Get post URL to help with vimeo embed

Im working on a Vimeo intergration and wanting to setup auto embeding based on the ghost URL.

In short Zapier auto posts to Ghost from Vimeo. And I can use the vimeo video ID: “474656070” as the ghost post url/slug. The vimeo ID and the Ghost URL will always be indentical.

How would i modify the theme to add the below embed code, BUT also includig the ghost url. Which would also be “474656070” all going well. Into the header of each post? replacing the featured image.

Thanks in advance
