Google has officially added programmatic access to GA4 reporting identity settings via the Admin API. This update introduces the updateReportingIdentitySettings endpoint. While it sounds highly technical, it solves one of the biggest headaches for data engineers and agencies managing automated reporting pipelines.
If you extract Google Analytics 4 data via the GA4 Data API to power Looker Studio dashboards or custom reporting tools, you already know the pain of data thresholding. Here is exactly what this new API endpoint does, why agencies heavily requested it, and how analysts can use similar concepts to fix data sampling directly inside the UI.
Why Agencies Demanded Programmatic Access
To understand the value of this update, you have to understand GA4 data thresholding. When properties use the "Blended" or "Observed" reporting identity, Google Analytics applies strict thresholds to hide rows of data and protect user privacy (typically when User-ID tracking or behavioral modeling is active).
This creates major issues for automated reporting. While the native BigQuery export remains unaffected because it uses raw event data, any pipeline extracting aggregated metrics via the GA4 Data API is heavily thresholded. Your client dashboards suddenly display missing rows and lower-than-expected totals.
Historically, the only fix was entirely manual. An analyst had to log into the GA4 Admin panel, manually switch the reporting identity to "Device-based" (which removes the privacy thresholds), wait for the automated Data API extraction to finish, and switch it back to "Blended". For agencies managing hundreds of client properties, this manual process was highly inefficient.
How the New GA4 Admin API Endpoint Works
The new REST endpoint allows developers to automate this exact toggle. By sending a PATCH request to https://analyticsadmin.googleapis.com/v1alpha/properties/*/reportingIdentitySettings, your scripts can now control how GA4 resolves user identities on the fly.
You can program your API extraction scripts to dynamically set the property to "Device-based" right before executing a query, then immediately revert it back to its original state. This ensures your external dashboards always display un-thresholded, accurate aggregated data.
Note that the endpoint requires the https://www.googleapis.com/auth/analytics.edit OAuth scope. Your service account or authenticated user must have Editor or Administrator permissions on the property to successfully change the setting.
Fixing Data Thresholds for Analysts in the GA4 UI
The new API endpoint is an incredible tool for data engineers building automated pipelines. However, it does not help standard analysts who spend their days reviewing data directly inside the Google Analytics interface.
If you are an analyst fighting data thresholds and sampling limits inside GA4 Explorations, you still have to fight the user interface. Instead of dealing with abbreviated numbers and hidden rows, you can install the free GA4 Optimizer Chrome extension.
The extension bypasses common UI limitations to give you direct access to the data you actually need:
- Detailed Results Shortcut: When your Exploration triggers a sampling warning, pressing
Ctrl+Shift+Qinstantly forces GA4 to use "More detailed results," reducing aggressive sampling and returning a more accurate dataset. - Exact Numbers on Hover: GA4 heavily abbreviates metrics on the Home screen (like showing "24K" instead of "24,390"). Hovering over these metrics with the extension active reveals the exact un-abbreviated API response natively.
- Increase Row Limits: Native GA4 Standard Reports cap out at 250 rows, forcing you to constantly paginate to see your full data set. The extension injects a 500 rows per page option directly into the native UI dropdown.
Whether you are a developer using the new updateReportingIdentitySettings API to clean up your dashboard feeds, or an analyst using browser extensions to clean up your UI, getting accurate data out of GA4 is finally becoming easier.

Frequently Asked Questions
What is the GA4 updateReportingIdentitySettings API endpoint?
The updateReportingIdentitySettings endpoint is a new feature in the GA4 Admin API. It allows developers to programmatically change a property's reporting identity between Blended, Observed, and Device-based without using the manual Google Analytics admin interface.
Why did Google add programmatic access to the GA4 Reporting Identity?
Google added this endpoint based on high demand from agencies and data engineers. Automated reporting pipelines often pull thresholded data when properties are set to Blended identity. This API allows scripts to automatically toggle the identity to Device-based, extract raw data, and toggle it back.
Can standard analysts use the GA4 API to change reporting identity?
No. The updateReportingIdentitySettings endpoint requires the analytics.edit authorization scope. Only users or service accounts with Editor or Administrator access can successfully execute this API request. Lower-level roles remain restricted.
