description: Fluxx is a cloud grants management platform for foundations, government
  agencies, corporations, and nonprofits, covering the full grant lifecycle from
  funding announcement through pre-award applications, post-award payments, and
  measurement and evaluation. Fluxx Grantmaker includes a RESTful API (REST API v2)
  available to customers for building custom integrations with financial, CRM, and
  business-intelligence systems. The API is exposed per-client on each customer's
  own Fluxx instance under https://{client}.fluxx.io/api/rest/v2, is authenticated
  with OAuth 2.0 credentials created in that instance, and is driven by a dynamic,
  instance-specific data model whose reference documentation is generated at
  /api/rest/v2/doc for each deployment. Because the surface is per-instance and
  gated behind an authenticated customer deployment, the endpoints below are
  honestly modeled from Fluxx's documented REST v2 conventions rather than pulled
  from a single public reference.

    (filter, e.g. grant_id eq R-2024-00003), and pagination (page, per_page).

    and available models are defined per customer instance and are gated behind
    that instance.

    register an application at /oauth/applications on their instance to obtain a

    /oauth/token. Endpoints are modeled from Fluxx's documented OAuth flow; the
    authorization surface lives on each customer's own instance.
