SnapPDF + Notion

What you can build

• Run ops on any Notion file-block PDF.
• Database trigger: when a row's status hits "Ready to Ship", auto-merge attached PDFs into one.
• Writes the result back to the page as a new file block (doesn't replace the original).
• Cover-page generation from page properties (title, author, date).
• Limited by Notion's own 5MB file upload cap — compressed outputs only.

Setup

1. 01
   Create a Notion Integration

   notion.so/my-integrations → New Integration → name it "SnapPDF" → internal integration. Copy the token.
2. 02
   Share pages with the integration

   On each page/database you want to process: Share → Add connections → pick SnapPDF. Only shared pages are visible to the integration.
3. 03
   Link from SnapPDF dashboard

   Dashboard → Integrations → Notion → paste the token. Test connection.
4. 04
   Action a block

   In Notion, click the meatball menu on a file block → Apps → SnapPDF → pick op.
5. 05
   Set up database automation (optional)

   SnapPDF dashboard → Notion → Database Triggers. Pick the database, a property change to watch, and an op to run.

Code example

Underlying API flow: Notion webhook → SnapPDF merge → write new block.

app.post('/notion-webhook', async (req, res) => {
  const { page_id, property } = req.body;
  if (property.name !== 'Status' || property.value !== 'Ready') return res.status(200).end();

  const page = await notion.pages.retrieve({ page_id });
  const blocks = await notion.blocks.children.list({ block_id: page_id });
  const pdfBlocks = blocks.results.filter(b => b.type === 'file' && b.file.file.url.endsWith('.pdf'));

  const { pdf } = await snap.pdf.merge({
    files: pdfBlocks.map(b => b.file.file.url),
  });

  const upload = await uploadToNotionFileService(pdf);
  await notion.blocks.children.append({
    block_id: page_id,
    children: [{ type: 'file', file: { type: 'external', external: { url: upload.url } } }],
  });

  res.status(200).end();
});
