Anyone running Vapi + n8n? Hitting major issues with Structured Outputs
Hey everyone — looking for some help or confirmation here. I built an AI cold caller using Vapi, with n8n as the backend (webhooks, call processing, Sheets, follow-ups, etc.). The calling itself works great, but I’m running into a wall with Structured Outputs. Setup: Using Vapi’s new Structured Outputs (not deprecated structured data) 6 outputs configured (lead qualification, call outcome, summary, appointment info, etc.) Outputs show correctly in the Vapi dashboard call logs Deprecated Summary / Structured Data are disabled Assistant is patched with artifactPlan.structuredOutputIds Issue: When I fetch calls in n8n via: GET https://api.vapi.ai/call/{callId} the response does not include artifact or artifact.structuredOutputs — only transcript, recording URL, status, etc., even though the dashboard shows the structured outputs for that same call. Has anyone successfully pulled Structured Outputs via the API? Is this a known limitation or bug, or is there a workaround people are using? This is blocking a production n8n workflow, so any insight would be appreciated.
