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.
| GetIamPolicy |
|---|
|
Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.
|
| SetIamPolicy |
|---|
|
Sets the access control policy on the specified resource. Replaces any existing policy. Can return
|
| TestIamPermissions |
|---|
|
Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Binding
Associates members, or principals, with a role.
| Fields | |
|---|---|
role |
Role that is assigned to the list of For an overview of the IAM roles and permissions, see the IAM documentation. For a list of the available pre-defined roles, see here. |
members[] |
Specifies the principals requesting access for a Google Cloud resource.
|
condition |
The condition that is associated with this binding. If the condition evaluates to If the condition evaluates to To learn which resources support conditions in their IAM policies, see the IAM documentation. |
GetIamPolicyRequest
Request message for GetIamPolicy method.
| Fields | |
|---|---|
resource |
REQUIRED: The resource for which the policy is being requested. See Resource names for the appropriate value for this field. |
options |
OPTIONAL: A |
GetPolicyOptions
Encapsulates settings provided to GetIamPolicy.
| Fields | |
|---|---|
requested_ |
Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1. To learn which resources support conditions in their IAM policies, see the IAM documentation. |
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.
