name: Giveffect
description: 'Giveffect is an all-in-one nonprofit management platform that combines ten seamlessly connected systems into
  a single suite for charitable organizations: constituent relationship management (CRM), online fundraising and donation
  processing, peer-to-peer and event fundraising, volunteer management, membership management, email and marketing communications,
  wealth screening and major-gifts tools, website building, and smart automation and workflows. Giveffect exposes an optional
  "open API" on its enterprise (Ultimate+) tier for integrating the platform''s donor, donation, volunteer, and campaign data
  with external systems, and ships prebuilt integrations with QuickBooks Online, DonorSearch, Double the Donation, Zoom, The
  Giving Block, and Ez Scan. The company was surfaced as a Y Combinator portfolio company and enriched into the API Evangelist
  network.'

  note: Three named tiers (Lite, Ultimate, Ultimate+), none with a published price — every tier reads "Contact us" and routes
    to Schedule a Call. The API itself is available only on Ultimate+ ("Open API and custom integration"); the Ultimate tier
    is explicitly "All system features (excludes open API)". A 14-day platform free trial is offered after a demo, but it
    does not include API access.

  description: 'Giveffect''s "open API" is available on the enterprise Ultimate+ plan and provides programmatic access to
    platform data (donors, donations, volunteers, campaigns, and events). It is explicitly carved out of the tier below it
    — the Ultimate pricing card reads "All system features (excludes open API)" — and only Ultimate+ lists "Open API and custom
    integration", so entitlement is a plan feature granted through sales rather than a self-serve signup. No public developer
    documentation, OpenAPI specification, SDK, or Postman collection is published anywhere; https://www.giveffect.com/api
    302s to the customer sign-in page. The base host is live and JSON-native: its root is an operational health endpoint returning
    {"status":{"code":200,"message":"OK - Systems operational"}}, unknown paths return {"error":{"code":404,"message":"Not
    Found - Invalid resource"}}, and every response carries an X-Request-Id correlation uuid (Rails behind Phusion Passenger).

  note: Contract discovery (STEP 0b) missed on every host; the API is a tier-gated enterprise feature with no public reference.
    Removed a prior-round `Security` pointer that credited security_disclosure to a marketing page with no disclosure mechanism
    (see security/giveffect-vulnerability-disclosure.yml).
x-coverage:
  state: gated
  reason: customer-only-docs
  detail: Giveffect's API is a paid feature of the Ultimate+ tier only — the Ultimate pricing card reads "All system features
    (excludes open API)" — and https://www.giveffect.com/api 302s to the customer sign-in page, so the reference requires
    an active subscription; api.giveffect.com is live and answers JSON but returns its 404 envelope for /openapi.json, /swagger.json,
    /api-docs, /graphql, /mcp and every /.well-known/ path.
