Can a WordPress website embed Shopify functionality?

I currently have a website built in WordPress, but would like to be able to embed Shopify's product pages or checkout functionality directly into the site so that users can complete their purchase without having to jump through hoops. Is there any reliable way to accomplish this? For example, through Shopify's Buy Button, embed code, or a plugin? Has anyone tried this combination? Is it smooth in terms of experience and payment process?
I'd like to hear advice from experienced folks, thanks!
