Manages Identity and Access Management (IAM) policies.
Any implementation of an API that offers access control features
implements the google.iam.v1.IAMPolicy interface.
Access control is applied when a principal (user or service account), takes
some action on a resource exposed by a service. Resources, identified by
URI-like names, are the unit of access control specification. Service
implementations can choose the granularity of access control and the
supported permissions for their resources.
For example one database service may allow access control to be
specified only at the Table level, whereas another might allow access control
to also be specified at the Column level.
This is intentionally not a CRUD style API because access control policies
are created and deleted implicitly with the resources to which they are
