Enabling paytm payment gateway on kitsune websites

I am trying to enable Paytm as my payment gateway in the ecommerce website i am creating using kitsune.

When i enable the Paytm component in the IDE, i can see the following in my kitsune-settings.json file (the preview section)

"preview": [
  {
    "domain": "example.com",
    "gateway": "paytm",
    "api_secret": "API_SECRET",
    "api_key": "API_KEY",
    "redirect_path": "/transaction_status",
    "api_url": "https://pguat.paytm.com",
    "payment_request_endpoint": "/oltp-web/processTransaction",
    "transaction_status_endpoint": "/oltp/HANDLER_INTERNAL/getTxnStatus?JsonData="
  }

Where do i find the right values for API_SECRET and API_KEY ?
