Usually this is a cropping scheme.
So when the code of the crop field is known, use this code as parent code to create the crop field and go to the next chapter.
## Get cropping scheme
When the cropping scheme code is not known, we need to start from the top of the hierarchy, which is my_roots.

So the `parentcode` we need is **"f25d8765a1cd407cb235961c73c268cf:USER_FILES"**
You can also find the code of a folder by browsing the folders in your FarmMaps account through the web interface.
The item code is the last part of the URL.
### Create folder In the list returned, search for item which ends with USER_IN, which is shown above.
Depending on how you want to organise things, you might choose to make a separate folder for the cropfield. This item will be the parent of the cropping scheme.
A folder can be created by creating an item with itemType `FOLDER`.
> **Note:** At the moment, subfolders can not be created directly under the root folder, create a folder through the web interface first. So make another call to check if a cropping scheme exist.

When the list is empty, you need to create a new cropping scheme, which is described in another thread.
The `parentcode` we need for creating a crop field is **"f3ee8e3ac55b43bc89757bcaedc89992"**

Generally, a cropfield contour would be defined as a polygon, so we add `"type":"Polygon" and all the coordinates. Generally, a cropfield contour would be defined as a polygon, so we add `"type":"Polygon" and all the coordinates.
