Conduktor Gateway - Interceptors API

openapi: 3.0.1

  title: Conduktor API
  description: >-
    Unified specification of the Conduktor REST API surface, covering the Conduktor
    Console API (clusters, certificates, users, groups, RBAC permissions, and
    declarative Self-Service resources) and the Conduktor Gateway API
    (interceptors, virtual clusters, service accounts, and tokens). Console
    endpoints authenticate with an admin-generated Bearer API key; Gateway admin
    endpoints authenticate with Basic auth. Host names are deployment-specific.
