Sharethrough

Sharethrough is an omnichannel programmatic advertising exchange (SSP) for native, display, video and CTV inventory, and one of the largest independent ad marketplaces. Publishers monetise through the Prebid.js header-bidding adapter and server-to-server OpenRTB; demand partners buy through the exchange. Two API surfaces exist: a bearer-token Publisher Reporting API at publisher-api.sharethrough.com/v2 whose public reference is now behind a support-site sign-in, and the unauthenticated OpenRTB bid endpoint at btlr.sharethrough.com/universal/v1 used by the Prebid adapter. The company's richest machine-readable artifact is its IAB sellers.json (5,189 sellers). Sharethrough merged with Equativ in 2024 and has operated under the Equativ brand since June 2025; the Sharethrough exchange and its endpoints continue to run.

Sharethrough publishes 2 APIs on the APIs.io network. Tagged areas include Native Advertising, Programmatic Advertising, SSP, DSP, and OpenRTB.

The Sharethrough catalog on APIs.io includes 1 JSON-LD context.

Sharethrough’s developer surface includes documentation, support, engineering blog, authentication, and 22 more developer resources.

- name: Sharethrough Publisher Reporting API
  description: REST-ish reporting API enabling publishers to pull programmatic performance data for their Sharethrough inventory.
    A single POST /v2/programmatic endpoint takes a query object (startDate, endDate, groupBy, fields, filterBy) and returns
    CSV by default or JSON when negotiated by the Accept header. Bearer-token authentication. The v1 surface is retired and
    returns 503; the reference documentation now requires a support-site sign-in.

  description: OpenRTB 2.x bid endpoint at /universal/v1, integrated through the first-party sharethrough bidder adapter in
    Prebid.js (adapter version 4.3.0, IAB GVL ID 80). Supports banner, native and video/CTV, the price floors module, supply
    chain objects, SafeFrame, and GDPR/TCF, CCPA/USP and COPPA signalling. Publishers identify placements with a pkey; eqtvNetworkId
    routes the request to the Equativ exchange.
