Step 1: Copy your assets
Navigate to app.liveavatar.com. The system automatically detects any existing HeyGen avatars or knowledge bases and creates copies in your LiveAvatar account.
Individual voices cannot currently be migrated. Also, changes made in either platform will not sync — these are independent copies.
Step 2: Transition your implementation
Subscription
If you don’t have an existing LiveAvatar subscription, you’ll receive a temporary 30-day trial to test during the transition.
API changes
Update all API calls from HeyGen endpoints to LiveAvatar endpoints. Key changes:
Session initialization — simplified from 3 calls to 2:
| HeyGen (old) | LiveAvatar (new) |
|---|
| Create Session Token → New Session → Start Session | Create Session Token → Start Session |
| HeyGen (old) | LiveAvatar (new) |
|---|
repeat endpoint | avatar.speak_text event |
chat endpoint | avatar.speak_response event |
interrupt endpoint | avatar.interrupt event |
- Close Session → Stop Session
- List Sessions (Active/History) → single List Sessions endpoint (use
type parameter)
- Knowledge Base → renamed to Context
- Avatar listing split into List Public Avatars and List User Avatars
Recommended pattern
Create the session token on your backend, pass the session start data to your client, and let users start the session on your frontend.
Step 3: Clean up HeyGen
After migrating, cancel your HeyGen subscription. LiveAvatar pricing is significantly cheaper on a per-minute basis.
