Yahoo DSP does not issue a long-lived refresh token. Instead, Adriel signs in with the stored credentials and obtains a fresh, short-lived access token automatically whenever the current one expires. The renewal happens in the background on each sync, so dashboards keep loading without a manual reconnection. If a dashboard does start returning authorization errors, the underlying credentials or account access have likely changed on the Yahoo side; reconnecting the data source resolves it. See [How to connect Yahoo DSP to Adriel](/data-sources/o-z/yahoo-dsp/how-to-connect). ## Why are reach or unique-household totals higher than expected over a long date range? Yahoo DSP report data comes from cached daily snapshots, and metrics based on uniqueness are counted per day. This includes reach, unique households, and average frequency per household. When a widget spans more than one day, Adriel sums the daily values, so a household or person counted on two separate days is counted on each of those days. Across a long range, the total can therefore look inflated relative to the true unique audience. For an accurate unique count, view these metrics one day at a time, or interpret multi-day figures as a sum of daily uniques rather than a de-duplicated total. The affected metrics are listed in the [Yahoo DSP data reference](/data-sources/o-z/yahoo-dsp/data-reference). ## Why are some viewability or completion metrics missing from my report? Yahoo DSP exposes different metric sets depending on the ad account's access type. Seat access provides the full set, including video completion counts and rates, viewability (Yahoo and Moat), frequency, and seat-level fees. General Access Network (GAN) access is limited to core delivery, clicks, conversions, VCPM, CPCV, and tracked actions. If video completion or viewability metrics return no data, the ad account most likely uses GAN access, where those metrics are not available. Core delivery and conversion metrics remain available under both access types. The metric catalog and its groupings are documented in the [Yahoo DSP data reference](/data-sources/o-z/yahoo-dsp/data-reference). ## Why is older Yahoo DSP data sometimes incomplete? Yahoo DSP is a cache-only source, so every dashboard query reads Adriel's cached daily snapshots rather than fetching live from Yahoo. Adriel imports up to 730 days of history when the data source is first connected, and because Adriel caches the data, the longer the data source stays connected, the more historical data is stored. Each refresh re-syncs only the most recent days, so very old rows reflect the last time they were synced and may be incomplete or not fully accurate due to legacy caching behavior. Recent data within the sync window is the most reliable. For the refresh schedule and sync window, see the [Yahoo DSP data reference](/data-sources/o-z/yahoo-dsp/data-reference). ## How do I report on CTV or DOOH metrics like unique households? Some Yahoo DSP metrics apply only to specific placement types. Unique households and average frequency per household come from connected TV (CTV) inventory, while audience impressions and average impression multiplier come from digital out-of-home (DOOH) inventory. These metrics return data only for campaigns running on those placement types and appear empty elsewhere. To isolate the relevant inventory, add the **Channel** breakdown to the widget and filter to the CTV or DOOH channel, then add the placement-specific metric. Note that average frequency per household may be limited for EU audiences due to privacy restrictions. The full list of channel-specific metrics is in the [Yahoo DSP data reference](/data-sources/o-z/yahoo-dsp/data-reference). ## Related Metrics, breakdowns, refresh cadence, and limits for Yahoo DSP.
