Create a new journey. Defaults to DRAFT state. Send nodes are not allowed on create — create the shell with a trigger node, then call replace_journey to add send nodes after linking notification templates. Call publish_journey to make it live. Node ids are server-generated; do NOT include an id field. Example: { name: "Welcome Journey", nodes: [{ type: "trigger", trigger_type: "api-invoke" }], enabled: true }.
