# signatureUnsubscribe

## signatureUnsubscribe WebSocket Method

> Unsubscribe from signature confirmation notification. This method cancels an existing signature subscription identified by the subscription ID that was returned from a previous signatureSubscribe call. Note that signature subscriptions are automatically cancelled by the server after sending the first notification, so this method is typically used to cancel a subscription before the transaction is confirmed or processed.<br>
