Import a historical conversation
Create one historical conversation and all supplied messages atomically. Requires cxm:conversations.write. References an existing contact (or anonymous) and optional existing organization, without updating either. No messages, AI turns, routing or notifications are activated during import. Waits for one search-indexing attempt after commit. Indexing failure returns 201 with the created ID and IndexingFailed; an existing projection returns IndexingConflict without replacing it. A known disabled indexer rejects with 503 before creation. There is no append, merge, upsert or transcript continuation. Import shares the conversation-write rate group. Search may retain only the latest 500 messages and public history applies size/redaction limits, so neither is a lossless export verifier. Requires the matching tenant API-key write scope or broader scope. Maximum JSON request body: 1 MiB, subject to a lower configured gateway limit. Unknown fields are rejected. Each accepted request executes; no idempotency or replay guarantee. A timeout may occur after commit.
