Fundraise Up Supporters API

openapi: 3.0.3
info:
  title: Fundraise Up REST API
  description: >-
    The Fundraise Up REST API gives programmatic access to fundraising data for a
    nonprofit's Fundraise Up account. It is resource-oriented, uses predictable
    URLs, accepts JSON-encoded request bodies with a Content-Type of
    application/json, and returns JSON responses. The API lets you work with
    Donations, Recurring Plans, Supporters (donors), and Events (an audit log),
    and generate Donor Portal access links. Donations and recurring plans can be
    created and updated, but updates are only allowed within 24 hours of creation;
    supporters and events are read-only. List endpoints use cursor-based
    pagination via the limit, starting_after, and ending_before query parameters.
    All requests authenticate with an API key (created in the dashboard under
    Settings > API keys) passed as an HTTP Bearer token. Fundraise Up does not
    expose a WebSocket API; event-based syncing is done by polling the Events
    resource. Field-level request and response schemas are intentionally left open
    here and should be reconciled against the hosted reference at
    https://api.fundraiseup.com/v1/docs/.
