This is an important limitation to be aware of: Session Start and Session End events are virtual events â they are computed by Mixpanel at query time within the UI and are not stored as actual events in your data store.
Because of this, they cannot be exported or queried via the API, including JQL. As the documentation states:
"These virtual events do not count toward your data allowance [...] they do not appear in your raw events list and cannot be exported via the API, as they are not stored as actual events in your data store." [Sessions FAQ]
So there is no alternative event name you can use in JQL to access Session Start/End â they simply don't exist as raw events to query against.
Alternatives
Since JQL is also currently in maintenance mode, the recommended alternatives for getting your data are: [JQL docs]
In-app reporting: Use the Core Reports (Insights, Funnels, Flows) where Session Start/End events are fully supported
Query API: For other reporting needs
If you need session-like data via API, you would need to reconstruct sessions yourself from the raw events using your own logic (e.g., grouping events by user with a 30-minute inactivity timeout).
