TapAd

Tapad is a digital identity and cross-device graph technology company, founded in 2010 and headquartered in New York City. Its flagship product, the Tapad Graph, is a probabilistic device graph that lets marketers, agencies, and platforms recognize a brand's customer or related household across the many devices they use, powering programmatic targeting, media measurement, attribution, and personalization. Tapad was acquired by the Norwegian telecom Telenor in 2016 and then by the credit-and-data company Experian in 2020, and by 2026 its product and company pages redirect into Experian's Consumer Sync marketing suite while docs.tapad.com redirects to Experian's client-only Marketing Knowledge Base. Tapad runs no public developer program — no portal, no OpenAPI, no pricing and no self-service signup — but it does still operate two live first-party HTTP endpoints, the Tapestry Web API and an event tracking beacon, both requiring a partner id that only Tapad can issue, and it published four open-source mobile SDKs that it has since archived as unmaintained. It was added to the API Evangelist network as a portfolio company of Battery Ventures.

TapAd publishes 2 APIs on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Identity, and Cross-Device.

TapAd’s developer surface includes authentication and 13 more developer resources.

- name: Tapad Tapestry Web API
  description: The Tapestry Web API is Tapad's cross-device identity and audience endpoint. A client sends a GET request carrying
    a Tapad-issued partner id plus one or more device or user identifiers, and Tapad resolves them to a device clique in the
    Tapad Graph. The same call can read back key/value data, audience tags, resolved identifiers and the list of devices in
    the clique, and can write data and audience membership onto that clique. All input travels in the query string under a
    ta_ prefix; the response is a flat JSON object. Errors are returned with HTTP 200 and a proprietary errors[] envelope
    rather than a status code. The endpoint is live and answering as of 2026-08-12, but the only published clients for it
    are SDKs Tapad archived in 2014.

  description: Tapad's app install and in-app event tracking beacon, documented in the company's own open-source mobile SDKs
    as the RESOURCE_URL for the event-tracking module. A client sends a GET request with a Tapad-issued partner id and event
    parameters; the service answers HTTP 200 with a 1x1 PNG. The companion ad-serving endpoint that shipped in the same SDK,
    swappit.tapad.com, no longer resolves in DNS. The event endpoint is live as of 2026-08-12.
