Starting April 1, 2026, Customer Match uploads through the Google Ads API will no longer work. Instead, users must switch to the Data Manager API for managing and uploading Customer Match data. This change affects developers who have not uploaded Customer Match data via the Google Ads API in the last 180 days; attempts to upload after this date using the Google Ads API will fail.
Key Changes
- Customer Match uploads via Google Ads API will stop working from April 1, 2026.
- The Data Manager API must be used for Customer Match data uploads and management.
- For other Google Ads API operations unrelated to Customer Match, the Google Ads API remains unchanged.
- Developers inactive in Customer Match uploads (no uploads in last 180 days) will encounter errors if they try to upload via the Google Ads API after the cutoff date.
Reasons for the Change
- The Data Manager API offers a unified data ingestion API across all Google platforms.
- It includes enhanced security protocols, such as confidential matching and encryption.
- Provides a better developer experience with new exclusive features.
- Google encourages developers to review the upgrade guide and blog post for detailed information on transitioning to the Data Manager API.
