Retrieving metrics

The ability to retrieve metrics is at the heart of Calibre’s API. In this guide we’ll demonstrate how to fetch metrics for your pages efficiently.

Timeseries metrics for a given Site

You can query up to 6 months of reporting data per request. Use from and to parameters to specify date ranges.

Required API Permission: Read Sites
