    description: >-
      All Fidel API requests authenticate with a secret API key passed in the
      Fidel-Key HTTP header. Keys are environment-scoped: Test keys access the
      test environment and Live keys access the live environment. There are two
      key classes - API keys (server-side, direct REST API access) and SDK keys
      (used to link the Web/iOS/Android/React Native SDKs to your account).
      Keys are created, viewed, and revoked in the Fidel Dashboard under
      Account Settings > Plan.
