[Help] Outbound Vapi + n8n: Tools (Calendar) not triggering

Hi all,

I'm triggering Vapi outbound calls via n8n. Inbound works fine, but on Outbound, the agent ignores my n8n tools (Calendar/Booking).

**The Blocker:**

When using the `/call` API endpoint, does the `assistantId` automatically inherit the attached tools and Server URL, or do I need to hardcode them explicitly into the API JSON payload?

If anyone has a working outbound JSON payload that successfully calls backend tools, please share.

Stack: Vapi, n8n (Self-hosted).
