HeyGen API key
The key is stored as a server-side secret and never sent to the browser.
HEYGEN_API_KEY is not set
Open Project Settings → Secrets, add a secret named HEYGEN_API_KEY and paste your HeyGen key. Secrets are write-only, so it is entered there rather than in this page — that way the value is never exposed to the client.
Higgsfield (b-roll)
Used to generate supporting visuals. Credentials stay server-side.
Higgsfield credentials are not set
Add a secret named HIGGSFIELD_API_KEY with the value key-id:key-secret from Higgsfield Cloud in Project Settings → Secrets (the separate HIGGSFIELD_API_KEY_ID / HIGGSFIELD_API_KEY_SECRET pair also works). Like the HeyGen key, it stays server-side.
Avatars
Nickname, HeyGen avatar ID, optional voice ID and notes.
No avatars yet.
