Thanks to this guy, whose question and gist helps me understand the google api and requests for it to get access for google drive.

I found everything!

If anybody will be confused like me:
Get your google drive your_api_key from here:

• https://console.developers.google.com/apis/credentials?project=[your_project]

in section with name “API keys” – or you can generate it by pushing “New Credentials” -> “API key”

Also you can get your token with google “quick start” even for python3:

• https://developers.google.com/drive/v2/web/quickstart/python

Your token will be saved on system user’s folder (C:/Users/user/.credentials) or (/root/.credentials) for Linux if you run it under “root”. The token is in “access_token” key value.

Then you can generate request, but at first check this: http://docs.python-requests.org/en/master/user/quickstart/#custom-headers

And this is working example to get list of your google drive files:

import requests

token = '<THAT_TOKEN_FROM_YOUR_FILE_FROM_USERS_DIR>'
url = "https://www.googleapis.com/drive/v2/files?key="
key = "<THAT_KEY_WHICH_YOU_GENERATE_ON_GOOGLE_API_CONSOLE>"
header = {'Authorization':"Bearer " + token}
list_files = requests.get(url+key, headers=header)
answer = list_files.json()
print(answer)

Attention!

Token is expiring very soon!

Curl example from docs:

Examples

A call to the drive.files endpoint (the Drive API) using the access_token query string parameter might look like the following, though you’ll need to specify your own access token:

GET https://www.googleapis.com/drive/v2/files?access_token=1/fFBGRNJru1FQd44AzqT3Zg

Here is a call to the same API for the authenticated user (me) using the Authorization: Bearer HTTP header:

GET /drive/v2/files HTTP/1.1
Authorization: Bearer 1/fFBGRNJru1FQd44AzqT3Zg
Host: googleapis.com

You can try out with the curl command-line application. Here’s an example using the HTTP header option (preferred):

curl -H "Authorization: Bearer 1/fFBGRNJru1FQd44AzqT3Zg" https://www.googleapis.com/drive/v2/files

Or, alternatively, the query string parameter option:

curl https://www.googleapis.com/drive/v2/files?access_token=1/fFBGRNJru1FQd44AzqT3Zg
