Google Analytics Report API v4: get Sessions and Revenue data

Question

I trying to get Sessions, Revenue, Transactions, Bounce Rate data from Google Analytics Report API v4 with grouping by Chanel:

• Organic search
• Email
• Direct
• Branded Paid Search
• Social
• Referral
• .. etc

Right now I'm programming a Java module with test Request which has setted following parameters:

Dimensions:

ga:acquisitionTrafficChannel;

Metrics:

ga:sessions

ga:percentNewSessions

ga:newUsers

When I use ga:acquisitionTrafficChannel + ga:sessions GA Report api returns values, but when I try to add in request ga:percentNewSessions, ga:newUsers , it returns error:

{
  "domain": "global",
  "message": "Selected dimensions and metrics cannot be queried together.",
  "reason": "badRequest"
}

To perform request in code I do following:

DateRange dateRange = new DateRange();
            dateRange.setStartDate("2015-06-15");
            dateRange.setEndDate("2015-06-30");
            ReportRequest request = new ReportRequest()
                    .setViewId(context.getProperty(VIEW_ID).evaluateAttributeExpressions().getValue())
                    .setDateRanges(Arrays.asList(dateRange))
                    .setDimensions(Arrays.asList(
                            new Dimension().setName("ga:acquisitionTrafficChannel")
                    ))
                    .setMetrics(Arrays.asList(
                            new Metric().setExpression("ga:sessions"),
                            new Metric().setExpression("ga:percentNewSessions"),
                            new Metric().setExpression("ga:newUsers")
                    ));

            ArrayList<ReportRequest> requests = new ArrayList<>();
            requests.add(request);
            GetReportsRequest getReport = new GetReportsRequest().setReportRequests(requests);
            GetReportsResponse response = service.reports().batchGet(getReport).execute();

How to do request correctly? Is in the right direction do I go?

Because as I said, I will need to do same thing with Revenue, Bounce Rate.. but I not fully understand how to combine Metrics and Dimensions without errors.

Thanks for any help

Answer 1

About my question:

As solution for my needs I used following combination in code:

To get all Channel groups ("Organic Search, Email, Direct, etc") I used following dimension: ga:channelGrouping - it will return all

To get values for Sessions, Revenue, Transactions, Bounce Rate, etc I used following metrics:

ga:sessions
ga:transactionRevenue
ga:transactions
ga:bounceRate

Also here can be more metrics if it is needed.

Maybe it will be useful to somebody.

Actually, question about error with combination in question (with ga:acquisitionTrafficChannel ) is still open :)
