Google Ads Offline Conversion Imports Ending – Migrate to Data Manager API
Migrate offline conversion imports to the Data Manager API before June 15 to avoid data loss.
Migrate all offline conversion import workflows to the Data Manager API before June 15.
Summary
Google announced that offline conversion imports using the UploadClickConversions request will stop working after June 15 for accounts that have not used the functionality in the last 180 days. The change affects offline conversion imports and enhanced conversions for leads, while other Google Ads API operations continue normally. To avoid disruptions in reporting, attribution, and automated bidding, developers must migrate these workflows to the Data Manager API, which offers a unified ingestion system for sending advertiser data into Google Ads. The update reflects Google’s push toward centralized, AI‑driven data infrastructure tied to first‑party data and automation. Failure to migrate before the deadline could result in conversion data loss and degraded campaign performance. The Data Manager API also provides a better developer experience and additional functionality not available in the existing workflow.
