HeyGen LiveAvatar provides avatar video in SentiVue Talk.
What you need
This must be a LiveAvatar key, not a regular HeyGen API key. LiveAvatar keys come from a separate console and a standard HeyGen key is rejected.
Getting your credentials
- Sign in at app.liveavatar.com.
- Create an API key and copy it.
Adding the connection
- Go to Connections and choose HeyGen LiveAvatar.
- Paste your API key.
- Save. SentiVue Talk checks the key against LiveAvatar straight away and tells you if it was rejected.
Choosing an avatar
Once connected, open the Avatar step on Model Configurations and pick an avatar. The picker has two tabs:
- Public — HeyGen’s stock avatar library.
- My avatars — avatars belonging to your LiveAvatar account.
Each avatar shows a preview so you can choose without handling raw avatar IDs.
Picking an avatar is not enough on its own — see Avatar for the toggles that turn it on for embeds, demo links, and the test panel.
