description: Zeffy is a 100% free fundraising platform for nonprofits - donation forms, event ticketing, peer-to-peer campaigns,
  memberships, e-commerce, and donor management - with no platform, transaction, or credit-card fees, funded entirely by optional
  tips from donors. Zeffy exposes a free public REST API that gives organization admins read-only access to their Payments,
  Contacts, and Campaigns data (base https://api.zeffy.com/api/v1), authenticated with a per-organization API key sent as
  a Bearer token, plus outbound webhooks that POST payment details to a configured URL when a payment is completed. Zeffy
  also integrates via Zapier, QuickBooks, and WordPress.

  description: Outbound webhooks configured under Settings then Integrations. When a payment is completed, Zeffy sends an
    HTTP POST with the full payment details to the organization's configured URL, enabling thank-you workflows, CRM/accounting
    sync, and internal notifications. This is Zeffy-to-consumer HTTP notification, not an inbound API surface.
