Connect N8N workflow to OpenAi Real time voice agent instead of retell ai

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

  • N8N workflow is connected with retell ai via web-hook node in N8N.
  • Is there a way to replace the RETELL AI by OpenAI Real time voice agent

Hey, after checking, unfortunately there isn’t a drop-in replacement you can use for this.

  1. You need to build a lightweight Node.js/Python bridge service.
  2. That service will:

    • Connect to OpenAI Realtime API (via WebRTC or WebSocket; it doesn’t support webhooks).

    • Listen for transcription / agent messages.

    • Forward structured JSON to your existing n8n webhook.

Tag this as Solved, if it helped and let me know if you have more questions :slight_smile:

Hi @krisn0x , thank you for help. I follow what you said and it is working perfectly as I had to create a third party bridge let say and then connect it real time api so it forward all the transcription to n8n workflow, it was hard but it worth it. thank you again
