You can turn on one or more APIs in a single Google Cloud project.\n\n- In the Google Cloud console, enable the Google Apps Script API.\n\n [Enable the API](https://console.cloud.google.com/apis/enableflow?apiid=script.googleapis.com)\n\nConfigure the OAuth consent screen\n\nIf you're using a new Google Cloud project to complete this quickstart, configure\nthe OAuth consent screen. If you've already\ncompleted this step for your Cloud project, skip to the next section.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Branding** .\n\n [Go to Branding](https://console.cloud.google.com/auth/branding)\n2. If you have already configured the Google Auth platform, you can configure the following OAuth Consent Screen settings in [Branding](https://console.cloud.google.com/auth/branding), [Audience](https://console.cloud.google.com/auth/audience), and [Data Access](https://console.cloud.google.com/auth/scopes). If you see a message that says **Google Auth platform not configured yet** , click **Get Started**:\n 1. Under **App Information** , in **App name**, enter a name for the app.\n 2. In **User support email**, choose a support email address where users can contact you if they have questions about their consent.\n 3. Click **Next**.\n 4. Under **Audience** , select **Internal**.\n 5. Click **Next**.\n 6. Under **Contact Information** , enter an **Email address** where you can be notified about any changes to your project.\n 7. Click **Next**.\n 8. Under **Finish** , review the [Google API Services User Data Policy](https://developers.google.com/terms/api-services-user-data-policy) and if you agree, select **I agree to the Google API Services: User Data Policy**.\n 9. Click **Continue**.\n 10. Click **Create**.\n3. For now, you can skip adding scopes. In the future, when you create an app for use outside of your Google Workspace organization, you must change the **User type** to **External** . Then add the authorization scopes that your app requires. To learn more, see the full [Configure OAuth consent](/workspace/guides/configure-oauth-consent) guide.\n\nAuthorize credentials for a desktop application To authenticate end users 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.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Clients** .\n\n [Go to Clients](https://console.cloud.google.com/auth/clients)\n2. Click **Create Client**.\n3. Click **Application type** \\\u003e **Desktop app**.\n4. In the **Name** field, type a name for the credential. This name is only shown in the Google Cloud console.\n5. Click **Create** .\n\n\n The newly created credential appears under \"OAuth 2.0 Client IDs.\"\n6. Save the downloaded JSON file as `credentials.json`, and move the file to your working directory.\n\nPrepare the workspace\n\n1. Create a working directory:\n\n ```\n mkdir quickstart\n ```\n2. Change to the working directory:\n\n ```\n cd quickstart\n ```\n3. Initialize the new module:\n\n ```\n go mod init quickstart\n ```\n4.
