Step 1 - Create a listing

Before sending an item to the Amazon Fulfillment Network (AFN), programmer needs to create a listing in Amazon's catalog. This is true regardless of whether or not one intends to sell on Amazon's web site or through other sales channels. It is mandatory to mark items as AFN i.e. Amazon Fulfillment Network that tags an item to be fulfilled by Amazon. SubmitFeed operation of the Feeds API is used to mark an item as AFN.

 Step 2 – Create an inbound shipment plan

CreateInboundShipmentPlan operation of the Inbound Shipment API is used to create an inbound shipment plan. An inbound shipment plan groups into discrete shipments the items to be sent to the Amazon Fulfillment Network.

By submitting the CreateInboundShipmentPlan operation, Amazon is provided with key information about the items to be sent. In this operation list of sellerSku, quantity, ASIN, condition of the item and the from-address are sent.

Step 3 – Create / Update inbound shipment

For each shipment returned by the CreateInboundShipmentPlan operation, create an inbound shipment. An inbound shipment is created by submitting the CreateInboundShipment / UpdateInboundShipment operation of the Inbound Shipment API section.

 One should check for the to-address given by inbound shipment plan, to check for any active shipment on the same address. If the active shipment is not present then the CreateInboundShipment operation is used and if the active shipment is there, then the UpdateInboundShipment operation is used.

The shipmentId, FCCD, to-address generated by inbound shipment plan, and also the list of sellerSku and the quantity of each sellerSku as passed to Amazon API.  On inbound shipment creation/updation, indicates to Amazon are created to denote arrival of items to AFC (Amazon fulfillment center).

Step 4 – Transport Shipment

Before sending the shipment in the transport state, developer needs to specify the shipment box weight, height, width and length and then we can mark the shipment in the transport state. Here we need to keep in mind that the weight and dimension of the box specified must be correct, if there is difference then the shipment will we canceled and if this type of mistake occurs frequently then your account might be blocked by the amazon.

Step 5 – Estimating Shipment

When the shipment is successfully transported then the next step is to estimate the shipment, means to calculate the cost of the shipment based on the weight and the dimension of the shipment box. For calculating the shipment cost GetTransportContent operation is used.

Step 6 – Confirm Estimate Shipment Cost

User decides whether calculated cost is feasible for him or not. If the user confirms the cost, the shipment is marked as shipped and the user needs to pay to the Amazon. If the user cancels, shipment is not shipped and stays in the estimated status and user needs to pay that shipment until he confirms the shipment cost.

Step 7 – Download Shipment Label

Use the GetUniquePackageLabel operation to request unique shipping labels for your inbound shipments. This option is active once shipment is confirmed. User receives PDF file with all details regarding shipment.  Download shipment label option is available for each shipment created by User on confirmation. User can also download this shipment label even after a week or month of his shipment process. This helps to ensure that the shipment is processed at the Amazon fulfillment center quickly and accurately.
