Typically, you don't need to store mobile passes as they will be generated on the fly when a user tries to download it.

However, if you want to store the pass for later use, you can do so by using the generate method on a MobilePass model.

use Spatie\LaravelMobilePass\Models\MobilePass;

$mobilePassContent = $mobilePass->generate();

file_put_contents('path/to/store/pass.pkpass', $mobilePassContent);

##Generating a mobile pass without a model

If you don't want to create MobilePass model, you could also call generate on one of the mobile pass builders.

$mobilePassContent = AirlinePassBuilder::make()
    ->setOrganisationName('My organisation')
//  other calls
    ->generate();

file_put_contents('path/to/store/pass.pkpass', $mobilePassContent);

The code above will not create a MobilePass model. Be aware, that if you create a pass this way that users will not be notified when the pass is updated.
