How to integrate paytm in laravel website

I have done paytm integration with my website using paytmwebkit

I have downloaded the paytm kit and read the following details:

Copy PaytmKit folder in document root of your server (like /var/www/html) Open config_paytm.php file from the PaytmKit/lib folder and update the below constant values PAYTM_MERCHANT_KEY – Can be downloaded from the Paytm portal. One time downloadable PAYTM_MERCHANT_MID - MID (Merchant ID) can be collected from Paytm team PAYTM_MERCHANT_WEBSITE - Website name can be collected from Paytm team PaytmKit folder is having following files: TxnTest.php – Testing transaction through Paytm gateway. pgRedirect.php – This file has the logic of checksum generation and passing all required parameters to Paytm PG. pgResponse.php – This file has the logic for processing PG response after the transaction processing. TxnStatus.php – Testing Status Query API

I am new to laravel. I have done all these.how can I redirect to paytm gateway using my submit button?
