Proc http request using client side certificate

Andreas_M5 — Thu, 31 Jan 2019 04:59:15 GMT

Hi.
I am looking for help with a seemingly simple task. I am looking to call a Rest API that requires me to have a client side certificate with a correct role to get access to some sensitive information.

I am hoping to be able to use base SAS and prof http requests - but I am having trouble how to provide the certificate.

The cert file is in both p12 and pem format if that makes a difference.

Please, could any of you provide me with some tips or help to get started on this?

Cheers.

PROC HTTP respects the SSL* options that you can specify in your SAS session, which includes options related to certificates. See the Encryption in SAS documentation. As of SAS 9.4m6, you can also include these values in a new SSLPARMS statement.

Hi Chris

sorry for pinging and old post but I ma having the same difficulty and yes I have tried both setting ssl options for environment var by putting in front of my script or using sslparms yet cannot get positive response from our internal API. in order to test if the SAS code works I have created session from programming runtime machine and execute same code , it works flawlessly. Does any service overrides these sslparms value while executing it from sas studio ? we are using viya 3.5

Hi @bugraduman1,

Are you saying the SAS code works from another environment (like Local SAS) but not from within SAS Studio in Viya? It does sound like a cert/trust issue, or maybe firewall/network. I recommend first gathering more information by using the DEBUG LEVEL=3 statement in PROC HTTP, and making sure that other PROC HTTP calls can work from your SAS Viya environment. If these diagnostics don't yield anything, then I recommend working with SAS Technical Support -- they can direct some more tests/steps.
