Additional Technical Considerations

​

Idempotency & Duplicate Prevention

POST /api/v1/bookings
Idempotency-Key: req_abc123xyz

201 Created
{booking details}

200 OK
{same booking details}

• Valid for at least 24 hours
• Unique per request (UUID v4 recommended)
• Server returns same response for duplicate keys
• 409 Conflict allowed if key reused with different payload

​

Batch Operations

POST /api/v1/availability/batch

{
  "queries": [
    {
      "query_id": "q1",
      "service_type": "inspection",
      "start_time": "2025-11-01T09:00:00Z"
    },
    {
      "query_id": "q2",
      "service_type": "inspection",
      "start_time": "2025-11-01T10:00:00Z"
    }
  ]
}

{
  "results": [
    {
      "query_id": "q1",
      "available": true,
      "slots": []
    },
    {
      "query_id": "q2",
      "available": false,
      "reason": "provider_unavailable"
    }
  ]
}

Internationalization

• Support Accept-Language header
• Localize error messages
• Respect locale-specific date/time formats
• Handle multi-currency pricing

GET /api/v1/availability
Accept-Language: es-MX

​

Testing Checklist

• All API endpoints functional and documented
• Authentication working (OAuth, API keys, etc.)
• Webhooks delivering successfully with retries
• Error responses follow documented format
• Rate limiting working as specified
• Idempotency keys preventing duplicates
• Timeout handling is graceful
• SSL/TLS certificates valid
• CORS policies correct (if applicable)
• Health check endpoints responding
• Monitoring and alerting configured
• Sandbox and production environments separated
• Load testing passed at expected volume
• Security scan passed (OWASP, penetration test)
• Disaster recovery tested
• Runbook documented for common issues

​

Summary

• Architecture: Real-time API-first workflows with explicitly documented timeout, retry, and fallback behavior
• Security: Strong authentication, scoped credentials, encrypted transport, and risk-appropriate testing
• APIs: RESTful JSON design, webhook support strongly preferred, detailed schemas provided
• Reliability: Agreed latency and availability targets with robust error handling and retry logic
• Support: Named owners, escalation paths, monitoring, and change-management expectations
• Timeline: Project-specific phases for design, implementation, testing, and controlled rollout

1. Review and confirm API specification alignment
2. Establish sandbox access and credentials
3. Schedule kickoff meeting and regular sync cadence
4. Begin Phase 1 discovery activities
