# Reporting tasks

> Per-operation reference for the buyer reporting API

Each page below documents a single reporting operation — request, parameters, response shape, and errors. Use `/reporting/metrics` for day-grain delivery rollups across the advertiser → campaign → media buy → package tree, and the events summary for hour-grain counts from your own event sources. For the conceptual model, see the [Reporting overview guide](/v2/guides/reporting-overview).
