Sending values from external system to Appian database using web api start process but do not know the settings on process model

Question

Hi Team, 
 
 I want to know the configuration to be done on the process model in my case. 
 I have created a WebAPI object to start the process model (my process model is empty for now), this external application is doing POST. 
 But where can I see the JOSN body of the data the external system is sending to the Process model? 
 
 many thanks

I got the answer, I used the process variables with the exact name of the JSON value being sent and I was able to see the value while checking process instances
