מסכה שמזהה אילו שדות במודעה צריך לעדכן. השדה הזה נדרש כדי לבצע עדכון. העדכון נכשל אם צוינו שדות לא חוקיים. אם שדה תומך בערכים ריקים, אפשר לנקות אותו על ידי ציון השדה במסיכת העדכון ולא באובייקט ההודעה. אם שדה שלא תומך בערכים ריקים נכלל במסכת העדכון ולא מוגדר באובייקט ההודעה, תוחזר שגיאה מסוג INVALID_ARGUMENT.
המורים יכולים לציין את השדות הבאים:
text
state
scheduledTime
זוהי רשימה של שמות שדות מוגדרים במלואם, שמופרדים בפסיקים. דוגמה: "user.displayName,photo"
