name: TripleLift Reporting API Changelog
description: >-
  TripleLift publishes a dated changelog for the Reporting API on its supplier
  documentation site. Ten entries are indexed. The overwhelming pattern is additive
  — new report dimensions and metrics — with a single breaking rename. No changelog
  exists for the TLX exchange endpoint or for the platform federated API.

    note: >-
      The index in llms.txt lists this entry as 2026-01-12 but its URL slug is
      /changelog/2026-11-12. The date shown and the date in the permalink disagree;
      recorded as published rather than reconciled.
  - date: '2025-11-13'
    url: https://supply-docs.triplelift.com/changelog/release-candidate
    breaking: true
    type: breaking-rename
    surfaces: [publisherNetworkReport, ctvPublisherNetworkReport]
    highlights:
      - Renamed dimension dsp_seat_id to dsp_seat.
      - Changed the buyer seat ID data type from integer to string, fixing a defect where the dimension failed when used as an IdFilter.
      - dsp_seat is now the dimension name and the NameFilter.
    note: >-
      The only breaking change in the published history. It renamed and retyped a
      field first shipped 2025-05-26, and was announced at the time of the change
      with no deprecation window and no sunset date. The entry is filed under the
      slug "release-candidate" rather than a date, so the permalink itself carries
      no date.

observations:
  - >-
    Cadence is roughly every six to eight weeks and has been sustained for over a
    year, which is a real signal of an actively maintained API.
  - >-
    Every entry describes report dimensions and metrics. Not one entry describes a
    new operation, an auth change, a rate-limit change or a lifecycle event, which
    matches the shape of the surface: one GraphQL endpoint whose schema grows
    sideways rather than a REST API that grows new paths.
  - >-
    Dimension naming is inconsistent across entries — SCREAMING_SNAKE in newer
    entries, lower_snake in 2025 entries — and one shipped dimension name contains
    a typo (JOUNCE_CLASSIFICIATION). Because the schema is not introspectable
    anonymously, a consumer cannot resolve casing from the contract and must trust
    the changelog prose.
