AuditConfig
Specifies the audit configuration for a service. The configuration determines which permission types are logged, and what identities, if any, are exempted from logging. An AuditConfig must have one or more AuditLogConfigs.
If there are AuditConfigs for both allServices 
and a specific service,
the union of the two AuditConfigs is used for that service: the log_types
specified in each AuditConfig are enabled, and the exempted_members in each
AuditLogConfig are exempted.
Example Policy with multiple AuditConfigs:
 {
  "audit_configs": [
    {
      "service": "allServices",
      "audit_log_configs": [
        {
          "log_type": "DATA_READ",
          "exempted_members": [
            "user:jose@example.com"
          ]
        },
        {
          "log_type": "DATA_WRITE"
        },
        {
          "log_type": "ADMIN_READ"
        }
      ]
    },
    {
      "service": "sampleservice.googleapis.com",
      "audit_log_configs": [
        {
          "log_type": "DATA_READ"
        },
        {
          "log_type": "DATA_WRITE",
          "exempted_members": [
            "user:aliya@example.com"
          ]
        }
      ]
    }
  ]
} 
 
For sampleservice, this policy enables DATA_READ, DATA_WRITE and ADMIN_READ
logging. It also exempts jose@example.com 
from DATA_READ logging, and aliya@example.com 
from DATA_WRITE logging.
AuditConfigDelta
One delta entry for AuditConfig. Each individual change (only one exempted_member in each entry) to a AuditConfig will be a separate entry.
AuditConfigDelta.Types
Container for nested types declared in the AuditConfigDelta message type.
AuditLogConfig
Provides the configuration for logging a type of permissions. Example:
 {
  "audit_log_configs": [
    {
      "log_type": "DATA_READ",
      "exempted_members": [
        "user:jose@example.com"
      ]
    },
    {
      "log_type": "DATA_WRITE"
    }
  ]
} 
 
This enables 'DATA_READ' and 'DATA_WRITE' logging, while exempting jose@example.com from DATA_READ logging.
AuditLogConfig.Types
Container for nested types declared in the AuditLogConfig message type.
Binding
Associates members 
, or principals, with a role 
.
BindingDelta
One delta entry for Binding. Each individual change (only one member in each entry) to a binding will be a separate entry.
BindingDelta.Types
Container for nested types declared in the BindingDelta message type.
GetIamPolicyRequest
Request message for GetIamPolicy 
method.
GetPolicyOptions
Encapsulates settings provided to GetIamPolicy.
IAMPolicy
API Overview
Manages Identity and Access Management (IAM) policies.
Any implementation of an API that offers access control features implements the google.iam.v1.IAMPolicy interface.
Data model
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.
Policy Structure
See google.iam.v1.Policy
This is intentionally not a CRUD style API because access control policies are created and deleted implicitly with the resources to which they are attached.
IAMPolicy.IAMPolicyBase
Base class for server-side implementations of IAMPolicy
IAMPolicy.IAMPolicyClient
Client for IAMPolicy
IAMPolicyClient
IAMPolicy client wrapper, for convenient use.
IAMPolicyClientBuilder
Builder class for IAMPolicyClient to provide simple configuration of credentials, endpoint etc.
IAMPolicyClientImpl
IAMPolicy client wrapper implementation, for convenient use.
IAMPolicySettings
Settings for IAMPolicyClient instances.
Policy
An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources.
A Policy 
is a collection of bindings 
. A binding 
binds one or more members 
, or principals, to a single role 
. Principals can be user
accounts, service accounts, Google groups, and domains (such as G Suite). A role 
is a named list of permissions; each role 
can be an IAM predefined
role or a user-created custom role.
For some types of Google Cloud resources, a binding 
can also specify a condition 
, which is a logical expression that allows access to a resource
only if the expression evaluates to true 
. A condition can add constraints
based on attributes of the request, the resource, or both. To learn which
resources support conditions in their IAM policies, see the IAM
documentation 
.

      role: roles/resourcemanager.organizationAdmin
    - members:
      - user:eve@example.com
      role: roles/resourcemanager.organizationViewer
      condition:
        title: expirable access
        description: Does not grant access after Sep 2020
        expression: request.time < timestamp('2020-10-01T00:00:00.000Z')
