Hey Developers,
We are planning to remove this API endpoint shortly This endpoint has been disabled:
https://www.roblox.com/Groups/GetPrimaryGroupInfo.ashx
It is not possible to call this endpoint using HttpService, but we are posting this notice because some developers may be hitting this endpoint using their own web servers. If you are using it, please switch to this newer endpoint:
https://groups.roblox.com/docs#!/PrimaryGroup/get_v1_users_userId_groups_primary_role
