Hi,

I have a similar requirement where a process model is exposed as a webAPI. On completion of process, value of pv!statusCode (based on some logic) is generated. I want this statusCode to be sent in response of webAPI whenever called by an external system. Can you please how to implement this?

You can use Synchronous Process Model Web Service plug-in (a Shared Component)

Expose your process model as web service using this plug-in, so that the web service will be synchronous (the WS call will wait until the chain of activity is broken, before returning the PV values to the client).

Although, the service will be available as SOAP WS, not REST-ful API.

You can try to call the above SOAP WS with webservicewrite() function from within your Web API implementation. If Basic Authentication (which is required by the SOAP WS) is supported by webservicewrite() function, then you got a solution.

Have activity chaining between the all the nodes in the PM including the Start and End.

From the documentation: "The new process is started asynchronously and the process flow of the current process continues immediately after the new process starts.
"
In the current implementation you cannot get PVs from the process.
