invalid client error from YouTube Analytics API

Original

I am trying to get top 10 videos in my channel from YouTube, so I followed the sample code from Google: https://developers.google.com/youtube/analytics/v1/code_samples/python#retrieve_top_10_videos_by_viewcount

I have installed all packages and downloaded client secrets. I typed python get_json.py in command line. (The sample script is renamed to get_json.py) This is what is showing up in command line:

WARNING:root:This function, oauth2client.tools.run(), and the use of the gflags library are deprecated and will be removed in a future version of the library.
Your browser has been opened to visit:

https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyoutube.readonly+https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fyt-analytics.readonly&
redirect_uri=http%3A%2F%2Flocalhost%3A8080%2F&response_type=code&client_id=849986408789-otj3v9ghdlrr24nag9c4bepei6fo0vvm.apps.googleusercontent.com&access_type=offline

If your browser is on a different machine then exit and re-run this application with the command-line parameter

--noauth_local_webserver

Then my browser pops up and I am getting this invalid_client error. Did I miss anything?

Update

I added a name in "product name" in Google API Console and reset my client secret. It works now.

It seems like you set your credentials in Google Developer Console wrong. If you are running it from a local machine, you should pick "installed application" or if from a webserver, you should specify the redirect_uri.

Also make sure YT Analytics API is turned on in the console for this project.
