notes: >-
  The Wacai Open Platform (挖财开放平台) does not publish an OpenAPI document, so this
  profile is captured from the first-party SDK documentation rather than derived
  from a spec. Access is via an app credential (app_key / app_secret) issued by
  the open platform, with per-request HMAC signing. Older SDKs additionally use a
  token service (access_token / refresh_token); the higher-version all-in-one SDK
  connects directly to the gateway without a token.
summary:
  types:
    - app-credential
    - request-signature
    - bearer-token
  credential: app_key + app_secret (issued by the Wacai Open Platform)
  signing: [MAC, RSA]
  token_service: true
schemes:
  - name: app_key
    type: apiKey
    in: body
    param: app_key
    description: >-
      Application key identifying the caller, issued on registration with the
      Wacai Open Platform. Paired with app_secret for request signing.
  - name: app_secret_signature
    type: signature
    algorithms: [MAC, RSA]
    encoding: base64
    description: >-
      Every request to the API gateway is signed with app_secret. Default
      algorithm is MAC (HMAC); RSA is supported via a configured public/private
      key pair. Responses may optionally be signature-verified (验签), and payloads
      optionally encrypted (DES) via the gateway SDK filter chain.
  - name: access_token
    type: bearer-token
    obtained_via: wacai-token-sdk (TokenService.Get / TokenService.Refresh)
    refreshable: true
    description: >-
      Token-based access used by older SDKs: an access_token is acquired from
      app_key/app_secret and refreshed via refresh_token. The higher-version
      all-in-one SDK bypasses the token and connects directly to the gateway.
      Callers are advised to cache the token (memcache/redis) and to retry
      requests themselves after an automatic token refresh.
