Additional Features

Every API exposure, API subscription, event exposure, and event subscription works out of the box with a sensible default configuration. However, you can customize behavior by adding additional features to your Rover file. These features let you fine-tune traffic management, secure communication between services, filter events, and more.

tip

All features on this page are optional. You only need to configure them if the default behavior does not meet your requirements.

How to Use Additional Features

exposures:
  - type: api
    basePath: /checkout/v1
    upstream: https://checkout.internal:8080
    approval: SIMPLE
    visibility: ENTERPRISE
    # Additional feature:
    rateLimit:
      provider:
        second: 100
