# Delete Webhook

> Permanently delete a webhook subscription.

Permanently deletes a webhook subscription. This action cannot be undone.

<Warning>
  Deleting a webhook is permanent. If you only need to temporarily stop receiving events, consider using the [Update Webhook](/evm/subscriptions/update-webhook) endpoint to set `active: false` instead.
</Warning>

After deletion:

* No new webhook deliveries will be sent
* The webhook ID becomes invalid
* All subscribed addresses are removed
* Historical delivery logs may still be visible in your dev portal
