Do this with verapliJSON for agents

Steps

Steps marked “human step” are ones only you can do: verapli never signs in, submits, pays or accepts terms for you.

  1. Sign in or create a HeyGen account

    Sign in to HeyGen. If you have no account yet, you create it yourself; verapli does not create accounts.

    • Guided by hand
    • Human step: You sign in

    Where: https://app.heygen.com/

  2. Create an API key

    On the API keys page create a key and store it as HEYGEN_API_KEY (sent as X-Api-Key), or run stripe projects add heygen/api.

    • Guided by hand
    • Human step: You press submit
    • After: Sign in or create a HeyGen account

    verapli captures HEYGEN_API_KEY here by plain code: encrypted in your browser, never shown to AI.

    Where: https://platform.heygen.com/api-keys
