Some objects contain custom fields. Those fields are treated as one JSON field.
The field has the following properties :
1. It is possible to add has many fields deemed interesting.
2. custom_fields added through the Manatal application will be reflected in this JSON field
3. Adding custom_fields through the API will not add them to the Manatal application
4. Modifications of existing fields will be reflected in the Manatal application
5. When editing the field, a full overwrite is performed
When editing custom_fields, it is mandatory to pass the full custom_field object.
Because an overwrite is performed not passing the full JSON object will cause loss of all the data that was previously present.
Manatal will not be held responsible for loss of data on the custom_fields.
