Interacting with a session
After having started a session using one of the the /api/v2/start
endpoints endpoints, its initial page contents may be obtained via a POST
to /api/v2/session/{sessionId}/load
. The result of this call is the full page model, necessary for initial rendering of the page. Subsequently, events may be submitted to the runtime via a POST
to /api/v2/session/{sessionId}/event
, resulting in a response containing all changes (add, update, delete). In Blueriq each session may be part of a hierarchy of sessions. For example, in a a DCM application application, the session of a flow widget is a child session of the main dashboard session. An event in one session may cause changes in other sessions if Portal Messages are thrown. Therefore, the response of of /api/v2/session{sessionId}/event
endpoint endpoint will contain changes in all sessions in the heirarchy. An example response containing the changes:
