The Trade Desk

aid: trade-desk
name: The Trade Desk
description: >-
  The Trade Desk is an independent, omnichannel demand-side platform (DSP) for
  programmatic advertising, headquartered in Ventura, California. Its
  cloud-based platform — Kokai (the current flagship, succeeding Solimar) —
  lets agencies, brands, and trading desks buy and optimize digital ad
  inventory across connected TV (CTV), audio, mobile, video, native, display,
  and digital out-of-home. The Trade Desk positions itself as the
  buy-side counterweight to the walled gardens by championing the open
  internet through OpenPath (direct publisher integrations that bypass SSPs)
  and Unified ID 2.0 (UID2), an open-source, deterministic identity framework
  governed by the IAB Tech Lab. The company also stewards EUID (UID2's
  European equivalent), the Galileo first-party data activation framework,
  and Koa — its in-platform AI used for forecasting, bidding optimization,
  and audience modeling. Programmatic developers integrate via the TTD
  Workflows API (REST + GraphQL for campaign, ad group, and creative
  management), the Data API (advertiser/third-party data ingestion, offline
  conversions, deletion/opt-out), the Real-Time Conversion Events API (RTCE),
  and the OpenSincera data-quality APIs (acquired May 2024). Official SDKs
  are published in Python, Go, and Java and are Speakeasy-generated from
  OpenAPI specs. Most documentation lives behind the Partner Portal
  (partner.thetradedesk.com) but a public docs surface is exposed at
  open.thetradedesk.com. The Trade Desk is publicly traded (NASDAQ: TTD).

    The Workflows API exposes the high-level campaign, ad group, creative,
    and bulk-job operations that previously required navigating the legacy
    Platform API. It blends REST and GraphQL surfaces (including a generic
    GraphQL passthrough and bulk query jobs) and is the recommended modern
    integration path for new partners.

    Documentation is gated behind the TTD Partner Portal. New integrations
    are generally steered to the Workflows API; Platform remains the
    reference for low-level objects and reporting endpoints.

    Unified ID 2.0 is an open-source, deterministic identity framework
    seeded by The Trade Desk and now governed by the IAB Tech Lab. UID2
    resolves hashed email addresses and phone numbers into rotating
    tokens that publishers, DSPs, SSPs, and measurement vendors can use
    for addressable advertising without third-party cookies. The EUID
    variant provides a GDPR-aligned European deployment.
