PO Sender side rest Adapter Feasibility Check.

Hi,

We have a third party scenario where we have a requirement  to use PO Rest Sender Adapter to POST data to SAP PO and then this data will be passed to SAP ECC on Target Side.

Once SAP Receives data Client Want Some Response back for Acknowledgement ( E.g "Received" , "STATUS_OK" ) or something else.

Now My feasibility checks includes following question:-

1. SAP PO REST Sender Adapter supports POST Message method on JSON Data Format?

2. Same PO message will support sharing response back to Sender System (E.g "Received" , "STATUS_OK" ) ?

3. Does it support JSON format?
