# 14. Мутация: Създаване на „Field“ или редактиране на границата на съществуващо поле (с опционални етикети)

Създайте "Поле" или редактирайте границата на съществуващото поле.

{% hint style="danger" %}
"Поле" `geojson` атрибутът трябва да е в проекция WGS84 (EPSG:4326), по-малко от 1040 ак / 420 ха, и да следва [спецификация](https://geojson.org/).

Поддържани `geojson` видове са `MultiPolygon` и `Polygon`.
{% endhint %}

Подробности за употребата:

* Атрибут `етикети` е карта с двойки ключ (име на етикет) и стойност (стойност на етикет).
* Възможно е свързване на уникалната идентификация на собствена "Ферма" чрез \
   атрибута. Атрибутът е по избор.
* Атрибути `status` и `statusMessage` маркира резултата от регистрацията. " `"статус"=INVALID` отговор означава, че се изисква разследване на заявката за "Поле". Повече подробности за резултатите са в `statusMessage`.

За да **Редактирате** съществуващото "Поле", добавете `uuid` атрибута към заявката. Разликата е в `uuid` атрибута, който определя "Полето" за промяна на границата.
