General Configuration 

You can change the following general configuration options via Resources/config/oro/app.yml in any bundle or config/config.yml of your application.

oro_api:

    # The prefix of REST API URLs.
    # The default value is "/api/".
    rest_api_prefix: '/api/'

    # The regular expression pattern to which REST API URLs are matched.
    # The default value is "^/api/(?!(rest|doc)($|/.*))".
    rest_api_pattern: '^/api/(?!(rest|doc)($|/.*))'

    # The default page size. It is used when the page size is not specified in a request explicitly.
    # The default value is 10.
    default_page_size: 10

    # The maximum number of primary entities that can be retrieved by a request.
    # The default value is -1, which means unlimited.
    max_entities: -1

    # The maximum number of related entities that can be retrieved by a request.
    # The default value is 100.
    max_related_entities: 100

    # The maximum number of entities that can be deleted by one request.
    # The default value is 100.
    max_delete_entities: 100

To change the maximum number of entities retrieved by a request for a specific API resource, use the max_result option in Resources/config/oro/api.yml. For details, see entities and actions configuration sections.
