Google Ads Data Manager API Replaces Legacy Conversion Imports by June 2026
Google launched the Data Manager API on December 9 2025 as a unified first-party data ingestion layer across Google Ads, GA4, and DV360. Starting June 15 2026, the Google Ads API will reject new offline conversion imports from developer tokens without recent activity. WooCommerce stores using plugin-based Enhanced Conversions face a forced migration. The Enhanced Conversions unified toggle coming in June 2026 adds urgency, as auto-migration only works for accounts that previously accepted Google’s customer data terms — a condition 67% of WooCommerce plugin setups fail.
