Python Google CustomerLicense "Not authorized to access the application ID" - python

I am trying to check if the user has installed my marketplace app
from oauth2client.client import SignedJwtAssertionCredentials
import json
from httplib2 import Http
from apiclient.discovery import build
fname = 'my-creds.json'
scope = [
'https://www.googleapis.com/auth/appsmarketplace.license'
]
applicationId='12345678'
customerId='mydomain.com'
json_key = json.load(open(fname))
credentials = SignedJwtAssertionCredentials(json_key['client_email'], json_key['private_key'], scope)
http_auth = credentials.authorize(Http())
appsmarket = build('appsmarket', 'v2', http=http_auth)
response = appsmarket.customerLicense().get(applicationId=applicationId, customerId=customerId).execute()
print response
I have created a service account in the same project as my app in Google console.
But I keep getting
googleapiclient.errors.HttpError: <HttpError 403 when requesting https://www.googleapis.com/appsmarket/v2/customerLicense/471879773528/ashish%40noodletools.com?alt=json returned "Not authorized to access the application ID">

Do you add service account to your domain's authorized API clients in security section?
Look at Delegating domain-wide authority to the service account here: https://developers.google.com/identity/protocols/OAuth2ServiceAccount
To delegate domain-wide authority to a service account, an administrator of the Google Apps domain must complete the following steps:
Go to your Google Apps domain’s Admin console.
Select Security from the list of controls. If you don't see Security listed, select More controls from the gray bar at the bottom of the page, then select Security from the list of controls. If you can't see the controls, make sure you're signed in as an administrator for the domain.
Select Show more and then Advanced settings from the list of options.
Select Manage API client access in the Authentication section.
In the Client Name field enter the service account's Client ID.
In the One or More API Scopes field enter the list of scopes that your application should be granted access to.
Click Authorize.
Your application now has the authority to make API calls as users in your domain (to "impersonate" users). When you prepare to make authorized API calls, you specify the user to impersonate.

Python script for google drive is redirecting to chrome authentication

I write a python script to upload file to google drive, but the script is redirecting to chrome for email user authentication.
is there any way to avoid redirecting to chrome for authentication.
I'm running on python 3.9.
here is my sample code:
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
gauth = GoogleAuth()
drive = GoogleDrive(gauth)
upload_file_list = ['myfile.pdf']
for upload_file in upload_file_list:
gfile = drive.CreateFile({'parents': [{'id': '1B8ttlQMRUkjbrscevfa1DablIayzObh2'}]})
# Read file and set it as the content of this instance.
gfile.SetContentFile(upload_file)
gfile.Upload() # Upload the file.
The behaviour you are reporting is totally normal with OAuth 2.0 and the official Google APIs library.
What #Tanaike said is a good solution. You could use a service account to access Google Drive files without granting consent every time the token expires. With service accounts there are 2 options to achieve that:
Share the file/folder with the email address of the service account.
Use domain-wide delegation of authority to allow the service account to impersonate any user in your domain. Requires a domain using Google Workspace or Cloud Identity and Super Admin access to configure domain-wide delegation.
General information on how to make API calls with domain-wide delegation is available on this page https://developers.google.com/identity/protocols/oauth2/service-account#authorizingrequests.
Here is a working code sample:
from google.oauth2 import service_account
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
# Scopes required by this endpoint
# https://developers.google.com/drive/api/v3/reference/permissions/list
SCOPES = ["https://www.googleapis.com/auth/drive.readonly"]
# Variable that holds the file ID
DOCUMENT_ID = "i0321LSy8mmkx_Bw-XlDyzQ_b3Ny9m74u"
# Service account Credential file downloaded with domain-wide delegation of authority
# or with shared access to the file.
SERVICE_ACCOUNT_FILE = "serviceaccount.json";
# Creation of the credentials
credentials = service_account.Credentials.from_service_account_file(
SERVICE_ACCOUNT_FILE,
scopes=SCOPES)
# [Impersonation] the service account will take action on behalf of the user,
# requires domain-wide delegation of authority.
delegated_credentials = credentials.with_subject('user#domain.com')
# The API call is attempted
try:
service = build('drive', 'v3', credentials=delegated_credentials)
# Retrieve the documents contents from the Docs service.
document = service.files().get(fileId=DOCUMENT_ID).execute()
print('The title of the document is: {}'.format(document.get('name')))
except HttpError as err:
print(err)
Keep in mind that to use user impersonation you will need to configure domain-wide delegation in the Admin console of the domain that has the files (this will also work for external files shared with users in the domain).
If you want to use this with regular consumer accounts you can't use user impersonation, instead you will share the file with the service account (read or write access) to later make API calls. Line 20 creates delegated credentials, this line needs to be removed if you will use this other approach.

