Link on Office Guy page is broken – 404

ON this page,
there is a link to
https://www.myofficeguy.com/developers/woocommerce/.

that is supposed to explain how to integrate with the API with Office Guy. The link is broken, with a 404 error.
I also don’t see any mention of WordPress on the Office Guy site.

Is there another way to learn about to install the plugin and work it?

Thanks,
Daniel
