CreatePermission

The following Java sample shows how to use the CreatePermission operation.

The operation assigns access permissions from a private CA to a designated AWS service principal. Services can be given permission to create and retrieve certificates from a private CA, as well as list the active permissions that the private CA has granted. In order to automatically renew certificates through ACM, you must assign all possible permissions (IssueCertificate, GetCertificate, and ListPermissions) from the CA to the ACM service principal (acm.amazonaws.com). You can find a CA's ARN by calling the ListCertificateAuthorities function.

Once a permission is created, you can inspect it with the ListPermissions function or delete it with the DeletePermission function.
