 This package allows you to setup Paddle webhooks locally in just one command, thanks to [tunnelmole](https://tunnelmole.com/). When the command is killed, it removes the webhook from Paddle. The library only works in *sandbox* mode.

 This is **heavily** inspired from this [awesome command](https://github.com/lmsqueezy/laravel/blob/main/src/Console/ListenCommand.php) made by the LemonSqueezy team for their [Laravel package](https://github.com/lmsqueezy/laravel). Kudo to them! :heart:
 
 The difference with the original package is that Paddle doesn't allow to create a webhook with a specific webhook secret. It's automatically generated by Paddle (on the contrary to LemonSqueezy). This means I had to add a few steps to make it work.
