Google Analytics Dashboard Plugin for Payload CMS

Display Google Analytics 4 (GA4) metrics directly in your Payload Admin dashboard with beautiful, real-time widgets.

Features

• Analytics Overview: Active users, total users, page views, event count, and key events with a 7-day trend chart
• Top Pages: Most visited pages with view counts
• Active Users: Real-time active users with top 3 locations (updates every 60 seconds)
• Channel Groups: Sessions by traffic channel with percentage breakdown
• Dark Mode Support: All widgets work seamlessly with Payload's light and dark themes
• Demo Mode: Display mock data for screenshots and videos without exposing real analytics

Installation

1. Install the Plugin

npm install @zubricks/plugin-google-analytics
# or
yarn add @zubricks/plugin-google-analytics
# or
pnpm add @zubricks/plugin-google-analytics

2. Re-export the API Routes

The plugin ships three API route handlers. Rather than copying them into your app (which goes stale on every plugin update), create three thin route files that re-export the handlers from the package. Updates then flow in automatically when you bump the plugin version.

Create these files in your Next.js app:

// src/app/api/analytics/pageviews/route.ts
export { GET } from '@zubricks/plugin-google-analytics/api/pageviews'

// src/app/api/analytics/active-users/route.ts
export { GET } from '@zubricks/plugin-google-analytics/api/active-users'

// src/app/api/analytics/channel-groups/route.ts
export { GET } from '@zubricks/plugin-google-analytics/api/channel-groups'

These files never need to change again — the handler logic lives in the package.

3. Google Cloud Setup

Enable Google Analytics Data API

1. Go to Google Cloud Console
2. Select or create a project
3. Navigate to "APIs & Services" > "Library"
4. Search for "Google Analytics Data API"
5. Click "Enable"

Create Service Account

1. Go to "APIs & Services" > "Credentials"
2. Click "Create Credentials" > "Service Account"
3. Give it a name (e.g., "Payload Analytics Reader")
4. Click "Create and Continue"
5. Grant the role "Viewer" (optional)
6. Click "Done"

Download Service Account Key

1. Click on the service account you just created
2. Go to the "Keys" tab
3. Click "Add Key" > "Create new key"
4. Choose "JSON" format
5. Click "Create" (the JSON file will download automatically)

2. Google Analytics Setup

Add Service Account to GA4

1. Go to Google Analytics
2. Navigate to "Admin" (gear icon in the bottom left)
3. In the "Account" column, click "Account Access Management"
4. Click the "+" button in the top right
5. Click "Add users"
6. Enter the service account email (found in the JSON file as client_email)
7. Select "Viewer" role
8. Uncheck "Notify new users by email"
9. Click "Add"

Get Your Property ID

1. In Google Analytics, go to "Admin"
2. In the "Property" column, click "Property Settings"
3. Copy your "Property ID" (it looks like 123456789)

3. Configure Environment Variables

Add the following to your .env or .env.local:

# Google Analytics Property ID (from GA4 property settings)
GA_PROPERTY_ID=123456789

# Base64 encoded Google Service Account credentials
# To encode the JSON file, run this command in your terminal:
# cat path/to/your-service-account-key.json | base64
GA_CREDENTIALS=<base64-encoded-json>

# Optional: Enable demo mode (default: false)
GA_USE_DEMO_DATA=false

Encoding the Service Account JSON

Run this command to base64 encode your service account JSON file:

cat path/to/your-service-account-key.json | base64

Copy the output and paste it as the value for GA_CREDENTIALS.

macOS/Linux shortcut to copy directly to clipboard:

cat path/to/your-service-account-key.json | base64 | pbcopy

5. Add Plugin to Payload Config

import { googleAnalytics } from '@zubricks/plugin-google-analytics'

export default buildConfig({
  // ... other config
  plugins: [
    googleAnalytics({
      // Optional: Configure which widgets to enable
      enabledWidgets: ['analytics-overview', 'top-pages', 'active-users', 'channel-groups'],

      // Optional: Define default dashboard layout
      defaultLayout: [
        {
          widgetSlug: 'analytics-overview',
          width: 'medium',
        },
        {
          widgetSlug: 'top-pages',
          width: 'full',
        },
        {
          widgetSlug: 'active-users',
          width: 'x-small',
        },
        {
          widgetSlug: 'channel-groups',
          width: 'x-small',
        },
      ],

      // Optional: Override environment variables
      // propertyId: '123456789',
      // credentials: 'base64-encoded-json',
      // useDemoData: false,
    }),
  ],
})

Configuration Options

Plugin Config

| Option | Type | Default | Description | |--------|------|---------|-------------| | propertyId | string | process.env.GA_PROPERTY_ID | Google Analytics GA4 Property ID | | credentials | string | process.env.GA_CREDENTIALS | Base64 encoded service account JSON | | useDemoData | boolean | process.env.GA_USE_DEMO_DATA === 'true' | Enable demo mode to display mock data | | enabledWidgets | array | All widgets | Array of widget slugs to enable | | defaultLayout | array | undefined | Default dashboard layout configuration |

Available Widgets

• analytics-overview - Metrics overview with trend chart (minWidth: medium)
• top-pages - Top 10 most visited pages (minWidth: medium)
• active-users - Real-time active users by location (minWidth: x-small)
• channel-groups - Sessions by traffic channel (minWidth: x-small)

Widget Width Options

• x-small: 25% width
• small: 33.3% width
• medium: 50% width
• large: 66.7% width
• x-large: 75% width
• full: 100% width

Demo Mode

Perfect for creating screenshots, videos, or development without exposing real analytics data.

Enable demo mode in your environment variables:

GA_USE_DEMO_DATA=true

Or in the plugin configuration:

googleAnalytics({
  useDemoData: true,
})

When enabled, all widgets display realistic mock data without connecting to Google Analytics.

API Endpoints

The plugin provides three API endpoints:

• GET /api/analytics/pageviews - Analytics overview and top pages data
• GET /api/analytics/active-users - Real-time active users
• GET /api/analytics/channel-groups - Sessions by channel

All endpoints automatically respect the GA_USE_DEMO_DATA environment variable.

Troubleshooting

"Google Analytics not configured" error

Make sure both GA_PROPERTY_ID and GA_CREDENTIALS environment variables are set correctly.

"Failed to get access token" error

1. Verify your service account JSON is properly base64 encoded
2. Check that the service account has been added to your Google Analytics property
3. Ensure the Google Analytics Data API is enabled in your Google Cloud project

"GA4 API request failed" error

1. Verify your GA_PROPERTY_ID is correct
2. Check that the service account has "Viewer" access to the property
3. Make sure you're using a GA4 property (not Universal Analytics)

Data not showing

1. Ensure your website has the GA4 tracking code installed
2. Verify there's actual traffic data in your GA4 property
3. Check the browser console for any error messages
4. Make sure you've restarted your development server after adding environment variables

Widgets not appearing

1. Check that the plugin is added to the plugins array in your Payload config
2. Verify the ComponentPath can resolve correctly
3. Check browser console for any import errors

Development

Running Locally

The plugin automatically uses environment variables by default, making it easy to develop locally:

1. Set up your .env.local with GA credentials
2. Add the plugin to your Payload config
3. Run your development server
4. Widgets will appear in the dashboard
