### Global Resources Defaults for Symfony

If you need to globally configure all the resources instead of adding configuration in each one, it's possible to do so with the `defaults` key:

      shared_max_age: 3600

      # Default values of the "Vary" HTTP header.
      vary: ['Accept']

      invalidation:

### Global Resources Defaults for Laravel

If you need to globally configure all the resources instead of adding configuration in each one, it's possible to do so with the `defaults` key:

```php
<?php
// config/api-platform.php

use ApiPlatform\Metadata\UrlGeneratorInterface;

return [
    'defaults' => [
        'description' => null,
        'iri' => null,
        'short_name' => null,
        'item_operations' => null,
        'collection_operations' => null,

        'graphql' => null,

        'elasticsearch' => null,

        'security' => null,
        'security_message' => null,

        'cache_headers' => [
            // Automatically generate etags for API responses.
            'etag' => true,

            // Default value for the response max age.
            'max_age' => 3600,

            // Default value for the response shared (proxy) max age.
            'shared_max_age' => 3600,

            // Default values of the "Vary" HTTP header.
            'vary' => ['Accept'],

            'invalidation' => [
                'xkey' => [
                    'glue' => ' ',
                ],
            ],
        ],

        'normalization_context' => [

        'pagination_client_enabled' => false,

        // To allow the client to set the number of items per page.
        'pagination_client_items_per_page' => false,

        // To allow the client to enable or disable the partial pagination.
        'pagination_client_partial' => false,

        'url_generation_strategy' => UrlGeneratorInterface::ABS_PATH,

        'collectDenormalizationErrors' => false,
    ],
];
