We are migrating to new browsing API. During our tests we tried getLegacyItem and GetItem : ie https://api.ebay.com/buy/browse/v1/item/get_item_by_legacy_id and https://api.ebay.com/buy/browse/v1/item/
with the same item using LegacyId or ItemId
The 1st one works, the second does not giving "error 1100, access denied, insufficient privilege".
Both use same oauth token.
Could you help us ?
Thanks.
