c# - YouTube API "Queries per day" exceed in about 3 hours

Question

I created a program that uploads videos to YouTube using the YouTube Data API.

My program's flow is:

1. Login google account in google page using the URL https://accounts.google.com/o/oauth2/v2/auth?access_type=offline&prompt=consent&include_granted_scopes=true&client_id={YouTubeAppId}&redirect_uri={RedirectURL}&response_type=code&scope={Uri.EscapeDataString(https://www.googleapis.com/auth/youtube.readonly https://www.googleapis.com/auth/youtube.upload https://www.googleapis.com/auth/youtube.force-ssl https://www.googleapis.com/auth/userinfo.profile)}
2. Exchange code to access token: POST https://oauth2.googleapis.com/token
3. Get user's channel's IDs: GET https://youtube.googleapis.com/youtube/v3/channels?part=snippet,statistics&mine=true&access_token={AccessToken}. Then I select the video and split it to 1Mb chunks.
4. Get upload URL: POST https://www.googleapis.com/upload/youtube/v3/videos?uploadType=resumable&part=snippet,status,contentDetails&access_token={token} with model
5. Send chunks of video using URL from Location header in previous step.

Also I've got 10min timer which refreshes access token.

foreach (SocialLogin item in logins.Where(x => (x.UpdatedOn.AddSeconds(x.ExpirationSeconds) - DateTime.Now).TotalSeconds < 600))
        {
            SocialLogin youModel = await _youtubeService.RefreshTokenAsync(item);
            youModel.UpdatedOn = DateTimeOffset.Now;
            youModel.ExpirationSeconds = 3600;
            await _loginRepository.UpdateAsync(youModel);
        }

This function gets all YouTube logins from the database and refreshes tokens for those logins that expire less than 10 minutes using POST on the URL https://oauth2.googleapis.com/token. I uploaded couple of 15mb videos and it works well, but after it Queries per day quota counted about 2500 queries. I added breakpoints for all methods which make API calls and counted them all. There was about 50 requests at all. After couple of hours I sent another 2 30mb videos and this quota had about 8000 queries. How is this quota calculated? And what does it calculate? Now it's 0 but yesterday it was 8120.

Answer 1

First, you'll have to acknowledge that the YouTube Data API does not account the amount of megabytes of video content the you're uploading via its Videos.insert endpoint.

Then you'll have to acknowledge that the API is not accounting for the number of endpoint calls.

Given that each endpoint has attached a quota cost, the YouTube Data API is accounting for the sum of units of quota cost of all endpoint calls you make on a particular day.

For example, having a daily quota allocation of 10000 units, since the cost of one video upload is 1600 units, you're allowed to upload at most 6 videos, irrespective of their actual size (if not considering the cost of other API calls that you made).
