חובה. מסכה שמזהה אילו שדות בקובץ המצורף צריך לעדכן. העדכון נכשל אם צוינו שדות לא חוקיים. אם שדה תומך בערכים ריקים, אפשר לנקות אותו על ידי ציון שלו במסכת העדכון ולא באובייקט AddOnAttachment. אם שדה שלא תומך בערכי ריק נכלל במסיכת העדכון ולא מוגדר באובייקט AddOnAttachment, תוחזר שגיאת INVALID_ARGUMENT.
המורים יכולים לציין את השדות הבאים:
title
teacherViewUri
studentViewUri
studentWorkReviewUri
dueDate
dueTime
maxPoints
זוהי רשימה של שמות שדות מוגדרים במלואם, שמופרדים בפסיקים. דוגמה: "user.displayName,photo"
