Requests.json- Pick api key

Hi Team,
I need to pick token from iparams json to request json but it shows that the token cannot be picked.

requests.json

{

    "getFsuAccount":{
        "schema": {
            "protocol": "https",
            "method": "GET",
            "host": "<%= iparam.freshsuccess_url %>",
            "path": "/api/v2/accounts/<%= context.account_id %>",
            "headers": {
                "Content-Type": "application/json"
              },
            "query": {
                "api_key": "<%= iparam.freshsuccess_token %>" 
            }
            }
        }
    }
    

iparams.json

      "freshsuccess_token": {
          "display_name": "Freshsuccess API Key",
          "description": "Please enter your Freshsuccess API Key",
          "type": "api_key",
          "secure": true,
          "required": true,
          "type_attributes": {
            "product": "Freshsuccess"
          }
          },

CURL from postman:

curl --location ‘https://api-eu.freshsuccess.com/api/v2/accounts/freshservice - 202546?api_key=us-****’

Can someone help?
