 The following environment variables are available for configuring the service:
 
-| Name | Description | Default |

-| `ENDPOINTS_CATALOG` | The endpoint of the catalog API. If set to `false` uses a mock implementation | `false` |

-| `ENDPOINTS_CHECKOUT` | The endpoint of the checkout API. If set to `false` uses a mock implementation | `false` |
-| `ENDPOINTS_ASSETS` | The endpoint of the assets service. If set to `false` uses a mock implementation | `false` |
-| `ENDPOINTS_HTTP_KEEPALIVE` | Set to false to disable HTTP keepalive on requests to backend services | `true` |
