Youtube API - Upload to known accounts?

Question

I am looking for a way to upload videos from a web service to a handful of known Youtube accounts where I am the owner (have login/pw credentials).

For instance, when a video is uploaded to this site, it should also upload to Youtube accounts A, B, and C via the API.

It seems that Youtube has an old method for authenticating accounts in this manner called ClientLogin, but it has been deprecated as of 2012 and in fact no longer works consistently (significant problems popping up as of April 2013). (ClientLogin Docs)

The new recommended protocol is oAuth 2.0 (docs), but I am struggling to understand - is this workflow possible via oAuth authentication? If not, is there an alternative that could handle it?

If you have a CMS account managing those account, you can do.

Currently service accounts are not working with Data API v3, hope to have them back soon.

Instead of storing login/pw credentials you must store login/refresh-token. With the refresh-token you request a new access-token after the current one has expired (after 1 hour)

The main difference is for the first time, you have to ask user to give you authorization via browser.

You can store the tokens and while you are calling the APi method, you can set the token in call to upload to that user's account
