Mio

Mio is a collaboration interoperability platform that connects the leading enterprise messaging tools so teams on different platforms can work together without switching apps. Positioned as Google's official interoperability partner, Mio provides API-based middleware that relays messages, files, and directory information between Google Chat, Microsoft Teams, Slack, and Zoom Team Chat. Its products include Chat Sync (cross-platform messaging), External Chat Sync (partner/federated collaboration), Directory Sync (bidirectional user directory synchronization), and File Sync (shared Google Drive and SharePoint links). Mio runs as native middleware built directly with the platform vendors, never persistently stores user messages or files, encrypts data in transit with TLS 1.2+ and at rest with AES-256, and holds SOC 2 Type II certification with GDPR and CCPA controls. Mio is sold as an enterprise offering rather than a self-serve public developer API; this profile captures its public web, security, and support surface.

Mio is profiled on the APIs.io network. Tagged areas include Company, Collaboration, Interoperability, Messaging, and Enterprise.

Mio’s developer surface includes documentation, support, engineering blog, pricing, signup flow, and 10 more developer resources.
