# Invoice Extraction

> Built-in workflow for extracting invoice fields into reviewable outputs.

## Overview

The `invoice-extraction` workflow starts from one or more `/v1/files` inputs, runs OkraPDF's built-in invoice processing pipeline, and returns run metadata plus JSON, CSV, XML, and XLSX export URLs.

Use this when you want an opinionated workflow instead of a one-off document question.
