How to integrate PayU Money Bolt in Laravel?

I want to integrate the Payu Money bolt payment gateway for my Laravel project. I tried directly using the bolt php kit that they provided on their site but after submission I kept getting an error called method not allowed exception.

Also, do I have to use @csrf and @method('get')? I'm already using it, I just need clarification.

I also tried implementing the code from this tutorial but it didn't work. https://www.bladephp.co/integrate-payumoney-payment-gateway-in-laravel5
