# Webhook signatures for subaccounts

> Share your workspace's webhook secret key so subaccounts sign their webhooks too.

![Webhook signature settings with the option to share the secret key with subaccounts](https://storage.googleapis.com/granular-changelog/doc-images/changelog_webhook_signature_subaccounts.png)

Subaccount webhooks went out unsigned, so you couldn't confirm they came from Synthflow. You can now [share your workspace's secret key with your subaccounts](/security#subaccounts), so their webhooks carry the same `HTTP_SYNTHFLOW_SIGNATURE` header you already validate.
