I can't authorize gmail api application in google colaboratory

why is it redirected to localhost?
There is a simple way to send e-mail at google colab? with or without using gmail?
i'm using the google colab at opera browser.
Can anyone help me how i can send a simple e-mail at google colab without lowing the gmail security level?

There is something wrong with the way you are loading the run_local_server if you are getting a 404 error.
The code below is my standard QuickStart for People api. I just tested it and it works fine. I am not getting a 404 error.

if you know some guide or complete tutorial to Automate Document Creation with the Google Docs API like invoices and replace encapsulation values like {{productID}} I will be very grateful
I saw the Automate document creation of google channel but it wasn't very helpful https://youtu.be/-dX-fWb3ogE
Best Regards

Make sure you also enable the Docs API in your Developers Console.
Delete the credential file ~/.credentials.json and token.json (if you ran the code before
Change the scope variable used for reading docs
var SCOPES = ['https://www.googleapis.com/auth/documents.readonly'];
to
var SCOPES = ['https://www.googleapis.com/auth/documents'];
Check more info on https://developers.google.com/docs/api/reference/rest/v1/documents/create#authorization-scopes and https://developers.google.com/docs/api/how-tos/authorizing
After the execution of code, API will authenticate again and then the issue should be resolved.

I can't authorize gmail api application in google colab

else:
print('Labels:')
for label in labels:
print(label['name'])

after I click the authoritize steps, it pops out
it can't find the local host.
I have no idea what to do, and this quickstart can run successful in jupyter.

Google Api + List members of a group with python

Well, basicaly I'm lost with this task. I need to get all members of a group with the api google privedes. I'm starting with gmail quickstart example, first I have configure Api project and the OAuth client.
My first test was to see all the messages I have in my inbox, all ok. But to do the same with groups members I'm lost, I can't find the way to do it.
Any idea?
from __future__ import print_function
from googleapiclient.discovery import build
from httplib2 import Http
from oauth2client import file, client, tools
import json
import requests
SCOPES = 'https://www.googleapis.com/auth/admin.directory.group.member'
def main():
store = file.Storage('token.json')
creds = store.get()
if not creds or creds.invalid:
flow = client.flow_from_clientsecrets('credentials.json', SCOPES)
creds = tools.run_flow(flow, store)
service = build('gmail', 'v1', http=creds.authorize(Http()))
response = requests.get("https://www.googleapis.com/admin/directory/v1/groups/example#test.com/members")
print(response)
The response is a:
<Response [401]>

Looks like you started with the gmail example and then modified to access the admin/group function
Check the admin docs here https://developers.google.com/admin-sdk/directory/v1/quickstart/python

here is the function, it will retrieve all groups email addressess
def retrieving_groups():
response_group = service.groups().list(customer='my_customer').execute()
for group in response_group['groups']:
print(group['email'])

How to get the email-address of the sender of an email using Gmail Python API

Using the Google API python client, I want to find the email address/ name of the sender of an email.
So far, I have extracted details about the message but I am having trouble finding a way to extract the finder's information.
Here is the code snippet:
from __future__ import print_function
import httplib2
import os
from apiclient import discovery
from oauth2client import client
from oauth2client import tools
from oauth2client.file import Storage
try:
import argparse
flags = argparse.ArgumentParser(parents=[tools.argparser]).parse_args()
except ImportError:
flags = None
# If modifying these scopes, delete your previously saved credentials
# at ~/.credentials/gmail-python-quickstart.json
SCOPES = 'https://www.googleapis.com/auth/gmail.readonly'
CLIENT_SECRET_FILE = 'client_secret.json'
APPLICATION_NAME = 'Gmail API Python Quickstart'
def get_credentials():
"""Gets valid user credentials from storage.
If nothing has been stored, or if the stored credentials are invalid,
the OAuth2 flow is completed to obtain the new credentials.
Returns:
Credentials, the obtained credential.
"""
home_dir = os.path.expanduser('~')
credential_dir = os.path.join(home_dir, '.credentials')
if not os.path.exists(credential_dir):
os.makedirs(credential_dir)
credential_path = os.path.join(credential_dir,
'gmail-python-quickstart.json')
store = Storage(credential_path)
credentials = store.get()
if not credentials or credentials.invalid:
flow = client.flow_from_clientsecrets(CLIENT_SECRET_FILE, SCOPES)
flow.user_agent = APPLICATION_NAME
if flags:
credentials = tools.run_flow(flow, store, flags)
else: # Needed only for compatibility with Python 2.6
credentials = tools.run(flow, store)
print('Storing credentials to ' + credential_path)
return credentials
def main():
"""Shows basic usage of the Gmail API.
Creates a Gmail API service object and outputs a list of label names
of the user's Gmail account.
"""
credentials = get_credentials()
http = credentials.authorize(httplib2.Http())
service = discovery.build('gmail', 'v1', http=http)
results = service.users().messages().list(userId='me').execute()
messages = results['messages']
mail = service.users().messages().get(userId='me', id=messages[0]['id'], format='minimal').execute()
# I have other formats(RAW, METADATA and FULL) but I cannot parse them.
print(mail)
if __name__ == '__main__':
main()
I am looking for some method(either built-in or third-party library) to parse the email object returned by the API to return a more readable information. Some ad-hoc method will also work for the time-being.

I got an ad-hoc way to extract the basic information about an email.
Here is the snippet:
metadata = mail['payload']['headers']
# This list contains information about To, From and Subject among other gibberish.
for d in metadata:
# for sender's information
if d['name'] == 'From':
print(d['value'])
# for subject of the mail
if d['name'] == 'Subject':
print(d['value'])
