Larship Hooks a beautiful way to add you extra actions to events fired, also filtering data passed or returned, for example :

On subscription creation call an external API,

On Save User Data Sync it with other CRM

on Deleting Object send email to ...

and many more cases required for your business.

Hook Actions:

let's assume you want to send email on subscriptions cancellation then on your plugin service provider add this to your register() function :

\Actions::add_action('pre_cancel_subscription', , 10);

10 shows the priority of executing hook, you need to make sure that priority is unique for hook actions

and then add in your hook Class the function

public send_email( $user, $plan){

....

}
