Requests use the HTTP X-Api-Key header to both authenticate and authorize operations. API tokens are provided to you after you paid a HeyGen subscription.

As a developer, you'll need a pro HeyGen account first. Login you account and pay a pro subscription, then click the Account button at the left bottom, the API token shows there.


You can activate a trial token for testing on your account page. See below about how to activate your trial token:


Keep the API token secret and safe. Anyone with this API Key can use the HeyGen API as you. If it is compromised, please send an email to [email protected] and it can be deactivated or reset.
