How to implement GTPay in laravel 5.1 ?

It is mandatory to include the hash tag on all mandatory parameters sent to GTPay gateway so as to guard against middle man attack. These parameters include;

–       GTPAY Transaction ID
–       Transaction Amount
–       Transaction Notification URL
–       Transaction Currency

Kindly carry out transaction re-query and verify that the transaction details (including currency) are accurate for every transaction.

You are required to perform a sha512 hash of [gtpay_mert_id,gtpay_tranx_id,gtpay_tranx_amt,gtpay_tranx_curr,gtpay_cust_id,gtpay_tranx_noti_url,gtpay hash]

There is a site that you can use to generate a hash parameter and compare with what your site is generating.

The url is http://www.fileformat.info/tool/hash.htm


<?php

$the_key = trim('4329'.'65124534569'.'9900'.'566'.'4244327'.'avianceschool.com'.'xxxxxxxxxxxxxxx');

$HASH = hash('sha512',$the_key,false);

?>
