name: Giveffect API authentication
description: >-
  Giveffect does not publish how its API is authenticated. There is no developer
  portal, no auth page, no OAuth or OIDC discovery document, and no OpenAPI with
  securitySchemes to derive from. Probing the production API host anonymously
  does not reveal the scheme either: unknown paths return 404 rather than a 401
  with a WWW-Authenticate challenge, so the service does not advertise its
  challenge to an unauthenticated caller. NO Authentication pointer is emitted
  from this file — it records that the auth model is undocumented, which is the
  opposite of authentication_documented.

  note: >-
    GET https://api.giveffect.com/v1/donors returns
    {"error":{"code":404,"message":"Not Found - Invalid resource"}} with no
    WWW-Authenticate header. A 401 could not be provoked anonymously.
provisioning:
  model: enterprise-provisioned
  tier: Ultimate+
  evidence: >-
    "Open API and custom integration" is listed only on the Ultimate+ pricing
    card; the Ultimate card reads "All system features (excludes open API)".
    Access is therefore granted by Giveffect sales/success, not self-serve.

platform_auth:
  note: >-
    Platform (not API) authentication is a username/password login at
    https://app.giveffect.com, and two-factor authentication was shipped to the
    product as a 2025 update. This says nothing about how API callers
    authenticate.

scopes:
  applicable: false
  note: >-
    No OAuth surface exists, so scopes/ is skipped rather than written empty.
