Submit a new order to the PAR Brink POS cloud API and poll for its kitchen status

Steps

1. Access the Brink API portal at brinkapiportal.brinkpos.net and review the SOAP-based API contract; note that Brink uses SOAP over HTTPS rather than REST for core POS operations
2. Authenticate to the Brink API service using the credentials provided during integration onboarding and call the Ordering service's CalculateOrder method to validate the order and retrieve pricing before submission
3. Submit the order by calling the appropriate Ordering service method with the full order payload including items, modifiers, tender type, and location identifiers
4. Poll the order status using the corresponding retrieval method; follow Brink's best-practice recommendation of making 5 to 10 concurrent calls with a sleep interval of 2 to 3 minutes between polling cycles
5. Always submit DateTime parameters in UTC format; the GetShifts call and other time-sensitive methods have built-in logic that will not return data correctly if datetime values are not in UTC
6. Handle errors from the API response envelope and implement a dead-letter queue for failed submissions to avoid silent order loss
