Method: projects.serviceAccounts.setIamPolicy

Sets the Cloud IAM access control policy for a ServiceAccount.

Note: Service accounts are both resources and identities. This method treats the service account as a resource. Use it to grant members access to the service account, such as when they need to impersonate it.

This method does not grant the service account access to other resources, such as projects. To grant a service account access to resources, include the service account in the Cloud IAM policy for the desired resource, then call the appropriate setIamPolicy method on the target resource. For example, to grant a service account access to a project, call the projects.setIamPolicy method.
