html_url	string	true	false	The url of this category in Help Center
id	integer	true	true	Automatically assigned when creating categories
locale	string	false	true	The locale where the category is displayed
name	string	false	true	The name of the category
outdated	boolean	true	false	Whether the category is out of date
position	integer	false	false	The position of this category relative to other categories
source_locale	string	true	false	The source (default) locale of the category
updated_at	string	true	false	The time at which the category was last updated

  "locale": "en-us",
  "name": "Self Help Articles",
  "source_locale": "en-us",

}

List Categories

• GET /api/v2/help_center/{locale}/categories
• GET /api/v2/help_center/categories

Note: {/locale} is an optional parameter for admins and agents. End users and anonymous users must provide the parameter.

Allowed for

• Anonymous users

The response will list only the categories that the agent, end user, or anonymous user can view in the help center.

Pagination

• Cursor pagination (recommended)
• Offset pagination

See Pagination.

Sorting

You can sort the results with the sort_by and sort_order query string parameters.

GET /api/v2/help_center/en-us/categories.json?sort_by=updated_at&sort_order=asc

The sort_by parameter can have one of the following values:

value	description
position	order set manually using the Arrange Content page. Default order
created_at	order by creation time
updated_at	order by update time

The sort_order parameter can have one of the following values:

value	description
asc	ascending order
desc	descending order

Sideloads

The following sideloads are supported:

Name	Will sideload
translations	the category translations, if any

Translations are embedded within the category because they're not shared between resources.

Parameters

Name	Type	In	Required	Description
sort_by	string	Query	false	Sorts the results by one of the accepted values. Allowed values are "position", "created_at", or "updated_at".
sort_order	string	Query	false	Selects the order of the results. Allowed values are "asc", or "desc".
