Hi Ramu,

In the request received by PI server the request comes in form of HTTP request. Such request has a header part and body part.

In case you are trying to access a value coming in header you need to access the same using header variable.

In a REST (GET) request there will be parameters in query string as shown below


here start1,start2 are values you can obtain by specifying value source as "GET variable" in sender channel .
