### Method Details

`create(studentId, body=None, x__xgafv=None)`

    Creates a guardian invitation, and sends an email to the guardian asking
    them to confirm that they are the student's guardian.

    Once the guardian accepts the invitation, their `state` will change to
    `COMPLETED` and they will start receiving guardian notifications. A
    `Guardian` resource will also be created to represent the active guardian.

    The request object must have the `student_id` and
    `invited_email_address` fields set. Failing to set these fields, or
    setting any other fields in the request, will result in an error.

    This method returns the following error codes:

    * `PERMISSION_DENIED` if the current user does not have permission to
      manage guardians, if the guardian in question has already rejected
      too many requests for that student, if guardians are not enabled for the
      domain in question, or for other access errors.
    * `RESOURCE_EXHAUSTED` if the student or guardian has exceeded the guardian
      link limit.
    * `INVALID_ARGUMENT` if the guardian email address is not valid (for
      example, if it is too long), or if the format of the student ID provided
      cannot be recognized (it is not an email address, nor a `user_id` from
      this API). This error will also be returned if read-only fields are set,
      or if the `state` field is set to to a value other than `PENDING`.
    * `NOT_FOUND` if the student ID provided is a valid student ID, but
      Classroom has no record of that student.
    * `ALREADY_EXISTS` if there is already a pending guardian invitation for
      the student and `invited_email_address` provided, or if the provided
      `invited_email_address` matches the Google account of an existing
      `Guardian` for this user.

    Args:
      studentId: string, ID of the student (in standard format) (required)
      body: object, The request body.
        The object takes the form of:
