What this skill does
Phaxio Phaxio is a cloud-based fax API that allows developers to send and receive faxes programmatically. It eliminates the need for traditional fax machines and phone lines.

The output contains the new connection id. This is the fastest way to get a connection. The URL is normalized to a domain and matched against known apps. If no app is found, one is created and a connector is built automatically. …
