Connector SDK

Fivetran Connector SDK

Connector SDK connectors now support VPN tunnel as a connection option. A VPN tunnel provides a secure, encrypted site-to-site VPN connection between your network and Fivetran's network, enabling your connector code to access your source over a private network. You must have an Enterprise or Business Critical plan to use a VPN tunnel connection for Connector SDK.
