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());
