notes: >-
  The M-Files Web Service (MFWS) REST API is hosted per M-Files Server (on-prem or
  M-Files Cloud vault), so endpoints are relative to the customer's Web Access root
  (e.g. /REST/...). Authentication is session/token based rather than a fixed public
  OAuth server; OAuth bearer is supported where the vault is configured for it.
summary:
  types: [oauth2, apiKey, http]
  api_key_in: [header]
  api_key_header: X-Authentication
  oauth2_flows: [authorizationCode]
schemes:
  - name: AuthenticationToken
    type: apiKey
    in: header
    header: X-Authentication
    obtain: POST /REST/server/authenticationtokens
    description: >-
      Recommended method. POST username, password, and vault GUID (in braces) to
      /REST/server/authenticationtokens; the JSON response returns a token value
      passed on every subsequent request via the X-Authentication header. Optional
      Expiration (ISO 8601) and SessionID. A 403 indicates an expired token.
  - name: OAuth2Bearer
    type: oauth2
    scheme: bearer
    description: >-
      OAuth 2.0 access token passed as Authorization: Bearer <access-token>. Used
      when the vault / M-Files Server is configured with an OAuth identity provider
      (e.g. Azure AD / Microsoft Entra ID).
  - name: HttpHeaderCredentials
    type: apiKey
    in: header
    header: X-Username
    description: >-
      Not recommended. Credentials passed directly as X-Username, X-Password, and
      X-Vault headers on each request.
  - name: CookieSession
    type: http
    scheme: cookie
    description: >-
      ASP.NET session cookie returned after authentication, typically used for
      single sign-on scenarios; preserve cookies for Multi-Server Mode stickiness.
  - name: SingleSignOn
    type: oauth2
    description: >-
      Single Sign-On (SSO) against the configured identity provider; see
      https://developer.m-files.com/APIs/REST-API/Authentication/Single-Sign-On/
  - name: PreSharedKeys
    type: apiKey
    in: header
    description: >-
      Pre-shared key authentication; see
      https://developer.m-files.com/APIs/REST-API/Authentication/Pre-Shared-Keys/
