Prerequisites to Use Rest Adapter in

hi All,

Could you please tell me how we can use Rest adapter in PI ,does SAP has its own adapter or we need to download from any

third party source,if SAP has its own do we need to install as third party.

I need to do a POC  on  source as  (XML format) to Target REST (JSON format) within SAP and sent it out to external applications

using Rest protocol.

Your Help is highly appreciated.
