We have an ongoing game use playfab heavily from authenticate to player data storage... Now we need to integrate new authentication gateway. End of the day after player link to new login account we will have an uuid link to player's current playfab_id (LinkServerCustomId) . After that our server will call LoginByServerCustomId to return the session ticket to user.
But the problem is some of old additional backend of the game also use ServerCustomId for some purpose and they are not ready to allow us to override. So is there anyway to work around? the final goal is return session ticket to the client.
