Pre-Launch Checklist
Security Review
- Credentials Management: Confirm API credentials are stored in environment variables
- HTTPS Only: Ensure all API calls use HTTPS
- Token Security: Implement secure token storage and automatic refresh
- Webhook Validation: Verify webhook signature validation is implemented
- Error Logging: Ensure sensitive data (tokens, passwords) is not logged
Error Handling
- Network Failures: Implement retry logic with exponential backoff
- Graceful Degradation: Handle API downtime gracefully
- User Feedback: Provide clear error messages to users
- Monitoring: Set up alerts for critical errors
Webhook Setup
- Endpoint Configured: Production webhook URL is registered
- Idempotency: Handle duplicate webhook deliveries
- Async Processing: Process webhooks asynchronously to avoid timeouts
- Retry Handling: Implement retry logic for failed webhook processing
Compliance
- Data Privacy: Ensure GDPR/NDPR compliance for user data

Production Credentials
To obtain production API credentials:- Complete Integration Testing: Ensure all test scenarios pass
- Submit Go-Live Request: Email hello@fincode.co.uk with:
- Company name and registration details
- Integration completion confirmation
- Expected transaction volume
- Receive Production Access: You’ll receive:
- Production API credentials
- Production base URL:
https://${domain}.fincode.tech - Production webhook configuration
Monitoring & Logging
Recommended Metrics
Track these key metrics to monitor your integration health:- Transaction Success Rate: Percentage of successful transactions
- API Response Times: Monitor for degradation
- Error Rates: Track 4xx and 5xx errors
- Webhook Delivery: Monitor webhook receipt and processing times
Logging Best Practices
- Log all API requests and responses (excluding sensitive data)
- Include correlation IDs for tracing
- Set up alerts for:
- High error rates (>5%)
- Slow response times (>3 seconds)
- Failed webhook deliveries
