Google Calendar is a time-management and scheduling calendar service developed by Google.
This component allows you to create, read, update and delete events and calendars connected to your Google account.

Connections

OAuth 2.0

OAuth 2.0 connection for Google Calendar

The Google Calendar component authenticates requests through the Google Cloud Platform (GCP) OAuth 2.0 service.
A GCP OAuth 2.0 app is required for the integration to authenticate and perform Google Calendar tasks on behalf of users.

Prerequisites

Setup Steps

To create a Google Calendar OAuth 2.0 app:

  1. Open the Google Calendar API console at https://console.cloud.google.com/apis/api/calendar-json.googleapis.com
  2. Click CREATE PROJECT to create a new GCP project, or select an existing project.
  3. Enable the Google Calendar API for the project by clicking ENABLE.
  4. On the sidebar, select Credentials.
  5. Configure the OAuth 2.0 Consent Screen (the page that asks "Do you want to allow (Your Company) to access Google Calendar on your behalf?"). Click CONFIGURE CONSENT SCREEN.
    1. Choose a User Type of External so the app will be available to customers.
    2. Fill out the OAuth consent screen with an app name (company or product name), support email, app logo, domain, etc.
    3. Domains can be ignored for now.
    4. On the next page, add the scope https://www.googleapis.com/auth/calendar.
    5. Enter some test users for testing purposes.
      The app will only work for those testing users until it is "verified" by Google.
      When ready for verification (Google verifies privacy policy statement, etc), click PUBLISH APP on the OAuth consent screen.
      This will allow customers to authorize the integration to access their Google Calendar.
  6. Once the "Consent Screen" is configured, open the Credentials page from the sidebar again.
  7. Click +CREATE CREDENTIALS and select OAuth client ID.
    1. Under Application type select Web application.
    2. Under Authorized redirect URIs enter the OAuth 2.0 callback URL: https://oauth2.flowbuilder.eu.lansweeper.com/callback for EU sites or https://oauth2.flowbuilder.us.lansweeper.com/callback for US sites
    3. Click CREATE.
  8. Copy the Client ID and Client Secret that are generated.

App Verification

Google requires OAuth apps that request access to user data to pass a verification review before being deployed at scale. This process ensures the app complies with Google's API Services User Data Policy, accurately represents its functionality, and handles user data responsibly.

Google OAuth apps pass through three stages before they are ready for production use.

Testing (unpublished): The app is only accessible to users manually added as test users in the OAuth consent screen. Up to 100 test users are allowed — all other users receive an error. This is the expected state during initial development.

Published, unverified: After publishing the app, all Google users can authenticate. However, for sensitive scopes, users see a "This app isn't verified" warning. Users can proceed by clicking Advanced → Go to [app name] (unsafe), but this warning reduces trust and may be blocked by organizations with strict Google Workspace policies.

Verified: Google has reviewed and approved the app. No warning is shown. Verification is required before deploying to production users.

Publishing the App

Publishing is required before any users outside the test list can authenticate:

  1. In the Google Cloud Console, navigate to APIs & Services → OAuth consent screen
  2. Click PUBLISH APP and confirm

Requesting Verification

The scopes used by this component are classified as sensitive by Google. Submitting for verification removes the "This app isn't verified" warning:

  1. On the OAuth consent screen, click Prepare for verification
  2. Provide a privacy policy URL, authorized domain, and app logo
  3. Submit for review — Google typically responds within several weeks

Refer to Google's OAuth consent screen documentation for the full verification requirements.

This connection uses OAuth 2.0, a common authentication mechanism for integrations.
