# Set up Gmail with Nango

> Register an OAuth app with Gmail and connect it to Nango

This guide shows you how to register your own app with Google to obtain your OAuth credentials (client ID & secret). These are required to let your users grant your app access to their Gmail account.

<Info>
  You will need to pass a security review to go live with your integration.

  [Follow our guide](/api-integrations/google-shared/google-security-review) to get approved as fast as possible.

## Create your OAuth App

<Steps>
  <Step title="Create a Google Cloud account">
    If you don't already have one, sign up for a [Google Cloud account](https://console.cloud.google.com/).
  </Step>

  <Step title="Create a new project">
    1. Go to the [Google Cloud Console](https://console.cloud.google.com/).
    2. Click on the project dropdown at the top left of the page.
    3. Click **New Project**.
    4. Enter a **Project Name** for your project.
    5. Under **Location**, select the appropriate organization or folder where this project should belong.
       <Note>If you're not part of an organization, it will default to No organization</Note>
    6. Click **Create** and wait for the project to be created.
    7. Select it from the project dropdown.
  </Step>

  <Step title="Enable the APIs you need">
    1. Go to the [API Library](https://console.cloud.google.com/apis/library) in the Google Cloud Console.
    2. Search for **Gmail API** and select it, then click **Enable**.
  </Step>

  <Step title="Configure the OAuth consent screen">
    1. Go to **APIs & Services** > **OAuth consent screen** in the Google Cloud Console.
    2. Click **Get started**.
    3. Fill in the **App Information** form.

    * **App Name**: The name of the app asking for consent.
    * **User support email**: For users to contact you with questions about their consent.

    4. Click **Next**. Select the appropriate Audience:
       * **External**: For applications available to any Google user
       * **Internal**: For applications restricted to users within your Google Workspace organization
    5. Click **Next**. Fill in the **Contact Information**; these are the email addresses that Google will use to notify you about any changes to your project.
    6. Click **Next**, then check the **I agree to the Google API Services: User Data Policy** checkbox, and click **Continue**.
    7. Add the scopes your application needs. Under **Data Access**, click **Add or Remove Scopes** and select the scopes that correspond to the APIs you enabled.
    8. Under **Audience**, click **Add users** if you selected **External** user type (required for testing before verification).
  </Step>

  <Step title="Create OAuth 2.0 credentials">
    1. Go to **APIs & Services** > **Credentials** in the Google Cloud Console.
    2. Click **Create Credentials** and select **OAuth client ID**.
    3. Select **Web application** as the application type.
    4. Enter a name for your OAuth client.
    5. Under **Authorized redirect URIs**, add `https://api.nango.dev/oauth/callback`.
    6. Click **Create**.
    7. A dialog will appear with your client ID and client secret. Save these credentials securely as you'll need them when configuring your integration in Nango.
  </Step>

  <Step title="Start building your integration">
    Follow the [*Quickstart*](/getting-started/quickstart) to build your integration.
  </Step>

  <Step title="Verify your app">
    Most Gmail scopes are marked "sensitive" or "restricted" by Google. You can develop in test mode, but you need to pass a security review to go live.

    [Follow our guide](/api-integrations/google-shared/google-security-review) to prepare and pass as quickly as possible.
  </Step>

  <Step title="Publish your app (switch from Testing to Production)">
    To move your OAuth app from testing to production:

    1. Go to **APIs & Services** > **OAuth consent screen** > **Audience**.
    2. Click **Publish App** to switch your app from testing to production.
  </Step>
</Steps>
