Google Data Manager API Is the New Default for First-Party Data

Google launched the Data Manager API as a single centralized integration for audiences and conversion events, positioned as the new default for first-party data activation (CustomerLabs, 2026). Data Manager API limits each project to 100,000 requests/day and 300 requests/minute (PPC Land, 2026). Individual requests can contain up to 2,000 conversion events with up to 10 user identifiers each (PPC Land, 2026).

Google Merged Enhanced Conversions Into One Toggle — What Broke on WooCommerce

In June 2026, Google merged Enhanced Conversions for Web and Enhanced Conversions for Leads into a single on/off toggle, while simultaneously blocking offline conversion imports via the Google Ads API in favor of the Data Manager API. Google says no action is required — but that’s only true if your existing setup was already correct. 67% of first-implementation Enhanced Conversions setups on WooCommerce fail audit due to data layer timing issues, meaning a majority of auto-migrated accounts carried broken attribution into the unified system without noticing.

Google Ads Closed the API Door on IP and Session Data

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 Killed Customer Match Uploads in the Ads API on April 1

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 Data Manager API Replaces Five Pipelines With One Endpoint

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 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.

Google Ads API Blocks New Offline Conversion Imports June 15

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.
