Python certificate verify failed

[mkreder]

Hi,

I got the sample python code from the API doc page. I am trying this code which is in the README.md

config.username = 'IJE1SG1HLQL1T5AKRDI721IQli.................'
config.password = 'CXx6XSnm76A........
config.cert_file = 'PATH/cert.pem' # this file is the one I downloaded in the Credentials page next to my user credential
config.key_file = 'PATH//key.pem' # this file is the one it ask me to download when I created the project
config.ssl_ca_cert = 'PATH/ca.crt' # this file is one of the "common files". I tried the Digicert CA file and the VDPCA files and none of them worked.

When I try to run the python code I am getting this error if I use the VDPCA cert:

2019-01-17 17:56:05,882 WARNING Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, u'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:726)'),)': /visadirect/fundstransfer/v1/multipullfundstransactions/status_identifier_example

And this error if I use the Digicert CA cert:

2019-01-17 18:31:33,416 WARNING Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(0, u'unknown error (_ssl.c:3027)'),)': /visadirect/fundstransfer/v1/multipullfundstransactions/status_identifier_example

I am not sure what I am doing wrong.

I got it working by switch the CA certificate to a plain text .pem  file

I am still facing the problem even after trying what you have mentioned..

import requests

user_id = 'IJE1SG1HLQL1T5AKRDI721IQli.................'
password = 'CXx6XSnm76A........'
url = 'https://sandbox.api.visa.com/vdp/helloworld'
headers = { "Accept":"application/json" }
body = {}
r = requests.get(url,
cert = ( 'PATH/cert.pem' , 'PATH//key.pem' ),
headers = headers,
auth = (user_id, password),)

print r.text

# PATH/cert.pem is the one you downloaded in the Credentials page next to my user credential

# PATH//key.pem is the one it ask you to download when I created the project

I have tried the exact same thing and I am getting error: 

Could not find the TLS certificate file, invalid path:
