Does Laravel Session has a unique key?

what key?

So I need to store a booking in the session and then send a session ID over to the payment provider, a​nd after the customer pays, then they will redirect to my site, match up the ID's and continue with the booking.

An example of finding a session of the created_id. This looks for the key created_id

        $project = Project::where('user_id', auth()->id())->find(session('created_id'));

        return view 

    }```

raw php 
```<?php
function session(
    $key = null,
    $default = null
) { }```

Just for testing, I'm doing it like this:

$form = collect($request->all());

Session::put('form', $form);

return $request->session()->getId();

return session('form');

And this is just for testing, I was thinking to generate a 30 letter word and hash it and store it in the session, and then check if they are the same.

You asking a pretty basic question about session which at the state you are at doing eCommerce you should know already

If you recall in another discussion another user sort of asked you to slow down and learn some stuff without advancing too fast.

It would just be a good idea to learn some of these basic concepts first.

Of course each user session is unique to that logged in user.

In my case,​ I don't have any logged-in user.

A created session is unique to that session and that browser.

And how can I get a data from that session when a customer comes back to the site after a redirect from another site.

Most gateways will return to your site with a URL you specify, in that URL have the correct information to continue whatever you need to continue with.

You would probably benefit from looking over several different Gateway apis and how they work.

I created my own session key to send over to the payment provider
