Release 144

Interactive API documentation, the TCF v2.3 Disclosed Vendors check, SVG creatives, second-precision frequency capping, and large performance gains on list endpoints.

Reference network manager admin

Released: February — March 2026. This release delivers interactive API documentation, the Disclosed Vendors check that TCF v2.3 requires, and a long list of quality-of-life improvements across analytics, capping and creative handling.

New features

Interactive API documentation

The REST API is now fully documented with a machine-readable OpenAPI 3.0 specification and interactive Swagger UI: 647 endpoints and 1,891 parameters, every one with a description. Both require an authenticated session. As part of the same work, REST API error responses return a plain message instead of internal details. See the REST API reference.

CPA action pricing via API

A new REST endpoint creates and updates CPA action pricing on banners, accepting a price plus the action’s name or key — no UI round-trip needed for programmatic CPA setups.

Report generation audit trail

Analytics report generation — from the UI and the API — is now recorded in the action log with the requesting user, parameters and timestamp, giving network administrators visibility into who runs which reports.

Click tracking for programmatic video waterfalls

Clicks on DSP creatives inside multi-ad VAST responses are now recorded in analytics; previously only impressions were tracked for those creatives.

Improvements

TCF v2.3 Disclosed Vendors check — for the IAB’s February 2026 TCF v2.3 deadline, the consent check can also require the vendor in the consent string’s Disclosed Vendors segment. It is the Check disclosed vendors option in the GDPR settings, off by default; when it is on, a GDPR request whose consent string does not disclose the vendor is treated as having no consent. See GDPR and TCF consent.
SVG creatives — native banner icons and images can be uploaded as SVG. Files are sanitized on upload (scripts, event handlers and other active content are stripped) to prevent cross-site scripting. See native banners.
Minute-level time targeting — time range targeting accepts minute precision instead of whole hours.
Second-precision frequency capping — a new seconds period type enables sub-minute capping intervals (see the capping matrix).
Country groups everywhere — custom country groups and world regions now appear in analytics country filters, targeting dropdowns and pricing screens.
Modern browser detection — Brave, Samsung Internet, DuckDuckGo, Vivaldi, Arc and other contemporary browsers are now correctly detected for targeting and analytics.
More timezones in analytics — the timezone selector grew from 25 to 39 options, adding India (UTC+05:30), Nepal (UTC+05:45), Iran (UTC+03:30) and other half-hour-offset zones. New “Last week” and “Last 2 weeks” quick ranges were added too — see running reports.
Cleaner ad markup — unresolved $$CUSTOM_PARAM(...)$$ macros are stripped from served creatives instead of appearing as raw text.
Application placements — optional banner-size restriction for ad matching, and the API response now includes creative, click and impression tracking URLs.
Campaign exchange rate via API — campaign create/update endpoints accept an exchangeRate parameter.
Login page customization — a new white-label property hides the “Sign Up” link for networks without self-registration. See white label.
Retired invocation code formats — the outdated JSP, PHP, JavaScript sync/async and iframe sync/async code types were removed, simplifying placement setup. See invocation codes.
Better validation messages — limit dates beyond year 9999 are rejected up front, and attempting to delete global pricing explains why it isn’t permitted.

Bug fixes

Analytics returned empty results when grouping by placement labels and custom parameters at the same time.
Publisher-side piggyback pixel setup was broken in the configuration interface.
Native banner uploads via API skipped the file-size limit — image, icon and video uploads are now validated like everywhere else.

Under the hood

Platform upgrades and performance work — large banner and campaign lists over the API load much faster.
