I am trying to understand how etag works with the Youtube API. Here is the request I am making:

curl -X GET \
  'https://www.googleapis.com/youtube/v3/channels?part=statistics&fields=items&id=UCmRtPmgnQ04CMUpSUqPfhxQ' \
  -H 'Authorization: Bearer dezferfnr....' \
  -H 'Cache-Control: no-cache' \
  -H 'If-None-Match: \"g7k5f8kvn67Bsl8L-Bum53neIr4/4ygpLCFz2IoIJNkG3XO1Pys1hck\"'

And here is the response I am getting:

{
    "items": [
        {
            "kind": "youtube#channel",
            "etag": "\"g7k5f8kvn67Bsl8L-Bum53neIr4/4ygpLCFz2IoIJNkG3XO1Pys1hck\"",
            "id": "UCmRtPmgnQ04CMUpSUqPfhxQ",
            "statistics": {
                "viewCount": "4757859",
                "commentCount": "63",
                "subscriberCount": "68151",
                "hiddenSubscriberCount": false,
                "videoCount": "898"
            }
        }
    ]
}

As you can see, the etag found in the response is the same as the one I sent in the request's header, and I can't understand why I am not getting an HTTP 304 response (Not Modified) instead.

Try removing escaped double quotes from the beginning and the end of etag (leave the unescaped ones because they are part of etag):

curl -X GET \
    'https://www.googleapis.com/youtube/v3/channels?part=statistics&fields=items&id=UCmRtPmgnQ04CMUpSUqPfhxQ' \
    -H 'Authorization: Bearer dezferfnr....' \
    -H 'Cache-Control: no-cache' \
    -H 'If-None-Match: "g7k5f8kvn67Bsl8L-Bum53neIr4/4ygpLCFz2IoIJNkG3XO1Pys1hck"'

(use curl -i -X GET... to see the headers of response in CLI, you'll see 304 Status, otherwise it would just be empty string).
