# Google Drive Connector

Connect your Google Drive account to upload and process files directly as an external knowledge base. Supports Google Workspace files (Docs, Sheets, Slides), Office files, PDFs, text files, CSVs, images, and more. Authentication is handled via Google OAuth 2.0 with automatic token refresh.

## Setup

<Steps>

### Step 1: Create a Google Cloud Project

1. Go to the [Google Cloud Console](https://console.cloud.google.com/) and create a new project (or select an existing one)
2. Navigate to **APIs & Services** > **Library**, search for "Google Drive API", and click **Enable**

### Step 2: Create OAuth 2.0 Credentials

1. Go to **APIs & Services** > **Credentials** > **Create Credentials** > **OAuth client ID**
2. If prompted, configure the OAuth consent screen (choose **External**, fill in required fields)
3. Select **Web application** as the application type
4. Add your DocsGPT URL to **Authorized JavaScript origins** (e.g. `http://localhost:3000`)
5. Add your callback URL to **Authorized redirect URIs**:
   - Local: `http://localhost:7091/api/connectors/callback?provider=google_drive`
   - Production: `https://yourdomain.com/api/connectors/callback?provider=google_drive`
6. Click **Create** and copy the **Client ID** and **Client Secret**

### Step 3: Configure Environment Variables

Add to your backend `.env` file:

```env
GOOGLE_CLIENT_ID=your-google-client-id
GOOGLE_CLIENT_SECRET=your-google-client-secret
```

Add to your frontend `.env` file:

```env
VITE_GOOGLE_CLIENT_ID=your-google-client-id
```

| Variable | Description | Required |
|----------|-------------|----------|
| `GOOGLE_CLIENT_ID` | OAuth Client ID from GCP Credentials | Yes |
| `GOOGLE_CLIENT_SECRET` | OAuth Client Secret from GCP Credentials | Yes |
| `VITE_GOOGLE_CLIENT_ID` | Same Client ID, used by the frontend to show the Google Drive option | Yes |

<Callout type="warning" emoji="⚠️">
Make sure to use the same Google Client ID in both backend and frontend configurations.
</Callout>

### Step 4: Restart and Use

Restart your application, then go to the upload section in DocsGPT and select **Google Drive** as the source. You'll be redirected to Google to sign in, then can browse and select files to process.

</Steps>

## Troubleshooting

- **Option not appearing** — Verify `VITE_GOOGLE_CLIENT_ID` is set in the frontend `.env`, then restart.
- **Authentication failed** — Check that the redirect URI matches exactly, including `?provider=google_drive`. Ensure the Google Drive API is enabled.
- **Permission denied** — Verify the OAuth consent screen is configured and the user has access to the target files.
- **Files not processing** — Check backend logs and verify that backend environment variables are correctly set.

For production deployments, add your actual domain to the OAuth consent screen and authorized origins/redirect URIs.
