    headers: {
      Authorization: `Token ${process.env.REVUE_API_KEY}`
    }

};

Usage

First, create a Revue account.

From the Integrations page, retrieve your API key at the bottom.

To securely access the API, we need to include the secret with each request. We also do not want to commit secrets to git. Thus, we should use an environment variable. Learn how to add environment variables in Vercel.
