Question

I have published one Process model as a webservice.
This process model processes the inputs and creates some result, which is stored in a process variable.
How can I configure this service to return the process variable value?

Hi dipaki , 
 
If you are using Web api then on success you just need to use that PV. 
 onSuccess: a!httpResponse( 
 statusCode: 200, 
 headers: { 
 a!httpHeader(name: "Content-Type", value: "application/json") 
 }, 
 body: a!toJson( 
 fv!processInfo.pv 
 ) 
 ) 
 
this will return you process variable value. 
Hope this will help you. 
 
Thanks, 
Sandeep

Hello Dipaki, 
 
The best way is to do this by WebAPI but if you can also get the process variable values in your case 
by using a shared component named as "Synchronous Process Model Web Service" this will return your pv instead of returning only process ID. 
 
I hope this can help. 
 
Thanks

This is not a feature available with that configuration OOTB. If you want to return more than the process ID, the recommended approach is to create a WebAPI instead. In that WebAPI, start your process, and retrieve variables from the output. See the following references: 
 
 docs.appian.com/.../Designing_Web_APIs.html 
 docs.appian.com/.../Start_Process_Smart_Service.html 
 
Alternatively, there are some plugins like Sync. PM Web Service that can do what you are asking for though I recommend staying with OOTB features if possible - forum.appian.com/.../summary
