        This method provides a clean way to close WebSocket connections while preserving active orders when [**Cancel On Disconnect (COD)**](https://docs.deribit.com/api-reference/session-management/private-enable_cancel_on_disconnect) is enabled.


        **Use Cases:**


        - **Clean Shutdown:** Properly close WebSocket connections during application shutdown or restart

        - **Order Preservation:** Close connections without triggering order cancellations when COD is enabled

        - **Session Management:** Invalidate tokens to ensure security when closing connections

        - **Maintenance Operations:** Temporarily disconnect for system maintenance without affecting trading positions


        **Cancel On Disconnect (COD) Behavior:**


        When Cancel On Disconnect is enabled for your connection, this method provides a safe way to close the connection without triggering automatic order cancellations. This is different from other disconnection scenarios:


        - **Graceful logout** (this method): Orders are **NOT cancelled**, even if COD is enabled

        - **Unexpected disconnection:** Orders are **cancelled** if COD is enabled

        - **Inactivity timeout:** Orders are **cancelled** if COD is enabled

        - **Heartbeat failure:** Orders are **cancelled** if COD is enabled


        This distinction allows you to perform planned disconnections (e.g., for maintenance, updates, or reconnection) while preserving your active orders.


        **WebSocket Only:**


        This method is designed exclusively for WebSocket connections. Attempting to use it via REST/HTTP will result in a 400 error response.


        **Note:** This method has no response. The WebSocket connection is closed immediately after the request is processed.

        When heartbeats have been set up, the API server will send `heartbeat` messages and `test_request` messages. Your software should respond to `test_request` messages by sending a `/api/v2/public/test` request. If your software fails to do so, the API server will immediately close the connection. If your account is configured to cancel on disconnect, any orders opened over the connection will be cancelled.
