  method: 'POST',
  headers: {
    'Authorization': 'Bearer sk_live_...',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    name: 'Contract.pdf',
    file_url: 'https://example.com/contract.pdf',
    signers: [{ email: 'john@example.com' }]
  })
});

Get Document Status

const response = await fetch('https://api.liftsign.com/v1/documents/doc_123', {

const document = await response.json();
console.log(document.status); // 'pending' | 'signed' | 'completed'
