To access the Address Manager Legacy v1 API, the script or application must log in to Address Manager using an API user account.
All Legacy v1 API implementations must first connect to the Address Manager API service, and then log in to start a session.
To connect to the service, you need the IP address for the Address Manager server. Logging in creates a user session with a timeout limit corresponding to the limit set for all users. API users must also log out after completing required tasks.
