Introduction
What HellOOpass is and where to go next.
HellOOpass is an operating system for communities — the digital infrastructure that lets cooperatives, unions, associations, and member groups trade, pay, and manage finances together through a secure, borderless network.
This documentation covers the HellOOpass payments API: how developers integrate payments into the applications their communities use.
