Spotify API php - unable to request data and get access token - php

Question

I am currently new to using php and Laravel and working with an API however I have been following the Spotify PHP tutorial https://github.com/jwilsson/spotify-web-api-php.
I've also put in bold some of my questions that I wanted to ask , hopefully someone can help.
I have followed all steps but need help just to get it working.
Put the following code in its own file, lets call it auth.php. Replace CLIENT_ID and CLIENT_SECRET with the values given to you by Spotify.
(Where abouts should I save this file?)
The REDIRECT_URI is the one you entered when creating the Spotify app, make sure it's an exact match.
(I used my localhost:8888/callback/ not sure if that is correct?) Obviously I haven't put me details in here on this website as for security reasons.
<?php
require 'vendor/autoload.php';
$session = new SpotifyWebAPI\Session(
'CLIENT_ ID',
'CLIENT_SECRET',
'REDIRECT_URL'
);
$options = [
'scope' => [
'playlist-read-private',
'user-read-private',
],
];
header('Location: ' . $session->getAuthorizeUrl($options));
die();
?>
When the user has approved your app, Spotify will redirect the user together with a code to the specifed redirect URI. You'll need to use this code to request a access token from Spotify.
put this code in a new file called callback.php:
Do replace client id and secret with my detail? also how do I save the access token?
require 'vendor/autoload.php';
$session = new SpotifyWebAPI\Session(
'CLIENT_ID',
'CLIENT_SECRET',
'REDIRECT_URI'
);
// Request a access token using the code from Spotify
$session->requestAccessToken($_GET['code']);
$accessToken = $session->getAccessToken();
$refreshToken = $session->getRefreshToken();
// Store the access and refresh tokens somewhere. In a database for example.
// Send the user along and fetch some data!
header('Location: app.php');
die();
In a third file, app.php, tell the API wrapper which access token to use, and then make some API calls!
(Where do i also save this file and how do I make these calls in my Laravel Controllers?)
require 'vendor/autoload.php';
$api = new SpotifyWebAPI\SpotifyWebAPI();
// Fetch the saved access token from somewhere. A database for example.
$api->setAccessToken($accessToken);
// It's now possible to request data about the currently authenticated user
print_r(
$api->me()
);
// Getting Spotify catalog data is of course also possible
print_r(
$api->getTrack('7EjyzZcbLxW7PaaLua9Ksb')
);

(Where abouts should I save this file?)
You can save this file in differents places in laravel, for testing you could write it in a controller (not the best but you can).
Do replace client id and secret with my detail?
Yes of course !
also how do I save the access token?
You can save in a database or in a session or where you want. If you store it in a session you will have to make a new request to get a new Access token if the user logged out of your application. In a database you can reuse it.
Many access token are only available for a specific duration. The spotify doc should speak of it.
(Where do i also save this file and how do I make these calls in my Laravel Controllers?)
For testing you can do this in your controller, but it's a good idea to have a service layer where you put the business logic of your application.
Do not copy require 'vendor/autoload.php'; in your file laravel handle the composer autoload already.
