Hello,
We have an old OAuth integration and have recently migrated over to oauth.battlenet.com / oauth.battlenet.com.cn respectively. On the Global side everything is working fine, but on the CN side we’re getting “401 - Bad client credentials” when accessing the authorize URL. That is to say:
https://oauth.battle.net/authorize?client_id=<our_client_id>&redirect_uri=<...>works as expectedhttps://oauth.battlenet.com.cn/authorize?client_id=<our_client_id>&redirect_uri=<...>fails with a 401
Interestingly enough the URLs also behave differently when omitting the redirect_uri: the global /authorize endpoint responds with “400 - The redirect_uri parameter must be a valid URI”, and the CN version responds with the same “401 - Bad client credentials”. I can get the global endpoint to also respond with a 401 if I choose an invalid client id.
This makes me believe that oauth.battlenet.com.cn does not recognize client ids registered in the developer portal. Do we need to recognize a Chinese Client ID somewhere else than the developer portal? Is this a bug?
We’re hoping on a quick resolution as we’ve got a huge set of Hearthstone players trying to log in to our site, after the Hearthstone re-release in China this week.
