I am trying to use Multiple Marketplace ID to request a FBA inventory manage report (GET_FBA_MYI_UNSUPPRESSED_INVENTORY_DATA) for US and Canada.
I put value “ATVPDKIKX0DER” and A2EUQ1WTGCTBG2 in the marketplaceIdArray.
But, it only gives me the report for the first marketplace in the marketplaceIdArray.
May I know why?
