I am having issues submitting shipment confirmations, what can I do?

Select to expand the answer.

Vendors can verify the status of their shipment confirmations via Vendor Central > Orders > Direct Fulfillment Orders or using the Direct-fulfillment Transaction Status API. Allow the system up to 10 min to see the status once submitted.

Here are some common errors a vendor might face when submitting this API call:

  • You should use this API to confirm shipment of an order within 4 hours after the order has shipped from your warehouse.
  • For floor denied shipments, send “shipmentStatus” field value as “FLOOR_DENIAL”.
  • All the purchase order line items should be present in the shipment confirmation. Partial order fulfillment is not allowed. Vendors should reject the order as floor denial if any of the line items are not available to fulfill.
  • “itemSequenceNumber” for an item should be same as received in order message.
  • Either “buyerProductIdentifier” or “vendorProductIdentifier” is mandatory to send in the shipment confirmation. You need to send the same value as received in purchase order.
  • For vendor own carriers, sending “scacCode” is mandatory.
  • If the shipment label is provided by Amazon, then container section is optional since Amazon has access to the package information. Items section is mandatory to submit.

What kind of labels are available to download?

Can the package/items data be omitted from Shipping label request?

Select to expand the answer.

Yes, Shipping lables can be requested by providing only the minimal 3 fields, order id, vendor code SellingParty and warehouse code shipFromParty. Amazon will get the information about items from catalogue in this order and create a shipping label. If there is custom information like multi box scenario, then the package loop is mandatory to request labels so they are created as per dimensions provided.

Shipping labels are not available when making the GET call?

Select to expand the answer.

Shipping labels must be created first by making a POST call with the information about the order. Only if that request succeeds, a label will be available in the back end to request via the GET call. Make sure the POST call is made first, the status is checked via the transaction status API before trying to download a label via GET call.
