# Download an evidence file

Source: https://checkslip.com/en/docs/download-evidence-export

GET `https://api.checkslip.com/api/audit/exports/{export_id}/file`

API key

The evidence file as NDJSON, one record per line, ordered by day. The last line is the manifest; its sha256 covers every byte before that line and is also sent in the Repr-Digest header. Not READY yet answers 409; after expires_at it answers 410 and you request a new file. Every download is written to the account activity. Uses no credit. Needs an API key with both audit:read and audit:export, or the web app sign-in.

## Parameters

| Field | In | Type | Required |
