  EY does not publish a public developer portal, OpenAPI specs, or partner API
  documentation. EY operates proprietary technology platforms (EY Helix
  analytics, EY Atlas research, EY Canvas audit, EY Intelligent Tax) but those
  systems are surfaced to clients through engagement teams and the EY Client
  Portal rather than as self-service developer APIs. Any technical integrations
  are arranged through engagement contracts and EY Technology Consulting.
