## Path: / rest / authentication / signinastenant / name

SignIn as a tenant, and return a session ID (sID) to use in subsequent calls to other APIs. *

Note: 1. SignIn as a tenant will not log out original session 2. if your application uses both the SOAP web services API and the REST API, the same session ID can be used in both APIs; you do not need to log in separately to each API.
