Via the JSON file, it is possible to determine the default value of a field via an HTTP request. There are the following possibilities:

1) Programmed Controller Endpoint

2) Dynamic API (SQL)

Instead of a value, an entire object is specified. The attributes are described below.

Controller endpoint

Property	Description
url	The URL of the endpoint
params	This attribute is a list of KeyValue pairs. Here you can give the URL individual parameters. "key" contains the name of the parameter and "value" the value.
requestType	Here you can specify whether the query is a "get" or a "post" query.

"defaultValue": {
	"requestType": "get",
    "url": "ResourceController/GetName",
    "params": [
    	{
        	"key": "Id",
            "value":  "42"
        }
    ]
}
