Character Appearance API Does not work

Error fetching from https:// us.api.blizzard. com/profile/wow/character/deviate-delight/{charactername}/appearance?namespace=profile-classic1x-us&locale=en_US&access_token={accessToken}

{ code: 403, type: ‘BLZWEBAPI00000403’, detail: ‘Forbidden’ }

(Spaces included because links aren’t allowed) No matter what I do I can’t get the data to display for appearance. I can use the same auth token for any other request, but appearance is forbidden. Any help is greatly appreciated.
