Vendors find they always need different or custom developed C2C APIs for different partners to meet business requirements. It is often time consuming and a heavy use of resources, when usually there are only slight differences among them. To fix the problem, Open Connectivity Foundation (OCF) launched the industry’s first C2C API standard in August 2020 – the Universal Cloud Interface (UCI), with an open source reference (“plgd”, https://github.com/plgd-dev/cloud), and a certification program.
In this white paper, we aim to provide readers with a comprehensive overview of the OCF UCI, including business scenarios (section 2), technical details (section 3), open source reference (section 4), and certification program (section 5).
