You can rotate a webhook's secret on the Webhook Service page in Global Commerce if you think a webhook's secret is compromised. When you rotate the secret, Global Commerce blocks the old secret and generates a new one. You can choose to block the old secret immediately or allow it to expire after the specified expiration time when you rotate the secret. During that specified expiration time, both secrets work. It gives you time to make the transition from the old secret to the new secret. In either case, you can use the new secret immediately.
