Custom Fields

The Custom Fields object allows you to view, create, update, and delete extra fields for additional Estimate, Project, Group, Resource, Task, and User information. If Custom Fields represent the fields themselves, Custom Field Values represent the values in/of those fields.

Fetching a list of Custom Fields

Returns all Custom Fields, unless filter parameters have been applied.

This endpoint returns structured Custom Field objects. As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the results array and will be indexed by ID in the custom_fields top-level JSON key. Please see our Response Format section for more information.

Creating a new Custom Field
This endpoint returns structured Custom Field objects.
As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the results array
and will be indexed by ID in the custom_fields top-level JSON key.
Please see our Response Format section for more information.


Request 
query Parameters
include
string
Any of the below associations can be included in your request by providing the include param, e.g. include=association1,association2.


    

  • choices (CustomFieldChoice) - Includes the ID of a Custom Field's choices.
    • 

  • creator (User) - Includes the ID of a Custom Field's creator.
    • 

  • custom_field_set (CustomFieldSet) - Includes the ID of the Custom Field Set that a field belongs to.
    • 

  • external_references (ExternalReference) - Includes references to external integrations for this object.
    • 



 
Request Body schema: application/json
required
object
 
name
required
string
The name of the new field.


 
value_type
required
string
The format of the custom field's value:






Value Type
Format
Sample





string
<text_string>
"foo"




date
<ISO_8601 Date Format>
"2014-02-25"




number
<integer_value>
13




currency
[<int_value_in_cents>, <currency_code>]
[998, "USD"]




single and multi
[<choice_ids>]
[1, 2, 4]





This is set to string by default.


 
default_text
string
The message in an empty custom field, before a string, date, number, or currency  value is entered in.
This only appears in the UI.


 
unique_constraint
boolean
A boolean setting that requires a custom field value to be unique across Estimates, Projects, Groups,
Resources, Tasks, or Users.


This is set to false by default.


 
Array of objects
The list of choices a user can select from
for a custom field's value(s). A choice has two attributes, a label and an ID. Different choices can have the
same label, but every choice will have a unique ID.


For example, a request:


custom_field_choices: {
  ....
  choices: [
    { "label": "Choice A" },
    { "label": "Choice B" },
    { "label": "Choice B" },
    { "label": "Choice B" }
  ]
  ....
}

Will have a response like:



custom_field_choices: {
  ....
  choices: [
    { "label": "Choice A", "id": "180291" },
    { "label": "Choice B", "id": "180301" },
    { "label": "Choice B", "id": "180311" },
    { "label": "Choice B", "id": "180321" }
  ]
  ....
}


```


Choices in the UI appear in the same order as listed in the array.


Note that the 2nd, 3rd, and 4th choices all have the same label, but different IDs.


 
custom_field_set_id
required
integer <int32> 
The ID of the Custom Field Set that the field belongs to.
When a set ID is not specified, the field is added to a Project set titled 'Default Project Set'.
This means it becomes a Project field.


 
write_access
string
The permission level required for a user to create, update, or delete a custom field's value.


 
read_access
string
The read_access permission setting on each custom field
determines the minimum permission needed to view a custom field and its value.


    

  • Workspace (Project), Resource, and Story (Task) custom fields are project-specific objects,
so their minimum permissions are set at the project level:
      

    • project_collaboration (default)
      • 

    • time_logging
      • 

    • financial
      • 

    • project_admin
      • 

    

    • 



Most account-level permissions supercede project-level permissions. Therefore, Account Administrators are able to view
all Project, Resource, and Task custom fields and values across the account, regardless of project participation or
read_access settings.


    

  • Estimate, WorkspaceGroup (Group), and User custom fields are account-wide objects, so their minimum permissions
are set at the account level:
      

    • account_collaboration
      • 

    • project_creator
      • 

    • project_lead
      • 

    • reports_viewer
      • 

    • reports_viewer_with_cost
      • 

    • account_admin (default).
      • 

    

    •

Updating an existing Custom Field
Updates an existing custom field. 


Parameters that cannot be updated


Note that the unique_constraint and value_type parameters cannot be updated.
They are set during the process of creating a custom field.


Updating choices


This endpoint also allows you to update the list of choices for a custom field with
single or multiple choices. For important details
regarding how this endpoint affects the list of available choices and how to avoid
creating duplicate choices, see the description of the choice body parameter.


This endpoint returns structured Custom Field objects.
As with all Kantata OX API endpoints, the returned data will be referenced in sorted order in the results array
and will be indexed by ID in the custom_fields top-level JSON key.
Please see our Response Format section for more information.


Request 
path Parameters
id
required
integer
The ID of the Model.


 
query Parameters
include
string
Any of the below associations can be included in your request by providing the include param, e.g. include=association1,association2.


    

  • choices (CustomFieldChoice) - Includes the ID of a Custom Field's choices.
    • 

  • creator (User) - Includes the ID of a Custom Field's creator.
    • 

  • custom_field_set (CustomFieldSet) - Includes the ID of the Custom Field Set that a field belongs to.
    • 

  • external_references (ExternalReference) - Includes references to external integrations for this object.
    • 



 
Request Body schema: application/json
required
object
 
name
string
The name of the field.


 
default_text
string
The message in an empty custom field, before a string, date, number, or currency  value is entered in.
This only appears in the UI.


 
Array of objects
The list of choices a user can select from,
for a custom field's value(s). Setting this field updates a custom field's 
complete list of choices; it behaves as an overwrite.
Include all existing choices in your request, whether you are updating their label or not.
Any choices not included in your request will be deleted from the custom field.


How to avoid creating duplicate choices


Choices have two attributes, a label and an ID. Different choices can have the same label,
but every choice has a unique ID. To properly update an existing choice within a list, you must specify the ID
of the choice you want to change. If you do not, a new choice with a unique, new ID is created instead.


For example:


custom_field_choices: {
  ....
  choices: [
    { "label": "Choice A", "id": "180291" },
    { "label": "Choice B", "id": "180301" },
    { "label": "Choice C" }
  ]
  ....
}



Choices in the UI appear in the same order as listed in the array.


The 1st choice is an existing choice with an ID of 180291, and is either staying or being updated to Choice A.
The 2nd choice is an existing choice with an ID of 180301, and is either staying or being updated to Choice B.
The 3rd choice is a new choice to create, Choice C, and its unique ID will be returned in the response.


 
custom_field_set_id
integer <int32> 
The ID of the Custom Field Set that the field belongs to.
When a set ID is not specified, the field is added to a Project set titled 'Default Project Set'.
This means it becomes a Project field.


 
write_access
string
The permission level required for a user to create, update, or delete a custom field value for a subject.


 
read_access
string
The read_access permission setting on each custom field
determines the minimum permission needed to view a custom field and its value.


    

  • Workspace (Project), Resource, and Story (Task) custom fields are project-specific objects,
so their minimum permissions are set at the project level:
      

    • project_collaboration (default)
      • 

    • time_logging
      • 

    • financial
      • 

    • project_admin
      • 

    

    • 



Most account-level permissions supercede project-level permissions. Therefore, Account Administrators
are able to view all Project, Resource, and Task custom fields and values across the account,
regardless of project participation or read_access settings.


    

  • Estimate, WorkspaceGroup (Group), and User custom fields are account-wide objects,
so their minimum permissions are set at the account level:
      

    • account_collaboration
      • 

    • project_creator
      • 

    • project_lead
      • 

    • reports_viewer
      • 

    • reports_viewer_with_cost
      • 

    • account_admin (default).
      •
