Sendgrid-python: python_http_client.exceptions.UnauthorizedError: HTTP Error 401: Unauthorized

[JohnnyQQQ]

I've gone through nearly everything on the help pages here but I'm still getting an HTTP Error 401: Unauthorized error.

I have created about 4 new api's and different configurations but still the same error

This is a new account and was hoping to use sendgrid for email.

I've done the curl examples and everything runs fine.

The code is directly from sendgrid:

import sendgrid
import os
from sendgrid.helpers.mail import *

SENDGRID_API_KEY = 'sendgridapi*'

sg = sendgrid.SendGridAPIClient(apikey=os.environ.get(SENDGRID_API_KEY))
from_email = Email("[email protected]")
to_email = Email("[email protected]")
subject = "Sending with SendGrid is Fun"
content = Content("text/plain", "and easy to do anywhere, even with Python")
mail = Mail(from_email, subject, to_email, content)
response = sg.client.mail.send.post(request_body=mail.get())
print(response.status_code)
print(response.body)
print(response.headers)

Hello @JohnnyQQQ,

This line: SENDGRID_API_KEY = '***sendgrid***api***' is not necessary. Your API Key should have been set in your environment like so: https://github.com/sendgrid/sendgrid-python#setup-environment-variables

The method os.environ.get gets the API key from the envoronment variable SENDGRID_API_KEY, but you have set SENDGRID_API_KEY directly. So when os.environ.get attempts to read the SENDGRID_API_KEY environment variable, it is empty, causing your API key to be blank and thus the 401 error.

With Best Regards,

Elmer

Thanks, I'm also on a windows system so I'll have to set up the path.

Just update your code to use the one you want if you prefer not to use environment variable

SENDGRID_API_KEY = '***sendgrid***api***'

sg = sendgrid.SendGridAPIClient(apikey=SENDGRID_API_KEY )

[JohnnyQQQ]

For some reason that didn't work, but once I set the environment variable it worked

I'm getting this 401 Unauthorized exception. i did this environment stuff. I'm not able to debug this exception. In local it's working, when deployed in nginx+gunicorn that time i'm getting this exception.

[JairusLopes]

Hello,
I created the environment variable, with export.
And it worked.

Hello @sakthips,

I suggest that you check the value of your SendGrid API Key in your deployed environment. I'm guessing the key is not getting set properly in the deployed environment.

With Best Regards,

Elmer

how to fix it

[childish-sambino]

@Coder0111 Please post some sample code that illustrates the issue. Are you reading the API key from an env var? If so, could you try logging the value to help debug if it's being set properly?

[Coder0111]

@childish-sambino my sendgrid details are correct though iam getting this may u help me for this

[Coder0111]

bro i did they relied me this as u can see in screen shot

[Coder0111]

is there another service in your mind who provide emailing api for free

[arycloud]

There's another solution works for me to overcome HTTP Error 401: Unauthorized. You can use dotenv package instead. Here are the steps:

1. cd ~/my-project-dir
2. echo "export SENDGRID_API_KEY=YOUR_KEY" >> .env
3. pip install python-dotenv in your virtualenv
4. echo python-dotenv >> requirements.txt
5. Add this to your WSGI file:

from dotenv import load_dotenv
project_folder = os.path.expanduser('~/my-project-dir')  # adjust as appropriate
load_dotenv(os.path.join(project_folder, '.env'))

1. Access your key as: SECRET_KEY = os.getenv("SECRET_KEY")