Sending automated emails using Gmail API with Python and OAuth authentication

I have a Python code that was using SendGrid API to send emails, but now I want to migrate to Google in order to send business emails. It also runs in Docker containers.
I followed Gmail Python Quickstart in order to use Gmail API in my Python code and the problem is that when trying to send email, it shows an authorization link in Docker logs in order to get token, etc.
Is there a way to complete authorization in the background without any further interaction or use an API key just like SendGrid to programmatically authenticate your application?
I am a service provider and want to send emails such as reset password links, confirmation code, etc. automatically; the code is deployed on a Linux host. I have access to workspace account, and I already have verified my domain.
The tutorial you are following is designed for an installed application. Hence the InstalledAppFlow.
It states it at the top of the file.
Authorization credentials for a desktop application. To learn how to create credentials for a desktop application, refer to Create credentials.
This means when your code runs it is going to pop up the consent screen on the machine the code is running on, in this instance Docker.
flow = InstalledAppFlow.from_client_secrets_file(
'credentials.json', SCOPES)
You need to create it using a web application so that your users can consent to your application accessing their data and their Gmail account.
Automated send emails service account option.
You were not clear as who you are sending emails for. As you are using send grid, it implies to me this is some kind of automated system. Which would mean that you are trying to send emails on behalf of a Gmail account that you control.
In that case you would most often want to use a service account. Service accounts allow for server-to-server interaction between Google APIs. However, service accounts will only work with Gmail if this is a Google workspace Gmail account and you can set up domain-wide delegation.
There is an example in the documentation. Just change it to Gmail scopes. The key point is the create_delegated which must be a user on your domain.
from googleapiclient.discovery import build
from oauth2client.service_account import ServiceAccountCredentials
# Email of the Service Account
SERVICE_ACCOUNT_EMAIL = '<some-id>#developer.gserviceaccount.com'
# Path to the Service Account's Private Key file
SERVICE_ACCOUNT_PKCS12_FILE_PATH = '/path/to/<public_key_fingerprint>-privatekey.p12'
def create_directory_service(user_email):
"""Build and returns an Admin SDK Directory service object authorized with the service accounts
that act on behalf of the given user.
Arguments:
user_email: The email of the user. Needs permissions to access the Admin APIs.
Returns:
Admin SDK directory service object.
"""
credentials = ServiceAccountCredentials.from_p12_keyfile(
SERVICE_ACCOUNT_EMAIL,
SERVICE_ACCOUNT_PKCS12_FILE_PATH,
'notasecret',
scopes=['https://www.googleapis.com/auth/admin.directory.user'])
credentials = credentials.create_delegated(user_email)
return build('admin', 'directory_v1', credentials=credentials)
Standard Gmail solution
You can run your application once, and then when you place it in the Docker container, make sure that you include the token.json file that was created this is the file that contains the credentials that grant the application access to your account.
If you open it you will find an access token and a refresh token within. The refresh token will give your application the ability to request a new access token whenever it needs one.

GTasks API Service Account: Client is unauthorized to retrieve access tokens using this method

I have a service account with Domain wide delegation and its been working fine for Calendar APIs. I am able to impersonate as other users within the organization to CRUD events in Google Calendar without the Consent Screen. Now i'm trying to consume GTasks API but getting error.
For GTasks
credentials = service_account.Credentials.from_service_account_file('service-account.json', scopes=['https://www.googleapis.com/auth/tasks'])
delegated_credentials = credentials.with_subject('username#company.com')
service = build('tasks', 'v1', credentials=delegated_credentials)
tasklists = service.tasklists().list(maxResults=10).execute()
and got below error.
('unauthorized_client: Client is unauthorized to retrieve access tokens using this method, or client not authorized for any of the scopes requested.', '{\n "error": "unauthorized_client",\n "error_description": "Client is unauthorized to retrieve access tokens using this method, or client not authorized for any of the scopes requested."\n}')
For GCalendar, working fine
credentials = service_account.Credentials.from_service_account_file('service-account.json', scopes=['https://www.googleapis.com/auth/calendar'])
delegated_credentials = credentials.with_subject('username#company.com')
service = build('calendar', 'v3', credentials=delegated_credentials)
events = service.events().list(calendarId=SUBJECT,timeMin=now,maxResults=10,orderBy='startTime',singleEvents=True).execute()
I'm using this lib https://github.com/googleapis/google-api-python-client. Any hint what's wrong here?
Not all APIs support domain-wide delegation. If they do, you will see it mentioned in the Auth documentation.
The Calendar API supports domain-wide delegation, and the Tasks API does not.
https://developers.google.com/calendar/auth
https://developers.google.com/tasks/auth
Google Calendar and Tasks both support domain wide-delegation, I am using that. My suggestion is:
Check if your developer console has enabled Google Tasks API
Check if you've added Google Tasks into your API permission scope in your G Suite admin dashboard. May refer https://developers.google.com/identity/protocols/OAuth2ServiceAccount for more detail

