Architecture
The following figure provides an overview of the Qlik Sense Proxy Service (QPS) API architecture.
APIs implemented by the Proxy
Personal API
The Personal API is used by the browser to query session information, to get the login or logout URI, and to log out the user. See Personal API.
Proxy (Ticket) API
The Proxy (Ticket) API is used by the External Authentication module for generating a ticket and injecting session attributes. See Ticket.
Proxy (Error logging) API
The Proxy (Error Logging) API is used by external modules to add error logging that is injected into the Proxy logs. See Error logging.
Proxy (Session) API
The Proxy (Session) API is used by external modules to get, add, and delete Proxy sessions. See Session.
Proxy (User) API
The Proxy (User) API is used by external modules to get and delete Proxy sessions for a specific user. See User.
APIs implemented by external modules
Session module API
The Session module API is implemented by the external session module. This API is used by the Proxy to get, add, and delete Proxy sessions by session or by user (a mirroring of the Proxy (Session) and the Proxy (User) APIs). See Session module API.
Load Balancing module API
The Load Balancing API is implemented by the external Load Balancing module. This API is used by the Proxy to get a prioritized list of engines for load balancing. See Load balancing module API.
