Setting up HTTPS on Reverse Invoke

We are implementing inbound to Reverse Invoke for the first time, SSL / HTTPS communication. For setup, the steps that I followed are: import client certificates into “Security - Certificate” link. The partner certificate shows up in the “Current Certificate” location. I can view their certificate installed under the “Configure Client Certificates”. That is all that we have done. Question is, once the partners certificate is installed, anything else that needs to be done for connectivity to work?
