# Import sessions

> Bulk-import sessions (contacts). The body must be `{ "sessions": [...] }`. Every entry is matched
against an existing contact before anything is created — by `userId` when the row carries one,
otherwise by `email` — so importing the same list twice updates those contacts instead of
duplicating them. Returns the ids of the imported sessions.

At most `MAX_IMPORT_SESSIONS_PER_REQUEST` rows per call: a request has to finish well inside the
edge's 60s window, and a larger list belongs in a sequence of these calls. Oversized bodies are
rejected rather than truncated.
