GA4 now includes a Report Identity API (Alpha, via the Admin API).
It lets you check which report identity is being used in a GA4 property:
– BLENDED
– OBSERVED
– DEVICE_BASED
– IDENTITY_BLENDING_STRATEGY_UNSPECIFIED (if not defined)
This makes it easier to automate audits and validate GA4 configurations without manually checking each property.
