HTTP to RFC scenario with URL parameters

Hi All,

I am working on HTTP to RFC scenario using an interface in SAP PI.

The data will be pushed from API link via 4 URL parameters viz. UID, mobno, phone1, phone2.

My query is what will be the UDF code for the same.

Also how to design & configure the same scenario in SAP PI, since I'm working on this scenario for the first time.

on SAP end, what will be more comfortable to have RFC or Proxy?

Thanks & Regards,
