auth/spreadsheets.readonly` or `https://www.googleapis.com/auth/spreadsheets` depending on whether you only need read - only access or full access. 5. Add test users if you're in testing mode. 6. Save your changes. ### Create OAuth2 credentials 1. Click on "Credentials" in the left - hand sidebar. 2. Click the "+ Create credentials" button and select "OAuth client ID". 3. Select the application type (e.g., Web application, Desktop app, etc.). 4. For a web application, enter the authorized JavaScript origins and redirect URIs. For example, if you're using a local development server, the redirect URI might be `http://localhost:8080/oauth2callback`. 5. Click "Create". 6. You'll be presented with a client ID and client secret. Save these securely as you'll need them in your application code. ### Use the credentials in your application The following is a simple Python example using the `google - api - python - client` library to access Google Sheets with OAuth2: ```python from google.oauth2.credentials import Credentials from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow # Replace with the path to the JSON file containing your client ID and secret CLIENT_SECRETS_FILE = 'client_secret.json' SCOPES = ['https://www.googleapis.com/auth/spreadsheets.readonly'] flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES) credentials = flow.run_local_server(port=0) service = build('sheets', 'v4', credentials=credentials) # Replace with the ID of your Google Sheet spreadsheet_id = 'your_spreadsheet_id' range_name = 'Sheet1!A1:B2' result = service.spreadsheets().values().get(spreadsheetId=spreadsheet_id, range=range_name).execute() values = result.get('values', []) if not values: print('No data found.') else: for row in values: print(row) ```
