Credgenics Authentication API

  title: Credgenics Recovery Authentication API
  version: v1
  description: REST API for the Credgenics debt collection and loan recovery platform. Lenders integrate loan, customer, payment and transaction data, and receive collections outcomes back. Authentication is a client-credentials exchange that returns a short-lived API token supplied in the `authenticationtoken` header; every resource request carries the tenant's `company_id` as a query parameter. This specification was generated faithfully from the public developer documentation at https://docs.credgenics.com/ — it captures the documented endpoints, headers and parameters only; request/response bodies are documented narratively and are represented here as open objects.
