Description

🚨 **IF THIS TOOL RETURNS A QUOTA ERROR:** - The error message will include a clickable upgrade link - Show the FULL error message to the user (it contains the upgrade link) - DO NOT attempt to work around the error or use alternative data - DO NOT create campaigns or perform actions without valid tool data - STOP and direct the user to upgrade via the provided link Set device bid modifiers on an AD GROUP — bid up/down per device, finer than the campaign level. Adjusts (or creates) MOBILE/TABLET/DESKTOP bid modifiers on ONE ad group. Update-or- create: existing device bids are updated, missing ones are created. Idempotent on re-set. **Each entry:** - device: MOBILE | TABLET | DESKTOP - bid_modifier: 1.2 = +20%, 0.8 = -20%, 1.0 = no change **Required:** ad_group_id + 1+ devices. Note: DemandGen ad groups use smart bidding and don't support device bid modifiers (guarded cleanly). CONNECTED_TV/OTHER are campaign-level only.
