Data lists store reusable sets of key-value options used in custom fields — for example, the choices in a dropdown, checkbox group, or radio button set. Manage both the lists themselves and their individual items.

​
What you can do

  • Create and manage data lists that define sets of options
  • Add, update, and remove items within a data list
  • Reuse lists across fields — one data list can power multiple custom fields

Key concepts

List and items — A data list is a container. Data list items are the individual options (e.g., “Option A”, “Option B”) within that container. Use the Data List Items endpoints to manage the options. Reusability — A single data list can be referenced by multiple custom fields across different resource types, keeping your option sets consistent.
