The ICP every new person must pass before joining the list, from icp_list. Its ACTIVE version is the check, so revising the ICP changes future runs. Omit it or pass null for no ICP: then everyone the signals find is added. This is a full replacement, so on a list that HAS an ICP, omitting it removes the check — send back the icp.id source_get gave you to keep it. Six signals also SEARCH with the ICP and need one: lookalike, changed_jobs, posted_recently, company_raised_funds, company_leadership_change, company_hiring. Changing the ICP restarts those six from the top of their feed; the others keep their place.

Whether the source keeps feeding the list. paused stops it without losing anything — the signals, their places in their feeds, and every member already found all survive, and resuming carries on where it left off. Use this rather than source_delete to stop a list growing for a while. Omitted leaves the current setting; a new source starts active.

How many qualified people this list should gain per day (UTC), 1-1000. A floor, not a cap: every event signal still runs in full first, and the lookalike signal then keeps searching until the day's total reaches this number, the search runs out, 30 people in a row fail the ICP, or 20 companies (or result pages) in a row add nobody (it picks up from there the next day). Only the lookalike fills the gap, so on a source without one this only reports progress. Omitted leaves the current setting; a new source starts at 30.

How many people a walk that goes company by company takes at each company, 1-100. Applies to the lookalike (when the ICP describes companies) and to the recently-raised-funds and new-senior-leadership signals. Higher means fewer companies and less variety, but more of a big employer. Omitted leaves the current setting; a new source starts at 3.

Which workspace seat (a channel account id from seat_list) reads this list's SEAT signals: viewed_my_profile, recently_connected and company_followers, and any signal whose own search is measured from a seat (firstDegreeOnly, postedByMe, postedByFollowed or inYourNetwork in its config, or a networkDistance-style filter in the ICP). Every other signal reads on Kairon's own accounts and needs no seat. Any member may pick any connected seat. Omitted: the list keeps its seat, else takes yours if it can run them; if neither works the call is refused with SOURCE_SEAT_REQUIRED, which lists the seats that can. Refused with SOURCE_SEAT_CANNOT_RUN when the seat lacks what a signal needs (a paid licence for viewed_my_profile, page admin for company_followers, Sales Navigator for a viewer-relative ICP). Ignored when no signal needs a seat.

The workspace's plan includes a number of growing lists (lists whose source is active). Turning a list on past that number costs the plan's price for an extra list, every month, billed to the organization; on a plan that sells none it is refused. A call that turns a list on past the included number is REFUSED unless this is true, and the refusal carries the price: ask the user first, then retry with it. Ignored when the call turns no list on, or the list fits. A list carries at most 3 signals.
