Churnkey Reactivation API
Reactivation (win-back) campaigns that re-engage churned or paused customers with targeted offers. Reactivations are a documented Churnkey product, but a dedicated public REST endpoint set is not published; campaigns are configured in the Churnkey dashboard and driven by the same customer/event data surfaced through the Event Tracking and Data APIs. Endpoints here are modeled, not confirmed from public reference documentation.
