If task_type is set to import_api, the fields include group_id, success (array), failure (array), swagger (structure), and ignore (array). The success array contains four fields: id (ID of a successfully imported API), method (API request method), path (API request path), and action (update or create). The failure array also contains four fields: method (API request method), path (API request path), error_code (import error code), and error_msg (import error message).
