title: Flinks API
description: >-
Representative specification of the Flinks financial data API. Businesses
connect to consumer and business bank accounts to aggregate account,
transaction, and statement data, verify identity, and derive income,
credit-risk, and fraud analytics. A session is opened with the multi-step
/Authorize (MFA) endpoint using a LoginId returned by Flinks Connect; the
resulting RequestId is passed to subsequent data, enrichment, and analytics
endpoints. All calls are authenticated with a short-lived authorize token
supplied in the flinks-auth-key header.
