Stripe API get customer information

Getting a Stripe customers information is a common task to that then making a reusable method.

I’m using Nova Framework not setup with Nova? please read Getting Stripe API setup with Nova Framework

First, check the user is logged in if not return. Next get the customer id from the database, if it's empty then return.

Attempt to get the customer from Customer::retrieve()

Lastly, check if the user has been deleted from Strip if so save its state in the database and return the customer array

protected function getCustomer()
{
    //if not logged in return
    if (!Auth::check()) {
        return null;
    }

    //assign stripe customer from db
    $stripe_customer_id = Auth::user()->stripe_customer_id;

    //no customer id
    if ($stripe_customer_id == null) {
        return null;
    }

    //get customer record from stripe
    try {
        $customer = Customer::retrieve(
            array("id" => $stripe_customer_id, "expand" => array("default_source"))
        );
    } catch (Exception $e) {
        dd('Stripe Customer not found! Error: '.$e->getMessage());
    }

    //if stripe customer has been deleted
    if ($customer->deleted == true) {

        //remove stripe link
        $user = User::find(Auth::id());
        $user->stripe_customer_id = null;
        $user->save();

        return null;
    }

    return $customer;
}
