First, you retrieve information about the local player that is currently logged in. The account ID of this local player is used as a parameter for all other Online Services plugin operations. Once you know how to obtain this information, you can perform all other Online Services functions. This guide uses the Online Services Null plugin. Users are automatically registered with the Null services so they do not need to call a login function. As a result, you do not need to make an explicit login call, but you do need to obtain the online information about local users from the online services.
