## Global Resources Defaults

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:

```yaml
# api/config/packages/api_platform.yaml
api_platform:

    defaults:
        description: ~
        iri: ~
        short_name: ~
        item_operations: ~
        collection_operations: ~

        graphql: ~

        elasticsearch: ~

        security: ~
        security_message: ~
        security_post_denormalize: ~
        security_post_denormalize_message: ~

        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']
