Google Drive authentication

Prerequisites

Depending on the authentication type you select, you need one of the following credentials:

• OAuth 2.0 Authorization code: Your Google email address and the password associated with your Google account.
• Bring your own OAuth 2.0 app: Your application's Client ID and Client secret, and Scopes.
• Service account: Service account key, Account email.

Once authenticated, you can use the connection to access the different functionalities offered by the Google Drive.

If your account is not enabled by Google:

• Reach out to your administrator for approvals on creating connections.
• Enable permission by checking the options available to allow creating a connection.

For more information on Google Drive, refer to Google Drive developer documentation.

Scopes

The connector requests the following permissions/scopes:

• UiPath public app default scopes: openid, https://www.googleapis.com/auth/userinfo.email, https://www.googleapis.com/auth/userinfo.profile, https://www.googleapis.com/auth/drive.
• Service account default scopes: openid, https://www.googleapis.com/auth/userinfo.email, https://www.googleapis.com/auth/userinfo.profile, https://www.googleapis.com/auth/drive.
• Bring your own OAuth 2.0 app:
  • Minimal scopes for creating a connection: openid, https://www.googleapis.com/auth/drive.readonly.
  • Minimal list of scopes required for Google Drive triggers:
    • openid, https://www.googleapis.com/auth/drive.readonly

Note: If you authenticate using Bring your own OAuth 2.0 app, you benefit by default from the scopes configured at app creation. If you want to use the default app permissions, you can declare a common scope. This means you use only the permissions configured for that application. You can also declare additional scopes at connection creation, using the Scopes field. You will then be asked to grant the additional consent during sign-in.

Connecting allows UiPath products to interact with Google Drive data on your behalf. This may include read, write, modify and delete data, depending on your Google Drive permissions. You can always remove any access in your Google Account.

Add the Google Drive connection

1. Select Integration Service from Automation Cloud^TM.

2. From the Connectors list, select Google Drive. You can also use the search bar to find the connector.

3. You are now redirected to the connection page. Select your preferred authentication type, add the required credentials, and select Connect.

   If you select Bring your own OAuth 2.0 app, you must provide a Client ID and Client secret, and the Scopes you may need to interact with different activities. Check out the activities' documentation to see what scopes they require.

4. Your connection has been added.

Refresh tokens for OAuth applications

Google has refresh token limitations for individual OAuth 2.0 client IDs. If the limit is reached, creating a new refresh token automatically invalidates the oldest refresh token without warning. This limit does not apply to service accounts (see Using OAuth 2.0 for Server-to-Server Applications). For more information, see Google's official documentation.

A list of reasons which can cause token expiry:

• You have revoked your app's access.
• The refresh token has not been used for six months.
• You need to change passwords and the refresh token contains Gmail scopes.
• Your account has exceeded a maximum number of granted (live) refresh tokens.
  • If you request a new token after the limit is exceeded, your old connection, based on a previously granted token, will expire. Only the new connection or the latest edited/reauthenticated connection (with the latest token) will work.
• An admin has set any of the services requested in your application's scopes to Restricted (the error is admin_policy_enforced).
• For Google Cloud Platform APIs: the session length set by the admin could have been exceeded.

Note: The limit is currently set to 100 refresh tokens per Google account per OAuth 2.0 client ID. This number can be subject to change. For the latest information, always check the Google documentation.

There is a larger limit on the total number of refresh tokens a user account or service account can have across all clients. Regular users won't exceed this limit, but a developer account used to test an implementation might.

To make sure this limit is not exceeded, UiPath offers users the ability to create their own OAuth applications and connect using the Bring your own app authentication type. Make sure to follow the best practices from Google when creating your OAuth application. For details on how to create an OAuth application, see Google's official documentation.

Warning: Token invalidation results in failed connections and automations are unable to run without fixing connections.
