Headless flow-execution API for iX Hello Customer v2. Starts a stateful conversational session against an authored flow, sends user turns into it, reads accumulated session variables, and terminates the session — all over REST, with no chat or voice front end attached. Injects context variables at session start, returns the flow's messages and wait state on every turn, and correlates back to the caller's own system through an opaque metadata block. Organization-scoped bearer API keys; sessions live at most one hour.
