api: Acorn Finance Partner API
versioning:
  scheme: none
  detail: >-
    No version segment, header or parameter is present in the documented surface.
    Endpoints are served from the host root. Widget distribution is separately
    versioned (the Payment Amount Widget is on a /paw/v5/ path with pinnable
    /paw/v5/versions/<x.y.z>/ builds) but the REST API is not.

deprecation_policy:
  published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  note: >-
    No deprecation or sunset policy is published for the Acorn Finance partner API,
    and no Deprecation or Sunset response header is documented. No Deprecation
    pointer is emitted.
  caution: >-
    developer.acornfinance.com resolves to a Stoplight-hosted portal that carries
    Acorn Finance branding in its head (title, favicon and logo from
    www.acornfinance.com) but rendered the API catalogue of an unrelated company,
    Autopay.io (Norwegian parking payments), in its body when probed on 2026-09-06 —
    including an "API Deprecation" page. That content is NOT Acorn Finance's and was
    deliberately excluded from this profile. Acorn Finance's real developer
    documentation is docs.acornfinance.com.
status_page:
  published: false
  url: null
  note: >-
    No status page found. status.acornfinance.com does not resolve; no status or
    uptime link appears in the documentation or the site footer. No StatusPage
    pointer is emitted.
sla:
  published: false
  note: >-
    No uptime or latency SLA is published. The only quantified commitment in the
    partner documentation is an onboarding one — API credentials are issued "within
    48 hours Mon-Fri" of the credential request email.
credential_lifecycle:
  rotation_interval_days: 90
  discovery_endpoint: GET /active_credentials
  expiry_field: expires_on
  detail: >-
    Credentials carry created_at and expires_on and are rotated every 90 days. This
    is the only recurring lifecycle event the provider publishes and the only place
    the API returns a forward-looking date.

application_lifecycle:
  states:
  - NO OFFER
  - OFFERED
  - SELECTED
  - FUNDED
  - EXPIRED
  detail: >-
    Loan applications move through a fixed status set, surfaced as loan_status on
    GET /company_applications and as processStatus on the partner postback. EXPIRED
    is a terminal state, but no expiry window is published.

  note: No dated changelog or release-notes page is published for the partner API.
