HTTP Error 401:Unauthorized with Cronjob

[asing012]

Hey guys! I am getting the HTTP Error 401. It works fine when I directly run the code. But I am trying to automate it using cronjob on Ubuntu and it keeps giving me this error. I have also tested my API key by sending a request to "https://sendgrid.com/docs/for-developers/sending-email/curl-examples/#-Hello-World".

Any help would be appreciated!

I looked at your repo, this doesn't look like an issue with sendgrid, more your code.

_SendGridAPIClient(os.environ.get('$SENDGRID_APIKEY'))

you're getting your apikey from your environment, your cron user probably doesn't have the same as your normal user.

@kalkaran thanks for your comment. I did check the cron user, it has the same environment variable. Do you think adding the API Key instead of the environment variable will work?

[kalkaran]

Have you considered setting up a txt file and having the variables you pass (api key, message,...) output into it, and having it triggered by cron? That should show what you don't have access to.

Personally I got round this issue but setting up a screen environment and leaving my python script running in it.

Hi @asing012,

It looks like you might be grabbing your SENDGRID_API_KEY environment variable incorrectly. Note that the correct way to initialize your SendGridAPIClient object is:

sg = SendGridAPIClient(os.environ.get('SENDGRID_API_KEY'))

It's a subtle difference, but your code was looking for an environment variable called $SENDGRID_API_KEY instead of SENDGRID_API_KEY.

@eshanholtz thank you for the comment. It is working now.

If you have this problem but your API is valid, it might be that your IP is not correctly whitelisted
