# blockUnsubscribe

> Unsubscribe from block notifications.

Unsubscribe from block notifications.

## On ThorNode

The upstream node does not enable block subscriptions; subscribing returns `-32601 Method not found`. Use [Yellowstone gRPC](/api-reference/yellowstone/subscribe) or poll `getBlock`. There is nothing to unsubscribe.

## Parameters

<ParamField body="params" type="array" required>
  <Expandable title="properties" defaultOpen>
    <ParamField body="subscriptionId" type="integer" required>
      Subscription id to cancel.
    </ParamField>
  </Expandable>
</ParamField>

## Response

<ResponseField name="result" type="boolean">
  Unsubscribe success message.
</ResponseField>
