Youtube : we have made your content private - spam, deceptive practices and scams policy

When uploading the youtube video via Youtube API(Python), youtube makes the video private, whereas when I upload the same video via youtube.com, there is no error and video is uploaded successfully.
Could anyone please explain what could be the possible error.

As stated at the top of the page for Video.insert
All videos uploaded via the videos.insert endpoint from unverified API projects created after 28 July 2020 will be restricted to private viewing mode. To lift this restriction, each API project must undergo an audit to verify compliance with the Terms of Service. Please see the API Revision History for more details.
You need to apply for an audit of your application. Once you have passed the audit you will then be able to upload video's that are public.

according to this issue on github , you need to verify your account to upload public videos using apis.

ERROR 409: Requested entity already exists

I am using the sample code in this site https://developers.google.com/youtube/reporting/v1/reference/rest/v1/reportTypes/list
After setting-up successfully libraries and importing CLIENT_SECRETS_FILE into the code. When I run the code. It returned
Report type id: playlist_playback_location_a1
name: Playlist playback locations
Report type id: playlist_province_a1
name: Playlist province
Report type id: playlist_traffic_source_a1

I want to get playlist users in playlist_basic_a1 table so I entered the reportTypeId for the job: playlist_basic_a1
and set a name for the job: Playlist user activity

Why I got this error? And how to fix this error

I just tested your code and... It's working completely fine.
The job name must be unique for within a reportTypeId, so that error means that you used the name Playlist user activity for another job of the same type already.
That is not clear in the documentation. You can open an issue about the docs on their issue tracker here

Youtube Data API keeps asking for authorization

I am trying to make a simple python program which uses the Youtube Data API to retrieve results based on Youtube search queries.
I have created my OAuth credentials and have a client_secrets JSON. Everytime I run my python program it keeps asking me to get an authorization key so I can make the query. I have to open chrome and travel to the URL the API gives to me and log into my Google account and paste the key.
Can someone demonstrate how I can go about making this process automatic? I have read online and on stackoverflow that I would need a refresh token, or somehow store one so that it does not prompt me to authorize each time.
My code (copied from https://developers.google.com/youtube/v3/docs/search/list):

I just run into the same problem. After searching through the "YouTube Data Api v3" documentation I found this:
If you are using the installed app flow, authorization credentials are not stored in this sample code, so subsequent executions will prompt for reauthorization.
So I guess you should instead use the "Web Server App" flow. There's no way around this.

Try this 😎
def get_authenticated_service():
try:
credentials = google.oauth2.credentials.Credentials.from_authorized_user_file(CLIENT_SECRETS_FILE)
except ValueError as e: # first run with new secret.json
flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRETS_FILE, SCOPES)
credentials = flow.run_console()
with open(CLIENT_SECRETS_FILE, 'w') as file:
file.write(credentials.to_json())
return build(API_SERVICE_NAME, API_VERSION, credentials=credentials)

i want to download file from google drive using Drive Api

in this code :
file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M'
request = drive_service.files().get_media(fileId=file_id)
fh = io.BytesIO()
downloader = MediaIoBaseDownload(fh, request)
done = False
while done is False:
status, done = downloader.next_chunk()
print "Download %d%%." % int(status.progress() * 100)
I don't know how to get file_id , I was getting file_id while uploading but now I am not able to figure out how to get file_id of the file which is present on Google Drive.
Ex. if my uploaded file has name A001002.pdf , how can i get file id for this file.
there is some reference online which i am not able to understand.
link: files.list
any help?

The file.list method contains a q paramater which is used for searching
GET https://www.googleapis.com/drive/v3/files?q=name+%3D+'hello'&key={YOUR_API_KEY}

SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'

creds = store.get()
if not creds or creds.invalid:

items = results.get('files', [])
if not items:
print('No files found.')
else:
print('Files:')
for item in items:
print('{0} ({1})'.format(item['name'], item['id']))
Note this example does not show how to add the additional parameter i am still Googling that but i am not a python dev you may know more about how to do that than me.

Depending on your implementation, there is one more alternative. In case you do not need to programmatically get the fileID you can just open the file in google docs from the browser and the ID is shown in the URL.

i changed the redirect uri in my client json file but its not working
My questions are:
How to use existing browser for authentication url
Where to change the redirect URL
apiclient and oauth2client two apps are used in this API code
Please suggest any idea to solve this problem

You can change the redirect URL from Google Developer Console.
