# 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>

<Note>
  The instance ID is the unique identifier for the deployment of the system and is included in every API call.
  Together with the environment (sandbox or production) it is used to connect to the right APIs, as well as dashboard.
</Note>

After completion, your transactions should appear in production environment.
