# Add evidence files to a back work bookkeeping program

`POST /tally/programs/backwork-bookkeeping/{id}/files`

## Request

- Base URL: `https://ledgerhq.pro/api/v1`
- URL: `https://ledgerhq.pro/api/v1/tally/programs/backwork-bookkeeping/{id}/files`
- Auth: one of:
  - HTTP bearer and API key in header `x-organization-id`
  - HTTP bearer and API key in header `x-organization-id`

Requires firm owner/admin accounting authority. Accepts either multipart uploads (up to 50 CSV/XLSX/ZIP files, 50 MB) under the `files` field, or JSON with workspacePaths and/or evidenceIds (1–50 total) to load existing workspace files or chat attachments into program intake. Saves each file best-effort with collision-safe names, safely expands ZIP archives, always rescans files saved before any later failure, and returns both per-file outcomes and the refreshed account-by-month scan. ZIP containers remain stored for replay but are omitted from visible evidence counts. Clean scans do not auto-start pre-flight; call Begin Import when the firm is done adding files.

## Path parameters

- `id` string, uuid, required

## Request body

- object
  - `workspacePaths` string[]
  - `evidenceIds` string[]

## Response `200`

Per-file saved/failed outcomes and refreshed intake scan report

## Other responses

- `409`: The Back work program has an import receipt or is terminal; ordinary recoding remains available.
- `default`: Error response
