Exception/Log

HTTP Error 403: Forbidden

Technical details:

• sendgrid-python version: 6.2
• python version: 3.6.8

I am also running into this.

• python version: 3.5.9
• sendgrid-python version: 6.2.2

Though the example above doesn't seem to actually include the api key, but I did, via:

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

@mmoomocow Recommend upgrading to a later release of this library. I'm not even seeing a 3.2.7 version.

@jaimemarijke Are you seeing this 403 when performing the same mail send operation?

[jaimemarijke]

@childish-sambino Yes, I got the 403 after following these instructions: https://app.sendgrid.com/guide/integrate/langs/python

I use pyenv to set the python version in my repo, and tox to create a python virtual environment (py35)

I had the same issue until I finally got a user email registered. So you might need to check to see if the domain or sender email is validate on the dashboard.

I also used the without helper class example.

Good luck.

[childish-sambino]

+1 to @devsetgo's comment. @jaimemarijke Let me know if that doesn't resolve it for you.

[childish-sambino]

Also, try changing the exception logic to log the response body for more details:

print(e)
print(e.body)

Hi there folks, I'm facing the same issue. I'm getting 403 forbidden error when I try to send my first e-mail. I already checked my e-mail. How do I check my account on dashboard? Or is it the same thing? @childish-sambino @devsetgo

[childish-sambino]

@thiagolara Have you tried logging the response body for additional error details?

[thiagolara]

Hey @childish-sambino , yes I just did it and I got this message:

b'{"errors":[{"message":"The from address does not match a verified Sender Identity. Mail cannot be sent until this error is resolved. Visit https://sendgrid.com/docs/for-developers/sending-email/sender-identity/ to see the Sender Identity requirements","field":"from","help":null}]}'

I was using my customer's email as sender in a contact form.

I solved the problem changing the "from email" (sender email) to my own account email, instead of using my customer's email :)

As we can see on the link above, they changed it April 6, 2020.

Thank you !

I solve the issue by verifying the from_email (which is also sender email) address from the dashboard.

You might need to do a Sender Identity verification. Checkout this page:
