Installation

pip install django-brevo-analytics

Quick Start

1. Add to INSTALLED_APPS

INSTALLED_APPS = [
    # ...
    'rest_framework',
    'corsheaders',
    'brevo_analytics',
]

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',  # Add at top
    # ... other middleware
]

2. Configure Settings

# Django REST Framework
REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAdminUser',
    ],
}

# CORS (adjust for production)
CORS_ALLOWED_ORIGINS = [
    "http://localhost:8000",
]

# Brevo Analytics Configuration
BREVO_ANALYTICS = {
    'WEBHOOK_SECRET': 'your-webhook-secret',  # From Brevo dashboard
    'API_KEY': 'your-brevo-api-key',          # Optional, for bounce enrichment
    'ALLOWED_SENDERS': [                       # Filter emails by sender
        '[e-mail]',
    ],
}

3. Run Migrations

python manage.py migrate brevo_analytics

4. Include URLs

# your_project/urls.py
urlpatterns = [
    path('admin/', admin.site.urls),
    path('admin/brevo_analytics/', include('brevo_analytics.urls')),
]

5. Set Up Brevo Webhook

Configure webhook in Brevo dashboard:

• URL: https://yourdomain.com/admin/brevo_analytics/webhook/
• Events: All transactional email events
• Add webhook secret to settings

6. Access Dashboard

Navigate to /admin/brevo_analytics/brevomessage/ (requires staff permissions)

Management Commands

Import Historical Data

python manage.py import_brevo_logs /path/to/brevo_logs.csv

Options:

• --dry-run: Preview import without saving
• --clear: Clear existing data before import

Verify Statistics

python manage.py verify_brevo_stats

Compares local statistics with Brevo API to ensure data accuracy.

Architecture

Django-Native Design

• Models: Data stored directly in PostgreSQL via Django ORM
• JSONField Events: Email events stored as JSON array for optimal performance
• Denormalized Stats: Pre-calculated statistics for fast queries
• Cached Status: Current status field for efficient filtering

REST API

• Django REST Framework: 6 API endpoints for dashboard and analytics
• Admin-Only Access: All endpoints require Django admin permissions
• Serialized Data: Optimized JSON responses for Vue.js frontend

Vue.js SPA

• Composition API: Modern Vue 3 with reactivity
• Hash-based Routing: Client-side routing without server config
• Modal Overlays: Email details shown in modals, no page reloads
• Responsive Design: Mobile-friendly interface

Security

• HMAC Webhook Validation: Verify webhook signatures from Brevo
• Admin Permissions: All views require Django staff access
• CORS Protection: Configurable CORS for API endpoints
• SQL Injection Safe: Django ORM prevents SQL injection

Configuration Options

Required

• WEBHOOK_SECRET: Secret key from Brevo webhook configuration

Optional

• API_KEY: Brevo API key for bounce enrichment and blacklist management
• ALLOWED_SENDERS: List of sender emails to filter (for multi-client accounts)
• CLIENT_UID: UUID for tracking client (defaults to generated UUID)

Data Flow

Brevo → Webhook → Django Model → PostgreSQL
                       ↓
                   DRF API
                       ↓
                  Vue.js SPA

Multi-Client Support

For shared Brevo accounts, use ALLOWED_SENDERS to filter:

• Emails with matching sender: always included
• Emails without sender info: included only if in local database
• This prevents showing other clients' data

Development

Clone Repository

git clone https://github.com/guglielmo/django-brevo-analytics.git
cd django-brevo-analytics

Install Dependencies

pip install -r requirements.txt

Run Tests

python manage.py test brevo_analytics

Troubleshooting

Webhook Not Working

• Verify WEBHOOK_SECRET matches Brevo configuration
• Check webhook URL is publicly accessible
• Review Django logs for HMAC validation errors
• Test webhook with curl to check connectivity

Empty Dashboard

• Run import_brevo_logs to import historical data
• Verify webhook is configured and receiving events
• Check ALLOWED_SENDERS filter isn't too restrictive
• Ensure migrations have been applied

Blacklist Management Not Working

• Add API_KEY to BREVO_ANALYTICS settings
• Verify API key has correct permissions on Brevo
• Check network connectivity to Brevo API
