Using Google Analytics Reporting API v4 in Rails with Oauth2

analyticsreportingv4.rb

# This summary shows how to set up a basic request to Google's Analytics Reporting API v4 from a Rails app.

# Gemfile
gem 'google-api-client', # v. 0.11
gem 'omniauth-google-oauth2' # v. 0.4.1 with Devise

# In a model or controller somewhere...
analytics = Google::Apis::AnalyticsreportingV4::AnalyticsReportingService.new
analytics.authorization = current_user.token # See: https://github.com/zquestz/omniauth-google-oauth2

date_range = Google::Apis::AnalyticsreportingV4::DateRange.new(start_date: '7DaysAgo', end_date: 'today')
metric = Google::Apis::AnalyticsreportingV4::Metric.new(expression: 'ga:sessions', alias: 'sessions')
dimension = Google::Apis::AnalyticsreportingV4::Dimension.new(name: 'ga:browser')

request = Google::Apis::AnalyticsreportingV4::GetReportsRequest.new(
  report_requests: [Google::Apis::AnalyticsreportingV4::ReportRequest.new(
    view_id: 'VIEW_ID_FROM_ANALYTICS_PROPERTY',
     metrics: [metric],
     dimensions: [dimension],
     date_ranges: [date_range]
  )]
) # thanks to @9mm: https://github.com/google/google-api-ruby-client/issues/489

response = analytics.batch_get_reports(request)
response.reports

@maurymmarques you should also require the v3 to look for management info, like listing accounts, properties and views. V4 is solely focused on providing a reporting API for the moment.

filters can be simplified like this:

request = Google::Apis::AnalyticsreportingV4::GetReportsRequest.new(
  report_requests: [Google::Apis::AnalyticsreportingV4::ReportRequest.new(
    view_id: view_id,
    metrics: [metric],
    dimensions: [dimension1, dimension2],
    date_ranges: [date_range],
    filters_expression: filters
  )]
)

note filters_expression: filters

Where filters variable is in the form of ga:medium==cpc,ga:medium==organic;ga:source==bing,ga:source==google

Where commas (,) mean OR and simicolons (;) mean AND (where OR takes precedence over AND

you can check the query explorer to play around with filters.

Here is filters documentation

Hi, sir
I'm unable to authorize the reporting API because I have a rake task that everyday runs and collects data but in the rake, task authorization is required without a consent screen and I have not added omniauth gem but with google-api-client gem I have to make request to reporting API. why does authorization fail?
