User has to establish a valid connection in order to interact with Stat through Web Services. Connections are validated the same way a normal login into the Web Client is validated. Upon successful connection, a valid Connect ID is returned to the user, which will be used in subsequent method calls to validate user's connection. Also proper rows are written into CONNECTION_MGMT and CONNECT_HIST tables. A list of valid connections is stored on the server and the connection is refreshed each time a valid Web Service Method is executed. This connection will have to be either closed by User or it will expire after a time-out period.
