The transition of session attribute and IP address data imports from the Google Ads API to the Data Manager API marks a significant shift in how advertisers track and measure conversions. This migration ensures enhanced data management capabilities and aligns with Google’s evolving infrastructure for richer attribution insights.
Understanding the Change: Why Google Is Moving Conversion Data
As Google Ads continues to evolve, the emphasis on comprehensive and accurate conversion tracking gains prominence. Historically, the Ads API allowed developers to import session-level attributes and IP address data directly into conversion records. However, starting February 2nd, new adopters will be blocked from sending such data via the Ads API. Existing users have temporary access but are encouraged to migrate to the Data Manager API.
This strategic shift consolidates complex data ingestion into a single, optimized interface. The Data Manager API is designed to handle intricate user-level signals, offering advertisers improved data fidelity and a unified platform for conversion management.
“Centralizing session and IP data imports within the Data Manager API reduces processing fragmentation and enhances data quality for smarter attribution models,” said Laura Chen, a digital marketing analyst specializing in API integrations.
Implications for Advertisers and Developers
For advertisers relying on conversion imports enriched with session attributes and IP signals, this change can directly impact measurement and automated bidding strategies. Without timely migration, conversion data may be rejected, leading to incomplete reports and potentially skewed campaign optimization.
The primary error developers may encounter post-migration is CUSTOMER_NOT_ALLOWLISTED_FOR_THIS_FEATURE, indicating the Ads API refusing conversion records containing session or IP data. This partial-failure response signals the necessity to transition the data import workflows.
Migrating Data Imports: Best Practices
Developers should first sanitize their current import processes by removing session attribute and IP address data from Ads API conversion submissions. Parallel development efforts should focus on implementing Data Manager API integration, which is the designated endpoint for these complex data payloads.
Google’s official documentation outlines detailed migration steps, including authentication protocols, data formatting standards, and batch processing capabilities. Maintaining robust synchronization between the two APIs during the transition phase helps safeguard conversion continuity.
Benefits of Using the Data Manager API
Transitioning to the Data Manager API offers several advantages:
– Enhanced data ingestion capacity tailored for session-level granularity.
– Improved support for IP-based signals, contributing to more accurate attribution.
– Future-proofing measurement frameworks aligned with Google’s roadmap for privacy and automation.
– Streamlined developer experience with clearer API boundaries between campaign management and user-level data.
“The Data Manager API is a strategic tool to navigate evolving privacy standards while still capturing essential signals for attribution,” explained Marcus Lee, a programmatic advertising expert.
For example, advertisers running complex multi-channel campaigns can leverage the Data Manager API to feed granular user behavior data into Google’s measurement systems. This access allows for better audience segmentation and optimized bidding algorithms, driving higher ROI.
Transitional Considerations and Timeline
Although existing developers currently retain access to session attribute and IP data imports through the Ads API, continued reliance is unsustainable. Google enforces developer-token allowlisting, signaling a phased deprecation in favor of universal Data Manager API adoption.
Advertisers should proactively audit their conversion import pipelines, identify dependencies on session or IP data within the Ads API, and begin migration immediately to prevent disruptions. Testing the new Data Manager API setup in sandbox environments is advisable before full-scale deployment.
Potential Challenges and Mitigation Strategies
Some challenges during migration include data schema adjustments and learning curve for the Data Manager API’s interface. Collaborating with experienced API developers and utilizing Google’s support channels can facilitate a smoother transition.
Additionally, advertisers should monitor campaign performance closely after migration to identify any discrepancies caused by data discrepancies or synchronization issues.

Conclusion: Embracing the Future of Conversion Tracking
The deprecation of session attributes and IP address data imports via the Google Ads API emphasizes Google’s commitment to a more integrated and sophisticated measurement ecosystem. Migrating to the Data Manager API is no longer optional but a necessary step to ensure continued access to rich conversion data and advanced attribution capabilities.
As the digital advertising landscape grows more privacy-focused and data-driven, leveraging the right APIs will enable marketers to maintain an edge in campaign performance and measurement integrity.
“Adapting to this API migration is essential for marketers aiming to future-proof their conversion tracking strategies,” added Laura Chen.
