Dev Help Wanted! Webhook to log time spent watching to Timeular

I could really use the help of a developer. I really want a way to keep track of the time I spend watching movies and TV Shows on Plex, and log this time in Timeular. They have an API documented here: https://developers.timeular.com/

What I want is for tracking to be started when you press play on a Movie or a TV Show, and stopped when you pause or stop playback.

Not being a developer I’m not sure how complicated this would be to implement but I wonder whether it could be done using a webhook?

Could anyone let me know if this is possible?
