Google Ads API v25.1 exposes metrics.original_conversion_value
The unadjusted conversion value — before value rules and new-customer bonuses — is queryable as metrics.original_conversion_value. In the UI it is the 'Original conv. value' column added in November 2025; Google: 'The same adjusted value that is determined at bidding time will be used for reporting.'
Source: Google Ads API release notes.
What it breaks
'Conv. value' and every ROAS built on it carry the value-rule multipliers inside them; finance reads a bidding instruction as revenue.
Who it hits: Accounts with conversion value rules or lifecycle (new-customer) goals; anyone reporting ROAS to finance.
The fix
Report to finance on original value, bid on adjusted value, and track the gap between the two columns as its own metric.
