  description: >-
    A single static per-business API token. Float's OpenAPI declares this scheme in
    components.securitySchemes but declares NO top-level `security` and no per-operation `security`, so the
    contract never states which operations require it — a generated client sends no credential at all. In
    practice every operation except getOpenAPI requires the token.

token_properties:
  scope: business
  granularity: all-or-nothing
  prefix: none published
  expiry: not documented
  rotation: not documented
  test_variant: none
  note: >-
    There are no scopes, no permissions and no read-only token type. A token that can read every card
    transaction can also issue cards (createCard), create card limits (createCardLimit), create users
    (createUser) and delete tax codes and custom fields. For a spend-management platform that is a wide blast
    radius from one secret, and it is the strongest authorization finding in this profile.
environments:
- name: production
  base_url: https://api.floatfinancial.com
  token_type: live
  note: >-
    The only environment. Float's FAQ states it offers no sandbox or test environment, so there is no test-mode
    key and no prefix by which a leaked token could be triaged as harmless.
anonymous_endpoints:
- operationId: getOpenAPI
  path: /v1/openapi
  method: GET
  status: 200
  note: The OpenAPI document is served without credentials — the only anonymous operation.
failure_behaviour:
  status: 401
  body: '{"error":"UNAUTHORIZED","message":"Incorrect authentication credentials.","docs":"https://docs.floatfinancial.com"}'
  observed_from: live GET https://api.floatfinancial.com/v1/cards with no Authorization header
  declared_in_spec: false
  note: 401 is returned live but is not declared on any of the 71 operations in the spec.

  note: >-
    No OAuth and no OIDC. scopes/float-financial-scopes.yml is deliberately not written — there is no scope
    surface to record.
platform_sso:
  saml: true
  mfa: true
  note: >-
    SAML SSO (Professional and Enterprise plans) and MFA (all plans) secure the Float web app for humans. They
    do not apply to API tokens, which remain unscoped static secrets.

remediation_for_provider:
- >-
  Declare a global `security` requirement referencing bearerToken so generated clients actually send the
  credential — the scheme is defined but never applied.
- Declare the 401 response with a schema on every authenticated operation.
- Introduce scoped or read-only tokens; today one token grants card issuance and user creation.
- Publish token expiry and rotation guidance, and a token prefix so leaks are identifiable.
