Google Cloud offers Identity and Access Management (IAM), which lets you give more granular access to specific Google Cloud resources and prevents unwanted access to other resources. IAM lets you adopt the security principle of least privilege, so you grant only the necessary access to your resources.
IAM lets you control who (users) has what access (roles) to which resources by setting IAM policies. IAM policies grant specific roles to a user giving the user certain permissions.
This page explains the Identity and Access Management roles that are available for the Cloud Billing APIs. For example, you can use IAM to grant roles such as Admin, User, and Project Manager for a Cloud Billing account. For a detailed description of IAM and its features, see the Identity and Access Management developer's guide. In particular, see its Granting, Changing, and Revoking Access section.
Permissions and Roles
For a user to view Cloud Billing account details in the Google Cloud console, or for a Cloud Billing API method to return Cloud Billing account information, the user or caller must have the necessary permissions. The following table list the IAM permissions and roles needed to use the Cloud Billing Budget API.
Required permissions for the Cloud Billing Budget API
The following table outlines which permissions are necessary to call each Cloud Billing Budget API method. Also included are the standard IAM Billing roles that automatically grant those permissions.
| API Method | Required Permission | IAM Role that grants permissions |

For single-project budgets, instead of billing account permissions, the
caller can have the following permissions on the project:
|
Billing Account Administrator, Billing Account Costs Manager, or Billing Account Viewer on the budget's Cloud Billing account. For single-project budgets, Project Owner, Project Editor, or Project Viewer on the project. |

Roles
You don't directly give users permissions; instead, you grant them roles, which have one or more permissions bundled within them.
You can grant one or more roles on the same resource.
The following table lists the standard IAM Billing roles that you can grant to access the Cloud Billing APIs, the description of what the role does, and the permissions bundled within that role.
| Role | Permissions |
|---|---|
Billing Account Administrator( Provides access to see and manage all aspects of billing accounts. Lowest-level resources where you can grant this role:
