Exports error events in CSV format.

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.

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.

Columns to include in the response (required). This is a repeated query parameter — use column=visits&column=clicks, NOT comma-separated. Valid columns differ per report type (aggregated /report, per-conversion /report/conversions, error /report/errors).

Common mistakes returning 400: deviceType (use device), and requesting a Name variant for a self-labeling dimension — region, city, os, browser, isp, mobileCarrier are already human-readable, so there is no regionName/cityName/osName/browserName column. (Code/name pairs like countryCode/countryName and connectionType/connectionTypeName are the exception — those Name columns exist.)

Call GET /column/info for the authoritative list of valid columns for this account. The column sets named in each endpoint's own documentation are guidance/examples, not the complete list.

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.

Sort direction. Default: desc (descending).
