How to use PRICE_REQUEST REST Web Service call?

@xmlns"

Hello,

We are using Oracle EBS 12.2.7.

We are trying to call the PRICE_REQUEST Web Service (REST), but we are unable to figure out how to provide the parameters properly.

Here is the body of our webservice call:

{

  "LOAD_ROW_Input": {

    "@xmlns": "http://xmlns.oracle.com/apps/fnd/rest/ESKPRICE/price_request",

    "RESTHeader": {

      "@xmlns": "http://xmlns.oracle.com/apps/fnd/rest/header",

      "Responsibility": "ORDER_MGMT_SUPER_USER",

      "RespApplication": "ONT",

      "Org_Id": 204

    },

    "InputParameters": {

      "P_LINE_TBL": [

        {

          "REQUEST_TYPE_CODE": "ONT",

          "LINE_INDEX": "1",

          "LINE_TYPE_CODE": "LINE",

          "PRICING_EFFECTIVE_DATE": "15-MAY-18",

          "ACTIVE_DATE_FIRST": "15-MAY-18",

          "ACTIVE_DATE_FIRST_TYPE": "NO TYPE",

          "ACTIVE_DATE_SECOND": "15-MAY-18",
