There are four new CloudWatch Dashboards APIs: PutDashboard, GetDashboard, DeleteDashboards, and ListDashboards. PutDashboard is used to create a new dashboard or modify an existing one whereas GetDashboard is the API to get the details of a specific dashboard. ListDashboards and DeleteDashboards are used to get the names or delete multiple dashboards, respectively. The APIs can be accessed through AWS SDK or through CLI tools.
