Object types
Every list is homogeneous — it holds a single type of object, described by itsobjectType:
COMPANY— companiesLEGAL_ENTITY— legal entitiesCONTACT— contacts (a contact is always tied to a company)
objectType determines the shape of the items returned by the results endpoint and
the shape accepted when adding items.
Identifiers
List IDs (listId) are obfuscated. You obtain them from the overview
endpoint and pass them back to the other endpoints.
Authorization
The Public API token is team-scoped. Every request only operates on lists that belong to your team; requesting a list from another team returns404.
