Hi I'm tryinng to get access token using the below post URL https://accounts.adp.com/auth/oauth/v2/token?grant_type=client_credentials&scope=api and I'm setting basic authorization in header. While requesting I get 401 error.
"error_description": "proper client ssl certificate was not presented"
Can anyone help?
It looks like you will need to resolve the issue of ADP issued client certificate first. https://developers.adp.com/articles/general/introduction-mutual-ssl (Mutual TLS/SSL Help from ADP Dev Site). You will need to contact your ADP support team if they have not issued you a client API (SSL) cert yet.
