Each page below documents a single event source operation — request, parameters, response shape, and errors. Event sources are the configuration layer that registers where outcome and marketing events come from (pixels, SDKs, warehouse syncs, CRM feeds, MMPs); log-event is the runtime path that sends per-user events keyed to a registered source. Sync a source once, then log events through it. For the full picture, see the Log Events guide. To use a source in a conversion goal on a seller account such as Meta or Snap, map it to that account’s pixel or dataset: see Use your event sources and audiences on each seller account.
