Get reporting metrics

GET /api/v2/storefront/reporting/metrics Returns reporting metrics for every media buy the Merchandising Agent participates in through your storefront’s inventory sources. The storefront does not own these media buys — reporting is visible because the Merchandising Agent is the ADCP party to the transactions. The hierarchy is advertiser → media buy → package; there is no campaign level.

Request

curl

curl -G https://api.interchange.io/api/v2/storefront/reporting/metrics \
  -H "Authorization: Bearer $SCOPE3_API_KEY" \
  --data-urlencode "view=summary" \
  --data-urlencode "startDate=2026-01-01" \
  --data-urlencode "endDate=2026-01-31" \
  --data-urlencode "inventorySourceId=source_abc123"

Parameters

Field	Type	Required	Notes
`inventorySourceId`	string	No	Scope to one inventory source. Omit to include every source on the storefront
`startDate`	string	No	Start date, `YYYY-MM-DD`
`endDate`	string	No	End date, `YYYY-MM-DD`
`days`	integer	No	Days to include, `1`–`90` (default `7`). Used when explicit dates are omitted
`view`	enum	No	`summary` (hierarchical breakdown) or `timeseries` (flat per-day rows). Default `summary`
`download`	boolean	No	When true, returns a signed CSV download URL instead of JSON (default `false`)
`demo`	boolean	No	When true, returns auto-generated demo data (default `false`)
`sourceBreakdown`	boolean	No	Timeseries only. When true, returns one row per contributing inventory source. Default `false` preserves the legacy media-buy/package/date grain

Response

The example below uses illustrative, non-zero conversionValue, cpa, and roas values to show the response shape. See the note below the field table for how these fields behave when a seller has not reported conversion data.

Field	Type	Notes
`advertisers[]`	array	Advertiser-level breakdown
`advertisers[].metrics`	object	Reporting metrics for the advertiser (see below)
`advertisers[].mediaBuys[]`	array	Media-buy breakdown, each with `mediaBuyId`, `name`, `status`, `budget` (nullable), `inventorySourceId` (nullable), `metrics`, and `packages[]`
`advertisers[].mediaBuys[].packages[]`	array	Package breakdown with `packageId`, `productId`/`productName` (nullable), `metrics`
`totals`	object	Aggregated metrics across all advertisers
`periodStart` / `periodEnd`	string	Reporting window, `YYYY-MM-DD`

metrics carries raw counts (impressions, spend, clicks, views, completedViews, conversions, leads, videoCompletions, conversionValue) and calculated rates (ecpm, cpc, ctr, completionRate, cpa, roas, each nullable when undefined). conversionValue is the seller-reported revenue from conversions, always net (this surface never applies a buyer fee). cpa (spend / conversions) is null when there are no conversions. roas (conversionValue / spend) is null when spend is zero, or when there is no conversion signal at all — zero conversions and zero attributed value; it reports a true 0 only when conversions are real but their attributed value is zero. For view=timeseries, every row includes inventorySourceIds, the sorted, distinct source IDs carried by the delivery facts aggregated into that row. The existing inventorySourceId remains the deterministic legacy source. With sourceBreakdown=true, each row is source-grained, so inventorySourceId is the contributing source and inventorySourceIds contains that same single ID. These fields depend on the seller reporting conversion data. Where a seller reports none, conversionValue is 0 and cpa and roas are null.
