Add a third parameter to a login request using JWT - laravel

Question

I'm working on an api in Laravel and want to edit the login procedure a bit.
Users log in with a username and a password but as a third parameter I want to add an app_id.
This is because usernames can be double in the database when the app_id is different. This is my current login code. It's using JWT as a driver.
$credentials = request(['username', 'password']);
if(!$token = auth()->attempt($credentials)) {
return response()->json([
'error' => ['code' => 1],
'status' => 'error',
], 401);
}
How can I accomplish this?
Kind regards,
Kevin Walter
Edit: My entire AuthController
class AuthController extends Controller
{
public function __construct()
{
$this->middleware('jwt.verify', ['except' => ['login', 'refresh']]);
}
/**
* Login to get JWT credentials
*/
public function login() {
//TODO: LOCKOUT AFTER X AMOUNT OF TRIES
if(!$token = auth()->attempt($this->credentials())) {
return response()->json([
'error' => ['code' => 1],
'status' => 'error',
], 401);
}
return $this->me(true, $token);
}
public function checkPin() {
$username = request('username');
$pincode = request('pincode');
$user = auth()->user();
if($user && $user->username && $user->pincode && $username == $user->username && $pincode == $user->pincode) {
return $this->outputJson(0, 'auth', 'checkPin',[
"firebase_key" => $this->create_custom_token($user->uid, true),
"pin_ok" => 1,
]);
} else {
return $this->outputJson(0, 'auth', 'checkPin', ["pin_ok" => 0]);
}
}
public function me($withToken = false, $token = "") {
$user = auth()->user();
$output = $user;
$output->groups = $user->groups;
$output->categories = $user->categories;
$output->hasPin = $user->hasPin();
$headers = array();
if($withToken) {
$headers["X-TOKEN-RETURN"] = $token;
}
return $this->outputJson('0', 'auth', 'me', $output, $headers);
}
public function logout() {
auth()->logout();
return response()->json(['message' => 'Successfully logged out']);
}
}

It was just as simple as merging the app_id in the credentials. This is the working example!
//Add app ID into the mix of credentials
protected function credentials()
{
return array_merge(request(['username', 'password']), ['app_id' => \request()->header('X-APP-ID')]);
}
/**
* Login to get JWT credentials
*/
public function login() {
//TODO: LOCKOUT AFTER X AMOUNT OF TRIES
if(!$token = auth()->attempt($this->credentials())) {
return response()->json([
'error' => ['code' => 1],
'status' => 'error',
], 401);
}
return $this->me(true, $token);
}
