Request tracking with X-Request-ID

You can include your own X-Request-ID header for request correlation:
Best practices:
  • Use a unique value per request (UUID recommended)
  • Include your app name or context for easier debugging
  • The API echoes back your ID in the response X-Request-ID header
  • If you don’t provide one, the API generates a UUID automatically
This is useful for:
  • Correlating requests in your application logs
  • Referencing specific requests when contacting support
  • Tracing requests across your infrastructure
