Create Order

Create a new OTA Channel Manager order.

The combination of partnerId and sellToOrderReference must be unique; resubmitting the same pair returns 400 Bad Request. Each items entry must reference an existing item — a package item expands into multiple component admissions (and, where configured, coupons), while a non-package item is a single ticket.

The endpoint is asynchronous: it accepts the order, persists it with status = Submitted, and returns immediately. The order is then processed in the background, transitioning through Scheduled → Processing → Issued | Draft | Error. Subscribe to the ota_cm_order_processed webhook to be notified when the order reaches a terminal state, or poll getOrder until status is one of Issued, Draft, or Error.
