What is the technical literature on e-commerce?

Question

Laravel

I am interested in literature on the technical part of e-commerce, electronic transfers and electronic money in general.
I would like to read about the general approaches used to implement and design systems for receiving, sending electronic money and payments , about the features and problems that programmers face when developing such systems.

Answer 1

public function __construct()
{
    $this->middleware('check.auth:my_parameter');
}

PS The base controller does not have a constructor, so this is parent::__construct();not needed.

Answer 2

Such literature becomes obsolete even before publication.
Read the documentation for the desired services.
Why do you need a retelling of this documentation?
