Please show me how to login to Postman using the API. I have uploaded the.pfx file successfully now, but I am getting an error.

I am a beginner trying to log in to McMaster-Carr API. I have a.pfx authentication file, an API password, and my main login/password (email/account password). I have imported the.json file into postman and have inputted my main login credentials in the fields below, but I am not getting a success output message. I am confused as to where the API key/password goes and where I upload the.pfx file as well.
