Invoice OCR API

Not a developer? If you want invoice OCR software with a UI (no code), see Invoice OCR for accuracy benchmarks and screenshots, or Invoice Automation Software for the full AP workflow. This page is the developer REST API reference.

Extract structured data from invoice PDFs: vendor, line items, totals, and dates. Output is JSON or CSV for accounting systems and expense tools.

Full example (no SDK)

Complete flow using only HTTP and JSON: upload → create job (jobType: Invoice) → poll → export.

javascript

const fs = require('fs');
const BASE = 'https://www.docuclipper.com/api/v1';
const API_KEY = process.env.DOCUCLIPPER_API_KEY;
const auth = (h = {}) => ({ Authorization: `Bearer ${API_KEY}`, ...h });

const form = new FormData();
form.append('document', new Blob([fs.readFileSync('invoice.pdf')]), 'invoice.pdf');
const up = await fetch(`${BASE}/protected/document`, { method: 'POST', headers: auth(), body: form });
const docId = (await up.json()).document.id;

const job = await fetch(`${BASE}/protected/job`, {
  method: 'POST', headers: auth({ 'Content-Type': 'application/json' }),
  body: JSON.stringify({ jobName: '', documents: [docId], jobType: 'Invoice' })
});
const jobId = (await job.json()).id;

let status;
while ((status = (await fetch(`${BASE}/protected/job/${jobId}`, { headers: auth() }).then(r => r.json())).status) !== 'Succeeded') {
  if (status === 'Failed') throw new Error('Job failed');
  await new Promise(r => setTimeout(r, 2000));
}

const exp = await fetch(`${BASE}/protected/job/${jobId}/export`, {
  method: 'POST', headers: auth({ 'Content-Type': 'application/json' }),
  body: JSON.stringify({ jobType: 'Invoice', flattenTables: true, format: 'json' })
});
console.log(await exp.json());
