## Callback Response

You receive asynchronous HTTP callback response notifications when subscribed account link events occur. These notifications are sent to the callback URL you provide during the onboarding process. 

> You can configure which events to receive. For Merchant Services, refer to the [Notifications](/api/commerce/optimization-protection/notifications/notifications) API. For Treasury Services, contact your relationship manager.
