Hey, can I copy the assistant options from the dashboard somewhere, if I want to use them to configure an ephemeral assistant? Or do I need to fetch the assistant options using the API?

Yes you can either manually copy the assistant options from the dashboard for temporary use or fetch the configuration via the API for persistent, reusable assistants..

Can I copy the whole JSON object from the dashboard, so I can re-use it in my code for an ephemeral assistant call?

Yes

Cool! Where is the JSON Assistant config in the dashboard? I can't find it.

Vapi doesn’t show the assistant’s JSON config directly in the dashboard, you configure settings through the UI, or use the API to retrieve and update the full JSON.
