The easiest is to export the variable REQUESTS_CA_BUNDLE that points to your private certificate authority, or a specific certificate bundle. On the command line you can do that as follows:
export REQUESTS_CA_BUNDLE=/path/to/your/certificate.pem
python script.py
If you have your certificate authority and you don't want to type the export each time you can add the REQUESTS_CA_BUNDLE to your ~/.bash_profile as follows:
echo "export REQUESTS_CA_BUNDLE=/path/to/your/certificate.pem" >> ~/.bash_profile ; source ~/.bash_profile

Self-signed ssl certs verification - Python Help - Discussions on Python.org
March 19, 2025 - I’ve generated a private key and a self-signed certificate 3 different ways: using command-line openssl, pyopenssl and pyca/cryptography. Then I’ve used them to create ssl context for a simple flask app. The flask app itself runs fine, but when I try to send a file to it using requests.post(url, files={"file": my_file}, verify=my_cert), I get an ssl error: SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate (_ssl.c:1007)')) ...
Python Requests and self-signed SSL certs
requests uses urlllib3, which passes None by default to ssl.wrap_socket. The default is set by create_default_context which calls load_default_certs which calls set_default_verify_paths which has the following documentation:
Load a set of default “certification authority” (CA) certificates from a filesystem path defined when building the OpenSSL library. Unfortunately, there’s no easy way to know whether this method succeeds: no error is returned if no certificates are to be found. When the OpenSSL library is provided as part of the operating system, though, it is likely to be configured properly.
In conclusion, I have no idea.

r/learnpython on Reddit: Python Requests and self-signed SSL certs
July 8, 2015 -
I am working on talking to my server via https with Python Requests. I have a self signed cert on the box the client is running on. When i do the following
r = requests.request(http_method, http_url, data=payload, headers=kwargs['headers'], verify='/etc/ssl/certs/mycert.pem')
Everything works perfect! YAY!!! BUT, I do not want to have to provide a path to verify, as this program will be talking from multiple clients to multiple servers. So it has to be dynamic. I have installed the self-signed cert on my box using ca-certificates. I can view the certificate in /etc/ssl/certs/ no problem. I can run openssl to dump the cert and it's fine. I can provide the path as shown above and it works. How can I tell requests to look at and honor the trusted certs on my box?

How to Fix “SSL: CERTIFICATE_VERIFY_FAILED” in Python Requests - DEV Community
September 15, 2025 - One scenario worth adding that trips up a lot of enterprise devs: when verify=False works but specifying verify=certifi.where() still fails, it's almost always a corporate SSL inspection proxy - the firewall is decrypting and re-signing your HTTPS traffic with an internal CA cert that certifi doesn't include. The fix is to get that root cert from your IT team (.crt or .pem) and pass it via: requests.get(url, verify="/path/to/corp-root-ca.pem") or set REQUESTS_CA_BUNDLE as a global env var so you don't have to patch every script. Also worth noting for anyone on Python 3.13 - self-signed certs that worked fine in 3.9/3.10 can now fail because the chain validation is stricter.

If you know what you are doing and fine with disabling SSL verification, here is a solution that works.
client = OpenAI(
api_key=openai_api_key,
base_url=openai_api_base,
http_client = httpx.Client(verify=False)
)
