First of all you can call your server api for generate checksum. If you are using Almofire then call

var parameters:[String:String]?
        parameters = ["MID":strMid,"ORDER_ID":strOrderId ,"INDUSTRY_TYPE_ID":strIndustryType,"CHANNEL_ID":strChanalID,"TXN_AMOUNT":strAmt,"WEBSITE":strWebsite, "CUST_ID":strCustomerId,"CALLBACK_URL":"http://xxxxxxx.co.in/verifyChecksum.php"]
                    showHud(self.view)
        print(parameters)

        Alamofire.request("http://xxxxxx.co.in/generateChecksum.php", method: .post, parameters: parameters,encoding: URLEncoding.default, headers: nil).responseJSON {}

Please pass all parameter in this api . It gives below response

{
  "CHECKSUMHASH": "xxxxxxxxxxxxx",
  "ORDER_ID": "xxxxxxxx",
  "payt_STATUS": "1"
}

In this Dictionary you get CHECKSUMHASH It Pass into paytm order.
