Chargebee Orders automatically creates orders for your shippable products. This way, a plan or addon with shippable goods will have one or more orders attached to it, each corresponding to a particular shipment. An order would thus keep details such as items to be shipped, the share of invoice amount associated with the shipment, shipping date, status of the shipment, billing/shipping addresses, tracking Id etc.
Orders — along with its API — is designed to integrate with shipping platforms such as ShipStation so that once Chargebee bills your customers and creates orders accordingly, the shipping platform can have the required information to fulfil them.
Changes in Chargebee made to customer records, their subscriptions or invoices etc. often affect the orders associated with them. These impacts are handled automatically and can be communicated to your shipping platform via webhooks.
