Bring Your Own UI

Your Frontend → Your Backend → Forme API → PDF result

// Your frontend collects redaction regions from user interaction
const regions = [
  { page: 0, x: 100, y: 200, width: 150, height: 20 },
  { page: 0, x: 300, y: 400, width: 200, height: 15 },

// Your backend sends them to Forme

  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.FORME_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    pdf: pdfBase64,
    redactions: regions,
  }),
});

const redactedPdf = Buffer.from(await res.arrayBuffer());

// User selected these PDFs in your UI

// After user approves the document in your UI
