      define(‘PAYTM_ENVIRONMENT’, ‘PROD’); // Use PAYTM_ENVIRONMENT as ‘PROD’ if you wanted to do transaction in production environment else
      //Or

      define(‘PAYTM_ENVIRONMENT’, ‘TEST’); // ‘TEST’ for doing transaction in testing environment.
      define(‘PAYTM_MERCHANT_KEY’, ‘bKMfNxPPf_QdZppa’); //Change this constant’s value with Merchant key downloaded from portal
      define(‘PAYTM_MERCHANT_MID’, ‘DIY12386817555501617’); //Change this constant’s value with MID (Merchant ID) received from Paytm
      define(‘PAYTM_MERCHANT_WEBSITE’, ‘DIYtestingweb’); //Change this constant’s value with Website name received from Paytm

      Please use original keys from Paytm Website and then check for Production Environment.
      As above written keys are for Testing Environment only.