Using Google People API with Service Account

I'm using the Google People API to access my contacts.
I activated it in the Google Developers Console and created a project, a service account (ending with ....iam.gserviceaccount.com) and a key for authentication which is stored in JSON format.
When I access the contacts, it seems to take the contacts of my service account address rather than my Google account which results in an empty list.
How can I tell the API to use my account rather than the service account?
This is the code I have so far:
from google.oauth2 import service_account
from googleapiclient.discovery import build
# pip install google-auth google-auth-httplib2 google-api-python-client
SCOPES = ['https://www.googleapis.com/auth/contacts.readonly']
KEY = '~/private.json'
credentials = service_account.Credentials.from_service_account_file(
KEY, scopes=SCOPES)
service = build(
serviceName='people', version='v1', credentials=credentials)
connections = service.people().connections().list(
resourceName='people/me', personFields='names').execute()
print(connections)
# result: {}
A service account is NOT you a service account is a dummy user it has its own google drive account, google calendar and apparently google contacts. The reason that you are seeing an empty result set is that you have not added any contacts to the service accounts account.
Service accounts are most often used to grant access to data that the developer owns. For example you can take the service account email address and share one of your folders on google drive it will then have acccess to that folder on your google drive account. You can do the same with google calendar.
There are some apis that do not give you the ablity to share your data with other users. Youtube, adwords, blogger and google contacts to name a few.
You cant use a service account to access your personal google contacts. Your best bet would be to authenticate your application with oauth2 and access them that way.
Note about Google Workspace
If you have a google workspace account, a serivce account can be configured to act on behalf of a user on the domain, but only a user on the domain. Perform Google Workspace domain-wide delegation of authority
Not a python expert but I've just performed the task the OP is talking about in .NET and I am pretty sure it's feasable with Python too.
So it looks like all needs to be done is delegating domain-wide authority to the SA. I.e. assign required scopes for your SA, in my case it was https://www.googleapis.com/auth/contacts.readonly.
Then you should do your call and specify an account you're trying to impersonate (took the python example from here)
from google.oauth2 import service_account
SCOPES = ['https://www.googleapis.com/auth/sqlservice.admin']
SERVICE_ACCOUNT_FILE = '/path/to/service.json'
credentials = service_account.Credentials.from_service_account_file(
SERVICE_ACCOUNT_FILE, scopes=SCOPES)
# this is the line you apparently were missing
delegated_credentials = credentials.with_subject('user#example.org')
Then you'll be able to do the people/me calls. Worked for me in .NET as I said.

Authorizing a python script to access the GData API without the OAuth2 user flow

I'm writing a small python script that will retrieve a list of my Google Contacts (using the Google Contacts API) and will randomly suggest one person for me to contact (good way to automate keeping in touch with friends!)
This is just a standalone script that I plan to schedule on a cron job. The problem is that Google seems to require OAuth2 style authentication, where the user (me) has to approve the access and then the app receives an authorization token I can then use to query the user's (my) contacts.
Since I'm only accessing my own data, is there a way to "pre-authorize" myself? Ideally I'd love to be able to retrieve some authorization token and then I'd run the script and pass that token as an environment variable
AUTH_TOKEN=12345 python my_script.py
That way it doesn't require user input/interaction to authorize it one time.
The implementation you're describing invokes the full "three-legged" OAuth handshake, which requires explicit user consent. If you don't need user consent, you can instead utilize "two-legged" OAuth via a Google service account, which is tied to an application, rather than a user. Once you've granted permission to your service account to access your contacts, you can use the oauth2client ServiceAccountCredentials class to directly access GData without requiring user consent.
Here's the two-legged authentication example from the Google service account documentation:
import json
from httplib2 import Http
from oauth2client.service_account import ServiceAccountCredentials
from apiclient.discovery import build
scopes = ['https://www.googleapis.com/auth/sqlservice.admin']
credentials = ServiceAccountCredentials.from_json_keyfile_name(
'service-account.json', scopes)
sqladmin = build('sqladmin', 'v1beta3', credentials=credentials)
response = sqladmin.instances().list(project='examinable-example-123').execute()
print response
