Yahoo Ad Tech DataX API

Partner-facing data-exchange API for uploading and managing audience taxonomies, user and audience membership, fees and measurement feeds, plus a Real-Time API (specification v2.0), a Partner Match data-in API and exposure-log delivery to Amazon S3, Microsoft Azure and Google Cloud. Onboarding is a manual RSA key exchange with Yahoo data operations. It is the only Yahoo API surface with hypermedia affordances, returning typed link relations under datax.yahooapis.com/rels/ and opaque resource links. GDPR handling - jurisdiction flags, IAB TCF consent purpose bits and opt-out semantics - is documented in depth.
