They have a great development team over at Channels and a transparent API that should make integration similar to Plex.
The following is a list of resources you can query. Read more below on their data structures and the API endpoints available for querying them.

For those unfamiliar with the software, it is similar to plex with the ability to create custom Virtual TV channels for integration into the tv guide alongside steaming services that support TV Anywhere like YoutubeTV, Philo, PlutoTV, etc. This makes it a better replacement for traditional cable TV IMO.
I have attached an example of custom made virtual channels to hopefully get people excited about a possible integration. Example virtual channels using your own local content: A Kids Movies channel that plays kids movies 24/7. Or the Lego Channel that shows just Lego TV Shows and Movies. A Monster TV Channel for Halloween that shows movies featuring werewolves, vampires, mummies, etc.
You get the idea.
