Opencell

Overview

The Opencell node for n8n enables integration with the Opencell API, specifically for managing commercial orders. The Order → Validate Order operation allows users to validate a commercial order by its ID. This is useful in business workflows where you need to ensure that an order meets all necessary criteria before further processing, such as fulfillment or invoicing.

Practical Example:
You might use this node after creating or updating an order to confirm its validity within your automated sales or ERP workflow.

  "status": "SUCCESS",
  "message": "Order validated successfully.",
  "orderId": 12345,
  // ...other fields as returned by Opencell
}
