It’s important to have the latest PayUmoney payment gateway integration PHP kit. PayUmoney has upgraded the PHP integration kit. Payu has added many security levels. They have included double-verifying security with API and direct payment hash string. You can secure your data.
Yes, I know, you cannot find payumoney latest kit on Payu website but I raised a request for Payumoney integration PHP KIT and they sent me the latest PHP kit.
You can download the Payumoney payment gateway integration PHP kit from Github.
