# Rotate Signing Secret

> Generate a new signing secret for a webhook.

> [!NOTE]
>
> For 24 hours after the rotation, payloads are signed with both the new and the
> previous secret, so either one verifies them. After that, only the new secret
> does. Use that window to update the secret your application uses to [verify
> requests](/docs/webhooks/verify-webhooks-requests) without dropping events.

## Path Parameters

The Webhook ID.

## Response Fields
