# Going live

After testing your implementation in your sandbox environment, the next step
is to set up your production environment and go live.

1. Change the `environment` parameter to `production`.
2. Create a production API key

<CodeGroup>
  ```html React theme={"system"}
  <form action='/' id='payment-form'>
    <Embed
      gr4vyId='example'
      environment='production',
      ...
    />
    <input type="submit" />
  </form>
  ```

  ```js Node theme={"system"}
  setup({
    gr4vyId: "example",
    environment: "production"
    ...
  });
  ```

  ```js CDN theme={"system"}
  gr4vy.setup({
    gr4vyId: "example",
    environment "production",
    ...
  });
  ```
</CodeGroup>

After completion, your transactions should appear in production environment.
