# slotUnsubscribe

## slotUnsubscribe WebSocket Method

> Unsubscribe from slot notifications. This method cancels an existing slot subscription identified by the subscription ID that was returned from a previous slotSubscribe call. Once unsubscribed, you will no longer receive slotNotification messages when new slots are processed by the validator. This is useful for stopping high-frequency slot monitoring when no longer needed.<br>
