## Run it

Ask an AI agent connected to Reduck over MCP (`https://mcp.reduck.ai/mcp`) to run `reduck/admin.atlassian.com/download_invoice`, or run it from a terminal:

```bash
npx @reduck-ai/cli@latest run --script reduck/admin.atlassian.com/download_invoice
```

## Input

- `id` (string, optional): Atlassian invoice id from admin.atlassian.com/list_invoices. Used only when downloadUrl is not given, and then transaction_account is required too.
- `number` (string, optional): The invoice's number from the list row (e.g. IN-EU-002-392-813). Optional, and only used to name the file: Atlassian's download endpoint sends no Content-Disposition, so without this the filename falls back to the opaque invoice id.
- `downloadUrl` (string, optional): The invoice's downloadUrl exactly as returned by admin.atlassian.com/list_invoices. Preferred over id/transaction_account.
- `sourceSystem` (string, optional): Which billing system issued the invoice, from the list row. Only used when building the URL from id.
- `transaction_account` (string, optional): The invoice's transaction_account from the list row. Required when using id instead of downloadUrl.

## Output

- `filename` (string, required): The real suggested filename from the file's Content-Disposition, falling back to Atlassian-<id>.pdf.
- `pdf_base64` (string, required): The PDF bytes, base64-encoded. Decode and write it yourself — the script is sandboxed and cannot write to disk.
- `via` (string, optional): Which route produced the bytes: a direct same-origin fetch of the billing endpoint, or a second fetch after landing on the storage host Atlassian redirected the file to. Diagnostic only.
- `size_bytes` (integer, optional): Byte length of the decoded PDF.
