SnapPDF + SignBolt

What you can build

• Direct PDF handoff — no re-upload, no S3 roundtrip.
• Pre-fill signature field coordinates from SnapPDF's sign op placeholder mode.
• Merged audit trail: prep events (SnapPDF) + signing events (SignBolt) in one timeline.
• Shared billing — one subscription covers both products at the Enterprise tier.
• Shared key model — a single key with `pdf:*` + `sign:*` scopes works across both APIs.

Setup

1. 01
   Create a SignBolt account

   signbolt.au — same email works if you already have SnapPDF.
2. 02
   Link accounts

   SnapPDF dashboard → Integrations → SignBolt → Link account. OAuth handshake, 20 seconds.
3. 03
   Create an Enterprise key (optional)

   For combined scopes, create a key scoped `pdf:write` + `sign:write`. Works on both APIs.
4. 04
   Use the handoff endpoint

   After a SnapPDF op, call `POST /api/v1/signbolt/handoff` with the PDF reference and recipient list.
5. 05
   Poll or webhook for completion

   SignBolt fires webhooks back to your endpoint when signing completes; audit events land in the merged trail.

Code example

Prep contract in SnapPDF, hand off to SignBolt in one chain.

// Step 1: SnapPDF prep
const { pdf: merged } = await snap.pdf.merge({
  files: [contractPdf, addendumPdf],
});
const { pdf: filled } = await snap.pdf.fillForm({
  file: merged,
  values: { client_name: deal.clientName, deal_value: deal.valueLabel },
  flatten: false,
});

// Step 2: Hand off to SignBolt
const envelope = await fetch('https://api.snappdf.dev/api/v1/signbolt/handoff', {
  method: 'POST',
  headers: { Authorization: 'Bearer ' + key, 'Content-Type': 'application/json' },
  body: JSON.stringify({
    file: filled.pdf,
    recipients: [
      { email: 'ceo@acme.com', name: 'Jane Smith', role: 'signer' },
      { email: 'cfo@us.com', name: 'Bob Jones', role: 'counter_signer' },
    ],
    subject: 'Master Services Agreement — please sign',
    expiresInDays: 14,
  }),
}).then(r => r.json());

console.log('SignBolt envelope:', envelope.id);
