# Async bulk contact import

`POST /v1/contacts/bulk`

- Authentication: required (Bearer token)
- Required scope: `api.contacts.manage`

Submits a batch of up to 5 000 contacts for asynchronous upsert.
The endpoint returns immediately with a job id and `202 Accepted`;
poll `GET /v1/contacts/bulk/{job_id}` until `status` is `completed`
or `failed`.

Each row is processed independently — a single row's validation
failure (unknown attribute, bad email) marks that row `failed` while
the rest of the batch continues.  The overall job never returns `failed`
due to per-row errors.

Supports the `Idempotency-Key` header: a duplicate key within 24 h
replays the original 202.
