Google Ads Conversions

From February 2, 2026, the Google Ads API stopped accepting new implementations of session attribute and IP address data in conversion imports. From June 15, offline conversion imports were blocked for new adopters entirely. Enhanced conversions for web and leads merged into a single toggle in June 2026. The migration path is the Data Manager API, launched December 2025. WooCommerce stores that built custom conversion pipelines through the Ads API now face a cascade of cutoffs pushing all data ingestion to a unified server-side infrastructure.

Google disabled Customer Match uploads through the Google Ads API on April 1, 2026, cutting off any developer token inactive for 180+ days. WooCommerce stores relying on OfflineUserDataJobService or UserDataService for audience list uploads now receive CUSTOMER_NOT_ALLOWLISTED errors. The mandatory migration path is Google’s Data Manager API, a unified first-party data ingestion layer launched December 2025 that replaces five separate data workflows with a single endpoint. Stores using BigQuery’s native connector or manual CSV uploads in Audience Manager are unaffected.

Google launched the Data Manager API on December 9, 2025, replacing five separate data pipelines — Customer Match, offline conversions, Enhanced Conversions for leads, store sales, and mobile device identifiers — with a single endpoint that works across Google Ads, GA4, and DV360. Customer Match via the legacy Google Ads API was disabled on April 1, 2026, and the Enhanced Conversions unified toggle removes method selection from the Google Ads interface in June 2026. WooCommerce stores using plugin-based Enhanced Conversions face a forced migration.

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.

Starting June 15 2026, the Google Ads API will reject UploadClickConversions requests from any developer token that hasn’t imported offline conversions between December 2025 and May 2026. WooCommerce stores and tracking plugins that built custom integrations against this endpoint must migrate to the Data Manager API — Google’s unified first-party data ingestion layer launched December 9 2025 with eleven partners. Stores already importing conversions get a transition window; new implementations are blocked entirely after the deadline.

67% of Enhanced Conversions setups fail on first implementation. That’s not a typo. If you’ve spent hours configuring GTM tags, wrestling with data layer variables, and wondering why Google Ads still shows zero enhanced conversions—you’re in the majority, not the minority. The problem isn’t you. Enhanced Conversions for WooCommerce requires perfect coordination of three moving … Read more
