I want to expose my PI interface as REST based web service. I also want to use JSON.
i have already searched the internet but did not get any step by step how to doc or example.
My interface is simple. It contains userid as input.
Web service (REST) -> Pi -> Proxy (SAP R/3)
The user passes the userid as the input to the web service. The PI then calls ABAP proxy in a SAP R/3 system.
The R/3 returns user details(First name, last name, Age, Address) back.
How my schema should look like in PI interface? What URL I need to send it to calling application (system that calls the web service)?
What setups I need to do in REST Sender communication channel in order to implement JSON?
