In GA3(UA), when making a call to their API batchGet endpoint (https://analyticsreporting.googleapis.com/v4/reports:batchGet), in the response it returns a field containing the total of each metric requested so you don't have to iterate through each row.
I am trying to do the same for GA4 but it doesn't return the total field. Has anyone figured this out before? I checked around and a similar question has popped up but it was language specific, so I couldn't apply it. I am creating the request via Postman.
I have tried looking at the GA4 documentation and in the response object(https://developers.google.com/analytics/devguides/reporting/data/v1/rest/v1beta/RunReportResponse), it has the totals field and states returned if requested but it does not state how to request this.
Looks like you need to add TOTAL the metricAggregations list in your request, see : https://developers.google.com/analytics/devguides/reporting/data/v1/rest/v1beta/properties/runReport#:~:text=see%20Pagination.-,metricAggregations,-%5B%5D
