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). type: Index position: Provider access: 3rd-Party image: https://kinlane-productions.s3.amazonaws.com/apis-json/apis-json-logo.jpg tags: - Advertising - Programmatic Advertising - Demand-Side Platform - DSP - AdTech - Connected TV - CTV - Identity - Unified ID 2.0 - UID2 - OpenPath - Kokai - Koa AI - Galileo - Sincera - Open Internet - Real-Time Bidding - Open Measurement url: https://raw.githubusercontent.com/api-evangelist/trade-desk/refs/heads/main/apis.yml created: '2026-05-25' modified: '2026-05-25' specificationVersion: '0.20' apis: - aid: trade-desk:trade-desk-data-api name: The Trade Desk Data API tags: - Advertising - Data - Audience - Conversions - Privacy humanURL: https://open.thetradedesk.com/advertiser/docsApp/GuidesAdvertiser/data properties: - url: https://open.thetradedesk.com/advertiser/docsApp/GuidesAdvertiser/data/doc/post-data-advertiser-firstparty type: Documentation - url: https://open.thetradedesk.com/provider/docsApp/GuidesProvider/audience/doc/post-data-thirdparty type: Documentation - url: https://open.thetradedesk.com/advertiser/docsApp/GuidesAdvertiser/data/doc/post-providerapi-offlineconversion type: Documentation - url: openapi/trade-desk-data-api-openapi.yml type: OpenAPI - url: https://github.com/TheTradeDesk/ttd-data-python type: SDK name: Python SDK description: >- Ingest first-party advertiser audience data, third-party provider audience data, and offline conversions (CAPI-style), and submit data-subject deletion / opt-out requests across advertiser, merchant, and provider contexts.
