# List client data lists

GET https://api.yunojuno.com/client_data_lists/

List the client data lists available to your account.

Return the set of data lists available to your client account. Client data lists back dropdowns and validations across YunoJuno (e.g. departments, cost centres). This endpoint enumerates which lists you can manage via the API; it does not return the full list contents.
