  description: 'SAP Emarsys Core API (v2) provides programmatic access to the omnichannel customer engagement platform: managing contacts, contact lists, segments, and email campaigns. Authentication historically used WSSE; SAP Emarsys is moving the API surface to OAuth 2.0 / OIDC with JWT for v3 — both schemes are documented here.
