Body
List data
Request body for creating a new smart list. Sharing visibility is controlled by listDict.sharing — see field description for the three modes.
List properties. Required: name (string). Optional: type (string, one of "leads" | "companies" | "custom"; default "custom"), sharing (string controlling visibility — see below; default "Private"), fields (object of column definitions, only when not using a template), templateId (string, when creating from a template).
sharing values:
- "Private" (default): only the creating user can view or modify the list.
- "Shared": any user in the same company can view and modify the list.
- "Public": anyone with the list ID can read the list and its rows via the public endpoints (GET /public/lists/ and GET /public/lists//rows). Only the list owner can change sharing afterward.
departmentIds (array of department ID strings, optional): only applies when sharing is "Shared". When set, only company members assigned to one of these departments (plus admins/owners and the list owner) can see the list. Leave empty/omitted for no department restriction. Also drives the folder grouping in the UI.
Company ID that owns the list. Required when authenticating with a personal access key (pak_…) — the key is not tied to a specific company so the server cannot infer it. Required when authenticating with a company API key only if the key belongs to a user who has access to multiple companies; otherwise it defaults to the key's company. Optional for JWT (dashboard) auth — defaults to the user's active company.
Response
Newly-created list (id and name)
Response returned after creating a list. Includes the list's column headers so callers know the exact column names/types to read or write rows against — no follow-up request is needed.
