# Bulk create/update catalog entries (async)

`POST /catalog/entries/bulk`

Creates or updates multiple catalog entries asynchronously. Returns 202 with batch tracking info. Maximum 1000 entries per request. Poll GET /batch/{id}/progress for status.

**Deprecation notice:** The previous synchronous bulk API has been deprecated. This async endpoint is the recommended behavior going forward — it avoids timeouts on large batches and provides progress tracking via the batch polling API.

## Headers

- `Authorization` string, required
- `X-Api-Key` string, required
