SnapPDF + Dropbox

What you can build

• Right-click Dropbox Extension for all 15 ops.
• File Request auto-compress: any PDF over threshold is shrunk on arrival.
• Dropbox Paper integration: attach a PDF to a Paper doc → action SnapPDF in the side panel.
• Folder-watched triggers, same model as Drive.
• Business + Enterprise Dropbox: run ops under a team admin account.

Setup

1. 01
   Install the Dropbox Extension

   Dropbox App Center → search "SnapPDF" → Install. Personal and Business workspaces both supported.
2. 02
   Authorize and link

   OAuth flow grants SnapPDF `sharing.read` and `files.content.write` on the folders you pick. No global Dropbox access.
3. 03
   Set up a file-request rule

   SnapPDF dashboard → Integrations → Dropbox → File Request Rules. Point at a File Request link, set op (compress), set threshold (e.g. 25MB).
4. 04
   Try a right-click op

   Right-click any PDF in Dropbox → Open with... → SnapPDF. Pick op, hit Run. Output appears alongside the original.
5. 05
   Configure folder watch (optional)

   Same dashboard, File Watches section. Picks up new files every 60s.

Code example

Dropbox webhook → SnapPDF compress if > 25MB. Illustrates the underlying flow the integration wraps.

// Dropbox webhook fires on file change
app.post('/dropbox-webhook', async (req, res) => {
  res.status(200).end(); // ack immediately
  const changes = await dropbox.filesListFolderContinue({ cursor: req.body.cursor });

  for (const entry of changes.result.entries) {
    if (!entry.name.endsWith('.pdf')) continue;
    if (entry.size < 25 * 1024 * 1024) continue;

    const { result } = await dropbox.filesDownload({ path: entry.path_lower });
    const compressed = await snap.pdf.compress({
      file: result.fileBinary,
      level: 'high',
      stripMetadata: true,
    });

    await dropbox.filesUpload({
      path: entry.path_lower,
      contents: compressed.pdf,
      mode: { '.tag': 'overwrite' },
    });
  }
});
