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.
