 <h3>Method Details</h3>
 <div class="method">
-    <code class="details" id="create">create(courseId, body, x__xgafv=None)</code>
-  <pre>Creates an alias for a course. This method returns the following error codes: * `PERMISSION_DENIED` if the requesting user is not permitted to create the alias or for access errors. * `NOT_FOUND` if the course does not exist. * `ALREADY_EXISTS` if the alias already exists.
+    <code class="details" id="create">create(courseId=None, body, x__xgafv=None)</code>
+  <pre>Creates an alias for a course.
+
+This method returns the following error codes:
+
+* `PERMISSION_DENIED` if the requesting user is not permitted to create the
+alias or for access errors.
+* `NOT_FOUND` if the course does not exist.
+* `ALREADY_EXISTS` if the alias already exists.
+* `FAILED_PRECONDITION` if the alias requested does not make sense for the
+  requesting user or course (for example, if a user not in a domain
+  attempts to access a domain-scoped alias).
 
 Args:
-  courseId: string, Identifier of the course to alias. This identifier can be either the Classroom-assigned identifier or an alias. (required)
+  courseId: string, Identifier of the course to alias.
+This identifier can be either the Classroom-assigned identifier or an
+alias. (required)
   body: object, The request body. (required)
     The object takes the form of:
 
-{ # Alternative identifier for a course. An alias uniquely identifies a course. It must be unique within one of the following scopes: * 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. * 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.
-    "alias": "A String", # Alias string. The format of the string indicates the desired alias scoping. * `d:` indicates a domain-scoped alias. Example: `d:math_101` * `p:` indicates a project-scoped alias. Example: `p:abc123` This field has a maximum length of 256 characters.
