Moving from the legacy mobile export

For customers who integrated the mobile export before October 2026. The current mobile export is requested with "version": "v2" on Create an export. Your existing job keeps returning the legacy export, unchanged, until a retirement date we will agree with you. Desktop is unchanged.

What changes

Column Change What to do
demographics.date_of_birth Removed Use age in demographics. The current export carries no date of birth.
evidence_metadata Removed Use brand, brand_evidence and ad_text.
brand New The advertiser by its public name.
brand_evidence New The exact text the brand was read from.
other_brands New Other brands named in the ad, [] when there are none.
industry New Top level of the IAB Ad Product Taxonomy 2.0.
industry_path New The full IAB category.
ad_text New The advertiser's own words in the ad.
creative_url New Link to the ad's image or video file.

Every other column keeps its name and type.

What the rows now mean

last_seen is when the ad left the screen: the device's next screen change after the ad was last captured, in the same app or another, at most 60 seconds later and 10 minutes after first_seen, and earlier when the camera stopped. In the legacy export it was the last capture of the ad. duration_s, eyetracker_enabled, fixation_duration_ms and is_fixated cover first_seen to last_seen, so the same impression shows longer time on screen and more fixation than in the legacy export. Compare within one export, not across the two.

impression_id values do not pair between the two exports, and a rebuilt day can give its rows new ids. Merge by day, not by id.

How to switch

  1. Add "version": "v2" to the create call. Same key, same endpoints, same files.
  2. Update your reader. Drop date_of_birth and evidence_metadata; add the seven columns.
  3. Replace by day. Delete the days in each batch from your table, then insert, as in the loader.
  4. Fetch from 13 October 2026. v2 data starts there. Earlier days are being added, and the first day moves back as they arrive; a from_date before it is a 400 V2_FROM_DATE_NOT_AVAILABLE with the first day in available_from.
  5. Keep the old job until the retirement date. Tell us at data@attexdata.ai when you have switched.
