403 Forbidden on WoW Classic Profile API with Client Credent

Hello together,

I am consistently receiving a 403 Forbidden error when trying to access the WoW Classic character profile API, even after following all documentation and troubleshooting steps.

Endpoint: GET eu [dot] api [dot] blizzard [dot] com /profile/wow/character/{realm-slug}/{character-name}

Flow Type: Client Credentials Flow

Problem Description: My application successfully obtains an access token from eu [dot] oauth [dot] battle [dot] net / token using the Client Credentials flow and requesting the scope=wow.profile.

However, when this token is used to access a WoW Classic character profile (e.g., namespace=profile-classic-wotlk-eu), the API returns a 403 Forbidden error.

Using the /oauth/check_token endpoint, I can see that the token is being issued with an empty scope array, which is likely the cause of the 403 error. This happens even with a brand new API client.

Steps to Reproduce:

  1. Create a new API Client in the developer portal for Client Credentials.
  2. Request an access token from eu [dot] oauth [dot] battle [dot] net / token with the body grant_type=client_credentials&scope=wow.profile.
  3. The request is successful and returns a token.
  4. Use this token to make a GET request to eu [dot] api [dot] blizzard [dot] com /profile/wow/character/ragnaros/ansraer?namespace=profile-classic-wotlk-eu.

Expected Result: A 200 OK response with the character’s profile data.

Actual Result: A 403 Forbidden response with the body {"code":403,"type":"BLZWEBAPI00000403","detail":"Forbidden"}.

Token Introspection Result (from /oauth/check_token): This is the crucial information from our debugging. It proves the scope is empty.

JSON

{
    "scope": [],
    "exp": 1756035158,
    "authorities": [
        {
            "authority": "ROLE_CLIENT"
        }
    ],
    "client_id": "DEINE-CLIENT-ID"
}

It seems the scope=wow.profile parameter is being ignored when generating a token for the EU region when used against the Classic API. Could someone help me in this?

Thank you!

known issue, been reported been months

and profile-classic-wotlk-eu is not a proper namespace

Okay, thanks for your reply.

What would be the correct namespace for classic?
