Hi everyone,
I’m facing an issue with Vapi custom tools + n8n webhook. The agent is calling the custom tool successfully, but no data is being forwarded to the webhook, and Vapi returns a “No result returned” error.
It looks like the tool invocation happens, but the request body is either empty or not reaching n8n, so the agent never receives a response.
If anyone has dealt with tool → webhook data forwarding issues in Vapi, I’d appreciate any pointers on what to check (tool schema, request format, webhook response, etc.).
