How to encrypt request payload for HCM Extract API FlowActionsService.submitFlow?

hi All,

We have developed a HCM Extract for our clients to fetch employee details with SSN being a parameter. We will invoke the extract using FlowActionsService.submitFlow SOAP call. As SSN being sensitive information, how can we encrypt the request body?

Thanks,

Veena
