servicenow side :

you need a client certificate provided by server in java keystore format(contains certs and private key)

you need servers certificate PEM.

Create protocol profile with custom protocol name: myhttps, specify port as 443 or any other 

associated it with client certs(java keystore)

in REST MESSAGES, define your endpoint https://my_remote_api.com, then select mutual authentication and use your protocol profile created

then servicenow will display it as myhttps://my_remote_api.com but when it call, it will call my_remote_api.com:443. 

then it will check server certificate using server certificate u stored as PEM, then validated using CA 

then send over client certs
