# Import sessions

`POST https://api.gleap.io/v3/sessions/importer`

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.

## Authorization

- `Authorization` (header, required): `Bearer <token>`

## Headers

- `project` (string, required)

## Request body (`application/json`, required)
