Use the NEW rest-API endpoint instead:

POST runtime/process-instances, passing in:


{
   "processDefinitionKey":"loanrequest",
   "variables": [
      {
        "name":"income",
        "value":150000,
        "type": "long"
      },
      
      … 
   ]
}

See userguide on more details on variable-format and typing

Thanks for quick reply. I might be missing something. The API /process-instances is for retrieving the details about the active process instances. This is as per the user guide available here: http://activiti.org/userguide/index.html#N16747

The problem that I am encountering is related to the API that starts the process instance:
<blockcode> Request: POST /process-instance </blockcode>
