It must be unique within one of the following scopes:\n\n- domain: A domain-scoped alias is visible to all users within the alias creator's domain and can be created only by a domain admin. A domain-scoped alias is often used when a course has an identifier external to Classroom.\n\n- project: A project-scoped alias is visible to any request from an application using the Developer Console project ID that created the alias and can be created by any project. A project-scoped alias is often used when an application has alternative identifiers. A random value can also be used to avoid duplicate courses in the event of transmission failures, as retrying a request will return `ALREADY_EXISTS` if a previous one has succeeded.\n\n| JSON representation |\n|-----------------------------|\n| ``` { \"alias\": string } ``` |\n\n| Fields ||\n|---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `alias` | `string` Alias string.
