# Task fields

Manage the task field schema. All operations require the `task` scope. The system fields `UF_CRM_TASK`, `UF_TASK_WEBDAV_FILES`, `UF_MAIL_MESSAGE` are returned with `system: true` and are protected from modification and deletion. Field values are read and written through [/v1/tasks](/docs/entities/tasks). This section covers schema details and list options. Reads are available to a key in read-only mode; writes require read-write mode and Bitrix24 account administrator rights.
