How do I allow other sites to receive data from your site?

More details

I am new to RESTful API and Laravel world.

But "Every artist was an amateur at first. Let him get to the point.

I have 2 sites. Let's call it:

• A
  
  
• B
  
  

The website B

has a good list if the table of users + all of its relation.

I want to allow the website A

to access the website B

and download this nice data.

I've never done this. I guess the logic is:

• On the website, A
  
  you need api_keys to access the website B
  
  .
• Then, after the api_key matches, the website B
  
  will return the data to the website A
  
  as a json file.
• The website A
  
  will then receive this json file and load it into HTML and render it.

Is my logic even close? Please correct me if I am wrong. :)

Here is what I have tried

After some research, I came across this site . I really liked it. I've finished everything. Now I will get a little sense of the RESTful API.

Then I came across this site . I found this

filters.php

Route::filter('api', function() {

    // Fetch a user record based on api key
    $user = User::where('api_key', '=', Input::get('api_key'))
                ->take(1)
                ->get();

    if ($user->count() > 0) {
        Auth::onceUsingId($user[0]->id); // Authorize the user for this one request
    } else {
        return Response::view('errors.404', array(), 404)->header('Content-Type', 'application/json');
    }
});

      

        
        
        
      

    

I notice the OP of this saved api_key

in the users table.

My questions

• Do I need to do it like him?
• Is this the only way to do it?

• Is there a better / easier way to do this?

• Instead of grabbing the api_key from the database, can I just manually set it to a random
  
  number + text like this? 21sdf364rt7y6r5ty1u28x1h8gt7yt2ert3654871 ??

• How long will it expire api_key
  
  ? Is it even expire
  
  ? How do we know this?

Again, my main one goal

is to let the website A

access content from the website B

.
