Since sampling is not manageable via the API, it is also possible that there may be discrepancies between the API re-import and what you see in the Google Analytics 4 interface.
When connecting the connector, a security error is provided by Google; please disregard it.
In order to set up data re-import you must activate the Google Analytics data re-import connector by connecting your property ( propertyId ) that you wish to re-import and Eulerian.
Once the connector is created, you can define the data resynchronization period by initiating a synchronization process on the dates you wish to specify. To ensure a relevant level of performance and access for everyone, the time range for synchronization is limited.
Once activated, the connector will continuously attempt to synchronize the previous day's data until it is completely deactivated. It is not possible to delete data that has already been synchronized.
Data discrepancy
We have noticed that there may be discrepancies between the data re-imported via the API and what is visible in the Google Analytics 4 interface; unfortunately, we cannot make corrections at this level as we are dependent on the API functionalities.
