Goroutines communicate data via channels, so you can just pass a channel a message (which can be anything). The channel will sit and wait for a message, processing the message when it's received. That said, for anything like a website or an API you probably won't need to worry much about channels or concurrency at all. The stdlib handles each web request on a different goroutine, so you write synchronous code, yet your server is concurrent.
