description: >-
  Authentication profile for HKEX's one documented RESTful API, the FINI API
  Gateway (IPO settlement). Access is restricted to registered market
  participants (HKSCC Participants, FINI banks, sponsors, advisers). Clients
  authenticate with OAuth 2.0 JWT-bearer grants (RFC 7523) against the HKEX
  Access Management (ForgeRock OpenAM) server, presenting two RS256-signed
  JWTs — an Agent Profile JWT (G1) and a Machine Profile JWT (G2) — whose RSA
  JSON Web Keys (RFC 7517) are pre-registered on the HKEX Access Management
  Portal. The AM server returns a FINI API JWT access token that is passed as
  a Bearer token on every FINI API call. The OMD market-data feeds and the
  Data Marketplace are not HTTP APIs and use licensing agreements / SFTP
  credentials instead.
summary:
  types: [oauth2]
  oauth2_flows: [jwt-bearer]
  transport: TLS 1.2 minimum; PII request/response fields additionally use end-to-end field-level encryption
schemes:
- name: FINI OAuth 2.0 JWT-bearer
  type: oauth2
  flow: 'urn:ietf:params:oauth:grant-type:jwt-bearer'
  client_assertion_type: 'urn:ietf:params:oauth:client-assertion-type:jwt-bearer'
  token_host: https://openam.connect.hkex.com.hk
  token_path: /openam/oauth2/eu/access_token
  assertions:
  - name: Agent Profile JWT (G1)
    algorithm: RS256
    sub: user's Company ID in HKEX Client Connect
    registered_key: Agent RSA JWK registered on HKEX Access Management Portal
  - name: Machine Profile JWT (G2)
    algorithm: RS256
    registered_key: Machine RSA JWK registered on HKEX Access Management Portal
  constraints:
  - Agent/Machine Profile JWT expiration must be within 30 minutes or the AM server rejects it
  - Access token expires_in 30 (seconds, per sample response); scope value returned is the Company ID (e.g. CP00001)
  - Registered JWKs expire and must be rotated before expiry
  usage: 'Send the FINI API JWT access token as "Authorization: Bearer <token>" on every FINI API request'

notes:
- No self-serve signup — credentials are provisioned through HKEX Client Connect / Access Management for registered participants only.
- The OpenAM host is not reachable from the public internet; OIDC discovery could not be probed anonymously.
- OMD-C / OMD-D datafeeds are licensed binary multicast feeds (no HTTP authentication surface); Data Marketplace delivery uses SFTP or cloud-to-cloud transfer arranged with the datamarketplace@hkex.com.hk team.
