Trouble importing SignedJwtAssertionCredentials in Google Drive API

Hey everyone, I’m stuck with a Google Drive API authentication issue. I’m trying to set up domain-level OAuth2 for the API, but I’m hitting a roadblock.

I’ve got OpenSSL installed, but when I try to import SignedJwtAssertionCredentials, I get this error:

ImportError: cannot import name SignedJwtAssertionCredentials

Here’s a snippet of what I’m trying to do:

from oauth2client.client import GoogleCredentials

def get_drive_service():
    credentials = GoogleCredentials.get_application_default()
    return build('drive', 'v3', credentials=credentials)

# This is where it fails
from oauth2client.client import SignedJwtAssertionCredentials

I’m pretty sure I’m following the docs correctly, but something’s not clicking. Any ideas what might be causing this? Maybe I’m missing a dependency or using an outdated version of something?

Really appreciate any help you can give me on this one!

I’ve dealt with this exact problem before, and it can be frustrating. The issue is that SignedJwtAssertionCredentials has been phased out in newer versions of the oauth2client library. Here’s what worked for me:

First, make sure you’re using the google-auth library instead of oauth2client. Then, you can use service account credentials like this:

from google.oauth2 import service_account
from googleapiclient.discovery import build

credentials = service_account.Credentials.from_service_account_file(
‘path/to/your/service-account-file.json’,
scopes=[‘https://www.googleapis.com/auth/drive’]
)

service = build(‘drive’, ‘v3’, credentials=credentials)

This approach is more current and should resolve the import error you’re seeing. Just remember to replace the file path with your actual service account key file. Let me know if you run into any other issues!

hey alex, i ran into this issue b4. SignedJwtAssertionCredentials is deprecated. try using service_account.Credentials.from_service_account_file() instead. it worked for me. make sure ur using the latest google-auth library too. hope this helps!

I’ve encountered this issue in my projects as well. The SignedJwtAssertionCredentials class has been deprecated, which explains the import error. A current solution is to use service account credentials instead. In my experience, installing the latest google-auth and google-auth-oauthlib packages and using the service_account module from google.oauth2 delivers a more dependable outcome. For example, you can import service_account and build your drive service as shown below:

from google.oauth2 import service_account
from googleapiclient.discovery import build

credentials = service_account.Credentials.from_service_account_file(
‘path/to/your/service_account_key.json’,
scopes=[‘https://www.googleapis.com/auth/drive’]
)

drive_service = build(‘drive’, ‘v3’, credentials=credentials)

Ensure that you reference the correct file path. This method should resolve your import error and get your API integration working.
