I am calling the Post API

engine-rest/process-definition/key/EMP_SEARCH_WORKFLOW/start

I am calling the above API through the angular but I am getting a success message. I am sending the parameter below

commodity: “Milk”
customerCode: “2343”
customerName: “sam”
emailId: “kithiyonmca@gmail.com
[[Prototype]]: Object

after that, in the cockpit, I am not receiving the parameter why?

http://localhost:8080/engine-rest/process-definition/key/mydefinitionkey/start

I am using my localhost but Request got success but parameter is not available in cockpit
