亚马逊卖家中心 - SP-API - 获取货件标签

Question

I have no previous experience with Amazon MWS so maybe I'm not understanding the whole process flow. Now I'm trying to get labels for shipments I manually created over the Seller Central UI. Shipments I created are successfully fetched (Operation: getShipments) and now I have issue when getting the labels.

Here is my error response from API:

{'errors': [{'code': 'InvalidInput',
   'message': 'Provided SellerCartonIds are not valid: [[FBAxxxxxxxxxU000001]] for Shipment: [FBAxxxxxxxxx]',
   'details': ''}]}

If I print labels from UI FBAxxxxxxxxxU000001 label is printed in pdf - also found out about naming here .

In general, I don't know where to find parameter of package labels PackageLabelsToPrint from GetLabelsDocs , also I'm not sure if this parameter is same as cartonIdList parameter?

Here is response if you don't provide PackageLabelsToPrint query param in request:

{'errors': [{'code': 'InvalidInput',
   'message': "1 validation error detected: Value null at 'cartonIdList' failed to satisfy constraint: Member must not be null",
   'details': ''}]}

I spent a bit of time on this already and it gets a bit annoying.

Thanks!
