Enable Chat Completions Endpoint

OpenClaw needs to expose an API endpoint for ElevenLabs.

Edit your config:

openclaw config edit

Find the gateway section and add:

{
  "gateway": {
    "http": {
      "endpoints": {
        "chatCompletions": {
          "enabled": true
        }
      }
    }
  }
}

Save and restart OpenClaw:

openclaw restart
7

Expose OpenClaw with ngrok

ElevenLabs needs to reach your OpenClaw. ngrok creates a public URL.

Install ngrok:

brew install ngrok

(Or download from ngrok.com)

Start ngrok tunnel:

ngrok http 18789

You'll see output like:

Forwarding  https://abc123.ngrok.io -> http://localhost:18789

Copy that URL (abc123.ngrok.io part) - you need it next.

Keep this terminal open!

8

Create ElevenLabs Agent

Two options: Manual setup or API (your coding agent can do this).

Option A: Manual Setup

  1. Go to ElevenLabs Agents
  2. Click "Create New Agent"
  3. Under LLM settings, select "Custom LLM"
  4. Set URL to: https://YOUR-NGROK-URL.ngrok.io/v1/chat/completions

Where to find OpenClaw token:

cat ~/.openclaw/openclaw.json | grep token

Option B: API Setup (Advanced)

Ask your OpenClaw chat agent to set this up:

Install ElevenLabs integration using my API key: sk-...

It will handle the API calls for you.

Common Issues & Fixes

Issue: "Connection refused"

Fix: Check ngrok is running and URL is correct:

curl https://YOUR-NGROK-URL.ngrok.io/v1/chat/completions

Should return JSON, not error.

Issue: No voice response

Fix:

  1. Check ElevenLabs API key is valid
