  title: API Evangelist enhancements for Digital E&S API
  version: 1.0.0
extends: amtrust-financial-services-digital-es-api-openapi.json
x-generated: '2026-09-02'
x-method: generated
x-source: openapi/amtrust-financial-services-digital-es-api-openapi.json (harvested verbatim from AmTrust
  Azure API Management, 2026-09-02)
x-note: 'Non-destructive enhancements API Evangelist would apply to the AmTrust contract. The original
  document in openapi/_original/ is never mutated. The dominant fix is the missing OpenID Connect security
  scheme: AmTrust requires BOTH an APIM subscription key AND a bearer token from its IdentityServer, and
  only the subscription key is declared in the spec, so a generated client 401s.'
