Controlling Access in the Admin API

The Google App Engine Admin API uses Google Cloud Identity and Access Management (IAM) for access control.

Access control in Google App Engine Admin API can be configured at the project level. Access to Google Cloud projects and the resources within them can be granted to user accounts, domains, groups, or service accounts. For example:

• Grant access to all the resources within a project to an individual member or to all the members of a service account.
• Grant access on a per-role basis, rather than for the whole project so that project members are provided limited capabilities. For example, read-only access to resources, or ability to deploy new versions, but not configure traffic to those versions.

For a detailed description of IAM and its features, see the Google Cloud Identity and Access Management documentation.

Every Admin API method requires the caller to have the necessary permissions. See the following section for a list of all the permissions and roles that the Admin API IAM supports.

Permissions and roles

This section summarizes the permissions and roles that Admin API IAM supports.

For details about the App Engine roles, see App Engine Access Control.

Note that the roles roles/owner, roles/editor, and roles/viewer include permissions for other Google Cloud services as well. For more information about these primitive roles, see Access Control.

Permissions not available for custom roles

If you want to configure access beyond the predefined IAM roles, you can create a custom role. However, the following permissions are not available for custom roles:

• appengine.applications.disable
• appengine.applications.list
• appengine.instances.update
• appengine.operations.cancel
• appengine.operations.delete
• appengine.services.create

These permissions are not needed for any operations.

Controlling access via the Cloud Console

You can use the Cloud Console to manage access control for your Google Cloud projects.

Setting project-wide access controls

To grant members access to a Google Cloud project and its resources, see Granting, Changing, and Revoking Access to Project Members.

Setting service account access controls

You can create a service account in a Google Cloud project to grant your app programmatic access to Google Cloud services. For example, use a service account to allow one Google Cloud project to send HTTP request with the Google App Engine Admin API to another Google Cloud project.

To create service accounts and grant access, see the following IAM topics:

• Creating and Managing Service Accounts
• Granting Roles to Service Accounts
