In the Reporting API, you can retrieve performance data (metrics) for your account.
The following sample query retrieves the
all products in your account during a specific 30-day period:
SELECT metrics.impressions, metrics.clicks, metrics.ctr FROM MerchantPerformanceView WHERE segments.date BETWEEN '2020-12-01' AND '2020-12-30'
You can also segment the metrics in the query for more granular performance reports.
