# → Business Settings → Accounts → Pages
# → Har page pe click karo
# → "Add People" → System User select karo → Role: ADMIN
# → Save karo
# → Yeh 10+ pages ke liye ek ek karke karna hoga

# STEP 5: Token verify karo (browser mein yeh URL kholo)
# https://graph.facebook.com/v19.0/me?access_token=TUMHARA_TOKEN_YAHAN
# Response mein "id" aur "name" aana chahiye → Token sahi hai!
