Clean up a sandbox when its session is canceled
Canceled plans should not leave a dedicated sandbox running. Have Notis connect the cancellation to the environment reserved for that event.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
Delete Sandbox
Tool to terminate and permanently delete a running E2B sandbox instance. Use when you need to kill a sandbox that is no longer needed. Once terminated, the sandbox cannot be resumed.
Why this helps
A canceled session can leave its sandbox running because cleanup is easy to overlook.
- Prompt cleanup when a session is canceled or deleted.
- Reduce unused running sandboxes.
- Tie the cleanup decision to the original event.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and E2B once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3Tell Notis which canceled events have dedicated sandboxes and how to identify them before deletion.
- 4Pick Event Canceled or Deleted as the trigger and choose where run reports should go.
- 5Test with one real cancellation and a sandbox that is safe to delete.
Questions about this workflow
Can a deleted sandbox be recovered?
No. The E2B Delete Sandbox action permanently terminates the running sandbox, and it cannot be resumed.
What details does the cancellation trigger provide?
It returns minimal data: event ID, summary if available, and cancellation timestamp.
Should every cancellation delete a sandbox?
Only if your instruction can identify a sandbox dedicated to that event and you intend to permanently delete it.
