  <Step title="Create a Lumx account">
    Sign up at the [Dashboard](https://dashboard.lumx.io). From there you can manage projects, generate API keys, and monitor transaction activity.

    <Info>
      New accounts start with a Sandbox environment for testing. To access Production, [schedule a call with our team](https://cal.com/caiobrbs/discovery).

  <Step title="Generate your API key">
    Navigate to **Developers → API Keys** and create a new key for your project.

    Copy your API key immediately. It's only shown once. If compromised, revoke and rotate from the Dashboard.

    <Danger>
      Store your API keys securely. Never commit them to version control or expose them in client-side code.
