We have installed Pega SRS Shared component internally and part of the process we have to provide how other Pega applications (Tenants) interact with Pega SRS component to leverage Pega search functionality.

Is the going to be API call ? if Yes, Provide details around API's like request/ response and TLS/SSL versions and above etc.

This is specifically asked specifically for BOFA enterprise architecture review specifically to understand technology to communicate between Pega Application from/to Pega SRS component.
