Lists

Using the CLI?

The CLI supports g8 create-list, g8 add-to-list, and g8 build-list (search + save in one step).

Lists organize contacts into groups for campaigns, exports, and segmentation.

Lists are also how data moves from the open data index into your workspace. When you call /search/contacts/save or /search/companies/save, graph8 creates a new list and populates it with matching records. Those contacts and companies then become part of your first-party data, accessible through the /contacts and /companies endpoints.
