Google App for Streams

In this guide, you'll setup a Google app, create your Integration, and Grant an account access to your Integration.

Before you create your application with Google there are a few things to keep in mind.

Internal or External Application

Decide if you want your application available to anyone or only users part of your organization.

Internal Application

Use internal users for Google account access for development or production applications that are internal only. Only users who have an account within your organization, @your-organization.com, can access the application.

When users from your organization authorize against your application they will not see the unverified application warning.

Use internal applications to skip the App Verification and Security Review process. If anyone outside your organization needs to verify against your application at any time, you will need to go through the Google security review.

External Application

Use external users if you are creating a production app and will need to go through Google security verification. This option will allow users who are not in your organization to authenticate against your application.

When users from your organization authorize against your application they will see the unverified application warning.

External apps are limited to 100 accounts before verification.

Configure your OAuth screen

You can configure your application's OAuth screen. This is the page users will see when they authenticate your application.

  1. From the Google APIs dashboard, click OAuth consent screen.
  2. Choose your user type, either Internal or External.

  2. Save and Continue.
  3. Click Add or Remove Scopes. Select
    1. .../auth/userinfo.email
    2. .../auth/userinfo.profile
    3. openid

  5. Review the Summary and make sure the information is correct for your application.
  6. Click Back to Dashboard.
  7. Under the heading Publishing status, click Publish App. Publishing your app makes it so that you authorize users using the Nylas API instead of needing to add them one at a time to the Google test users. The app will show as unverified until you go through the Google Security Review.

  7. You’ll see your client ID and secret displayed in OAuth client created. Save this someplace safe. You’ll need these for your Nylas application.

Create a Google Integration

💡 Tip: You can skip this step if you've already created an integration.

Before you begin, make sure you've added the redirect URI to your new application:

  • U.S. region: https://datastreams.us.nylas.com/v3/connect/callback

After you set your redirect URI, you can create your integration:

  1. Go to the Nylas Dashboard and select Integration.
  2. Choose the integration you want to create.
  3. Enter your client ID, client secret, and redirect URI.
