HTTPCaller to specify client certificates

Very much needed! Please implement this feature.

This would also be useful for an ongoing project with our organization.

DTAG also requires this...

Edit: For anyone who also needs to use the DTAG Telekom MB2B REST API, here's my Python Code to get the contract list:

Startup-Python-Script

global cert
global key
 
cert = FME_MacroValues['FME_SHAREDRESOURCE_DATA'] + "certs/Telekom/cert.crt"
key = FME_MacroValues['FME_SHAREDRESOURCE_DATA'] + "certs/Telekom/private.key"

PythonCaller:

import fme
import fmeobjects
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry
 
class FeatureProcessor(object):
    def __init__(self):
        pass
        
    def input(self, feature):
        headers = {
            "Authorization": "Bearer " + feature.getAttribute('token'),
            "Customer-Number": feature.getAttribute('RELATEDPARTY')
        }
        
        url = \
        FME_MacroValues['URL'] + \
        "productInventoryManagement/" + \
        FME_MacroValues['VERSION'] + \
        "/product?agreement.id=" + \
        FME_MacroValues['FRAMECONTRACT'] + \
        "&relatedParty.id=" + \
        feature.getAttribute('RELATEDPARTY') + \
        "&productOrder.externalId=00000&filter.product.type=tariffList&limit=0"
        
        
        retry_strategy = Retry(
            total=3,
            status_forcelist=[400, 429, 500, 502, 503, 504],
            allowed_methods=["HEAD", "GET", "OPTIONS"]
        )
        adapter = HTTPAdapter(max_retries=retry_strategy)
        http = requests.Session()
        http.mount("https://", adapter)
        http.mount("http://", adapter)
 
        response = http.get(url, headers=headers, cert=(cert, key))      
                
        feature.setAttribute("contracts_list",response.text)
        self.pyoutput(feature)
        
    def close(self):
        pass

This is recurring request for us as well.

Hope the issue is realized soon!

I suggested the same thing back in 2020, but sofar nothing :-(

This is increasingly important, as more and more APIs are getting stricter access control. We are seeing a marked uptick in the number of private API endpoints that now require using a client certificate, which unfortunately can only be done using non-trivial Python code. 

Suggestion: implementing an option in the HTTPCaller to specify a PKCS#12 (.p12) certificate archive and associated password would help a very long way. This would be the equivalent in cURL:

$ curl --cert-type P12 --cert <cert-file.p12>:<password> https://api.example/endpoint

@richardatsafe​ @steveatsafe​ Any chance of getting this into 2024?

pushing for it... (but I won't pretend I have any weight on the decision to move on this).

It's getting harder to not support this.
