Yes, they’re both using the same data range and the parameters match where applicable. At the moment I can see that ListOrders API call seems to be producing a seemingly likely quantity of orders so I’m thinking that this may be the one to go for. But I would like to know exactly what all those report types in the orders category are for and what the data is they should be returning.
So a my schedule for GET_ORDERS_DATA appears in the Seller Central Portal “Order Reports” page and it states there that the report is for “seller-fulfilled orders only”. This makes complete sense now as to why this report contains so little data. I can now see what the description in the MWS documentation ReportTypes page means! I am beginning to get a slightly clearer picture, I think!
This begs the question is the ListOrders API call only returning data for Amazon fulfilled orders or does it contain the “seller-fulfilled” ones as well?
What we are looking for is to get the same data as in Seller Central Portal --> Reports --> Business Reports --> Detail Page Sales and Traffic . Is this even possible or does Amazon keep it best APIs for internal use only?
