ordercreated

OrderCreated, sometimes written as orderCreated, is an event emitted by an e-commerce platform or order management system when a new order has been created. It signals the transition from a draft or pending state to a persisted, confirmed record and is typically emitted after validation and saving of the order data.

The event payload usually contains key details about the order. Common fields include an orderId, customerId or a flag indicating a guest checkout, a timestamp, and an items array with productId, quantity, and unitPrice. Totals such as subtotal, tax, shipping, discounts, and grandTotal, along with currency, are often included. The payload may also carry shipping and billing addresses, chosen shipping method, and the initial payment status or token. Depending on privacy and security requirements, sensitive data may be redacted or omitted.

Usage and delivery models vary, but the event is commonly delivered via webhooks, an internal event bus, or message queues (for example, pub/sub, Kafka, or RabbitMQ). It enables downstream processes such as inventory reservations, payment processing, fraud checks, order fulfillment, shipping, and customer notifications. Naming conventions differ across platforms, with variants like orders/create or ORDER_CREATED in addition to orderCreated.

Design and reliability considerations include ensuring idempotent processing to handle duplicate events, verifying the event source, and including an idempotency key or eventId. Architects should consider event ordering (orderCreated should precede updates or cancellations) and handle eventual consistency and retries gracefully. In practice, orderCreated is a foundational trigger in event-driven architectures, enabling automation, integration, and analytics across systems.
