## Actions defined by Amazon CloudWatch Observability Access Manager
<a name="list_oam-actions-as-permissions"></a>

You can specify the following actions in the `Action` element of an IAM policy statement. Use policies to grant permissions to perform an operation in Amazon. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions.
