2. Setup & Configuration

Environment Setup

Install the required dependencies for your platform:

Python
pip install requests
Node.js
npm install axios
Configuration

Store your API credentials securely:

# .env file
FRAUDGUARD_API_TOKEN=your_token_here
FRAUDGUARD_API_URL=https://api.fraudguard.com
Security Note: Never commit your API token to version control!

3. Integration Guide

Basic Integration

Follow these steps to integrate FraudGuard into your application:

Step 1: Initialize the Client
from fraudguard import FraudGuardClient

client = FraudGuardClient(api_token="your_token")
Step 2: Perform Fraud Checks
# Check email for fraud
result = client.check_email(email_content)

if result.is_fraud:
    print(f"Fraud detected! Score: {result.score}")
    print(f"Reasons: {result.fraud_indicators}")
else:
    print("Email appears legitimate")
Step 3: Handle Transactions
# Submit transaction for analysis
transaction = client.submit_transaction(
    sender_id="user123",
    receiver_id="user456",
    amount=150.00,
    description="Payment"
)

if transaction.requires_review:
    # Hold transaction for manual review
    notify_admin(transaction.id)
else:
    # Process transaction
    process_payment(transaction)
Advanced Integration
Webhook Setup

Configure webhooks to receive real-time notifications:

POST /api/webhooks
{
    "url": "https://yourdomain.com/webhooks/fraudguard",
    "events": ["fraud.detected", "transaction.flagged"]
}
Batch Processing

For high-volume scenarios, use batch endpoints:

POST /api/fraud-check/batch
{
    "items": [
        {"data_type": "email", "content": "..."},
        {"data_type": "sms", "content": "..."}
    ]
}

4. Testing & Validation

Test Mode

Use test mode to validate your integration without affecting production data:

client = FraudGuardClient(
    api_token="your_token",
    test_mode=True
)
Test Scenarios

Try these test cases:

  • Legitimate email: "Hello, this is a test message"
  • Phishing attempt: "Click here to verify your account immediately!"
  • Suspicious SMS: "You've won ₹1000! Call this number now!"
Validation Checklist
  • API authentication working correctly
  • Fraud detection returning expected results
  • Error handling implemented
  • Rate limiting handled gracefully
  • Webhooks receiving notifications

5. Production Deployment

Pre-Deployment Checklist
  • API tokens stored securely in environment variables
  • Error handling and logging configured
  • Rate limiting implemented in your application
  • Monitoring and alerting set up
  • Backup fraud detection strategy in place
Monitoring

Monitor these key metrics:

  • API response times
  • Error rates
  • Fraud detection accuracy
  • False positive/negative rates
  • API usage vs. quota
Scaling Considerations
  • Implement caching for frequently analyzed patterns
  • Use async/queue systems for non-blocking fraud checks
  • Consider upgrading to higher tier for better rate limits
  • Implement circuit breakers for API failures
