# Upload a CSV to start a bulk import

`POST /v1/invoices/imports`

Starts a bulk invoice import. The request is `multipart/form-data` with a single required `file` part carrying the CSV (max 5 MiB, up to 1000 rows), e.g. `curl -F "file=@july-invoices.csv"`. The response carries the new batch plus the detected column headers for the mapping step and a duplicate-upload warning. (The file part is described here rather than as a schema: the swag pipeline cannot attach the §10-required example to a binary multipart property.)
