Immediately terminate a running workflow execution. This is a hard stop — the workflow will not execute cleanup logic and cannot be resumed. Use cancel instead if you need graceful shutdown.
​
wfId
string
required
The workflow ID to terminate
​
reason
string
Human-readable reason for termination. Will be recorded in workflow history.
​
run_id
string
Specific run ID to terminate. If omitted, terminates the most recent run.
