The Item APIs allow external systems to create, retrieve and delete items in Leanafy. Items must be created before they can be added to Orders or ARNs. This ensures that inventory and order management processes function correctly.

Orders, also known as Purchase Orders, are received by Leanafy through external integrations or created manually by warehouse operators. Once an order enters into Leanafy, warehouse operators can allocate inventory, pick, pack, ship, and fulfill the order.

ARN, Advance Receiving Note, is a document created in Leanafy before the actual receipt of goods, typically based on advance shipment information provided by a supplier.
An ARN can be created using the Create ARN API. Once the ARN is partially or wholly received, the received quantity details will be available on the item level, which can be retrieved using the Get ARN by ID API or Get All ARNs API.
