Require the vatusa/php-uls package in your composer.json and update your dependencies:
```
$ composer require vatusa/laravel-uls
```
Generate the configuration file

Configuration

For php-uls to work you need to configure your jwk, uls version, and facility id. These are set through an options array in the constructor:

$options = [
 "version" => 2,
 "jwk" => $jwk,
 "facility" => "ZZZ"
];
$uls = new \Vatusa\Uls\Uls($options);

Using laravel-uls is fairly easy.

Get your JSON Web Key from your facility's Technical Configuration page. https://www.vatusa.net/mgt/facility (NOTE: You must hold a ATM, DATM or WM role for that facility to generate/see the generated JSON Web Key)
Store the JWK, unedited, in the config above (or, recommended quoted with single quotes in the .env file as ULS_JWK='... JWK from VATUSA...')
To generate the redirect url, use:
```
$uls->redirectUrl()
```
To handle the developmental returns, specify a boolean argument of true
```
$uls->redirectUrl(true)
```
To verify a token, assume $token is the full token received from VATUSA's ULS endpoint
```
$uls = new Uls($options);
if ($uls->verifyToken($token)) {
 // Token was true
}
```
The laravel-uls library conducts header verifications to ensure that the accepted algorithms are received. Additionally, it conducts the following claims checks, including:
- Ensures the audience is you (IE, the token isn't meant for another facility)
- The token is not expired
- The Issued at time is logical (ie, not in the future)
Because of this, a number of exceptions may be thrown:
- InvalidArgumentException
- Jose\Component\Checker\InvalidClaimException
- Jose\Component\Checker\InvalidHeaderException
To get the information of the user associated with the token, use:
```
$uls->getInfo();
```
This will return an array of the decoded JSON from ULS. Details of the array can be found in the VATUSA Technical Manual M1022 at https://www.vatusa.net.
