NFON AG is a European provider of cloud telephony and unified communications (UCaaS/CPaaS), headquartered in Munich and serving businesses across 15+ European countries. Its Cloudya cloud phone system and related products deliver business voice, video, contact centre and AI-assisted communication. For developers and integration partners, NFON publishes a set of RESTful JSON APIs hosted from the NFON-AG GitHub organisation: the flagship PBX Configuration API (OAuth 2.0, ~480 operations for provisioning tenants, extensions, devices, queues, groups, IVRs, phone books, licences and more — the successor to the legacy Service Portal API), the CTI API (server-to-server call control and Server-Sent-Event call/state streaming), and the Call History API offered under "Login with NFON" (OAuth 2.0 Authorization Code + PKCE) for retrieving, streaming and deleting call records with transcriptions and summaries. Use of the APIs is free of charge; access is provisioned by contacting integration@nfon.com.
