I had to update hundreds of domains on a 123-reg account to change the nameservers and forwarding URLs and doing it manually would have taken hours so I wrote this.
Run composer install
Run php artsan migrate
Add your 123 Reg username, password, and optionally a default redirect URL to the env file.
123_REG_USERNAME=
123_REG_PASSWORD=
123_REG_TARGET_URL=
Import your list of domains and target redirect URLs to the domains table in the database.
php artisan dusk
