"rohit/line-pay": "^3.0"

Run composer install to get the latest version of package

Or you can directly run the composer require command

After the package install is completed you need to configure config/app.php and add Providers and Aliases

    'providers` => [
        .......
        .......
        Rohit\LinePay\LinePayServiceProvider::class
    ]

    'aliases' => [

After the above steps, you need to publish vendor for this packge. It will create line-pay.php file under config folder. This folder contains the configuration for your locales.

php artisan vendor:publish --provider="Rohit\LinePay\LinePayServiceProvider"

The file line-pay.php will contain the following structure
