Returns errors grouped by error category.

Free-text substring search over NAME columns only (campaignName, offerName, ...). NOT for ids and NOT exact — a fragment can match several rows or none. To scope a report to a specific entity by id, use the drilldown filters filter1/filter1Value (e.g. filter1=campaignId, filter1Value=<id>); never put an id here.

Pagination offset (zero-based). Default: 0.

Time zone for date aggregation, e.g. 'America/New_York', 'Europe/Warsaw', or 'Etc/GMT'. Default: Etc/GMT. Affects how day, dayOfWeek, and hourOfDay boundaries are calculated.

Maximum rows to return per request. Default: 100. Values above the per-account cap are silently capped; totalRows always reflects the true count. Use offset to page through.

Start date/time (inclusive, required). ISO 8601 format, e.g. 2026-03-01T00:00:00Z.

Must be aligned to an hour boundary — minutes and seconds must be zero.

The date range is half-open [from, to) — 'from' is included in results.

End date/time (EXCLUSIVE, required). ISO 8601 format. The date range is half-open [from, to) — 'to' is NOT included.

Must be aligned to an hour boundary — minutes and seconds must be zero.

To query the full day of March 5, set to=2026-03-06T00:00:00Z (next day).

Column name to sort by. Can be any valid metric or dimension column. Default: visits.

Workspace IDs to filter by. Only returns data for campaigns in the specified workspaces.
