Posti also provides functionality to receive tracking codes and print parcel labels for your shipping parcels.

Store your warehouse info

Please contact Posti to provide information about your warehouses which are going to be used for Store shipping.

Store your products

Add products to your catalog. Refer to Products API for full fields description.

Make orders

Place an order from your webstore for the existing products by executing a PUT request to Orders API. Orders will be routed to Posti’s warehouse system or external warehouse systems for shipping. Separate order lines can be routed to different warehouses based on warehouse balance and prioritization. You can agree on warehouse prioritization and certain splitting details with Posti. In cases where your order could not be routed to any warehouse, an email will be sent to your support email address.

Orders API will return a status code 200 to confirm that an order has been successfully placed.

Register a shipment and receive a parcel label

Once your warehouse has received a notification about the new order, they will pick and collect requested items. They will register a new shipment through Shipments API and receive a tracking code and a parcel label in response.
