Amazon s3 policy grants access only to Vimeo api

Question

Is it possible to grant access, via a policy, only to Vimeo api to download the private content into my bucket?

I am trying to create a videos platform with RoR 5 and I am using paperclip to upload the videos to my S3 account. To avoid incompatibility problems with the videos I want use Vimeo to transcode and hosting them (I think is a better option than the transcoding service in cloud).

So I have to use the Vimeo API to upload the videos to my Vimeo account and more specifically the option "Automatic (“pull”) uploads"

• Developer / API Upload Videos

where I need to pass "A url to a video file accessible by Vimeo's servers.", a S3 url in my case. The problem is that I want to have private content in my S3 bucket, but so the vimeo API can't access to the video url.

Answer 1

According to AWS S3 documentation, this is possible. Follow this link for details: Restricting Access to a Specific HTTP Referrer . However, I am not sure that api.vimeo.com is the name of the Vimeo server that pulls videos.
