conversions is always an array, regardless of any query parameter -- this is the standard "aggregate query, optional grouping" shape (SQL/pandas groupby, Google Analytics' Reporting API). With no interval, the array holds exactly one row, the grand total for the whole window. With interval, one row per bucket. There is exactly one response contract for this endpoint, never a plain case and a grouped case with different shapes.interval (including its absence) shares the same eligibility filters and per-conversion-day FX pricing as /conversions and /conversions/daily: a conversion counts if it has non-zero net revenue (refunds reported separately in refundsNumber/refundsAmount*, never netted in), is attributed via a click within 30 days (last-click, 30-day window), and its order is not a best-effort-detected cancellation. Every amount is priced at that conversion's own day's FX rate -- an hour-of-day or weekday bucket spans many calendar dates, so it is still priced day-by-day internally and summed, not priced once for the whole bucket.curl --location '/conversions/totals?dateFrom=2026-01-01&dateTo=2026-01-31&country=CZ%2CSK¤cy=EUR%2CCZK&interval=day' \
