Hi @slakshmanan ,

To stop or interrupt a running notebook, select the interrupt button in the notebook toolbar. You can also select Run > Interrupt execution, or use the keyboard shortcut I I.

And if you're going to use SQL warehouse then to terminate a long-running query started by you or another user:

1. View query history.

2. Click the name of a query.

3. Next to Status, click Cancel.

I don't think that exist such an endpoint yet. At least, I couldn't find it in documentation.
