You can exclude response codes indicating shadow endpoints using the environment variable APIFW_SHADOW_API_EXCLUDE_LIST.
• Configuration of the HTTP response status code returned by API Firewall to blocked requests (via the environment variable APIFW_CUSTOM_BLOCK_STATUS_CODE).
• Ability to return the header containing the reason for the request blocking (via the environment variable APIFW_ADD_VALIDATION_STATUS_HEADER). This feature is experimental.
• Configuration of the API Firewall log format (via the environment variable APIFW_LOG_FORMAT).
