Trigger Your n8n Workflow with a No-Code Camera Scanner in 5 Minutes

Most n8n workflows start from a file that’s already been uploaded somewhere — a form, an email, or a shared drive. But what if your workflow could start the moment a document is scanned — directly from a phone camera, no app installation required?

That’s exactly what ScanKit’s Instant Scanners make possible.

In a few minutes, you’ll connect a simple web-based scanner to your n8n workflow so that every scan automatically triggers your automation — from any mobile browser.

What You’ll Build

You’ll create a camera scanner that:

• Works directly in a smartphone browser (no app needed)
• Scans and crops documents automatically
• Sends results straight into an n8n workflow
• Can be opened via link or QR code

By the end, you’ll have a working, shareable scanner that starts your n8n process with a single photo.

Prerequisites

• A ScanKit.io account (free tier works fine)
• An n8n instance (cloud or self-hosted)
• About 5 minutes of setup time

---

Step 1 — Create Your Instant Scanner

Go to your ScanKit Dashboard and open Instant Scanners.

1. Click Create New Scanner and name it n8n Scanner
2. (Optional) Add a description like “Scans documents directly into n8n”
3. Pick a brand color and upload your logo if you like
4. Leave the Webhook URL field empty for now — we’ll come back to it

Your scanner preview will update as you type. When you’re ready, click Create.

💡 Pro tip: If you already have an n8n webhook URL ready, you can start there and paste it directly while creating the scanner. The order doesn’t matter — both paths work.

---

Step 2 — Create and Configure the Webhook in n8n

Open your n8n dashboard and create a new workflow.

1. Add a Webhook node and configure it:
   • Method: POST
   • Path: something simple, e.g. scankit-upload
   • Response Mode: Respond immediately
2. In the same node, add this domain under Allowed Origins (CORS):

   https://www.scankit.io
   

   This allows your workflow to safely receive document uploads from your hosted scanner.
3. Save and activate your workflow.
4. Copy the Test or Production Webhook URL — you’ll use it in the next step.

---

Step 3 — Connect the Webhook to Your Scanner

Back in your ScanKit Dashboard:

1. Open your newly created scanner
2. In the Webhook URL field, paste the n8n webhook URL
3. Click Update

Your scanner is now linked to your workflow.

---

Step 4 — Test the Scanner

1. Click Share Scanner to open it on your phone or copy its QR code
2. Use your phone’s camera to scan a document
3. The scanner automatically crops and sends it to n8n

Within seconds, you’ll see the Webhook node trigger — confirming that everything works.

What You Can Build

Once connected, every scan from your scanner sends a PDF with an embedded OCR text layer directly to n8n. You can use n8n’s built-in Extract from File node to read the text from the PDF and process it further — no extra OCR step required.

Here are some examples:

• Invoices: Scan → Extract text → Categorize or upload to accounting system
• Receipts: Scan → Parse totals → Append to Google Sheets
• Contracts: Scan → Let an LLM summarize or classify content → Store in Drive
• Forms: Scan → Extract fields → Add to CRM or database

This turns document scanning into a fully text-aware entry point for your workflows.

Every scan flows in here — what happens next is yours to create.

---

Example — From Receipt to Google Sheets

A simple workflow might look like this:

1. Webhook — Receives the scanned PDF from ScanKit
2. Extract from File — Extracts OCR text automatically
3. Code or AI Node — Parses date, amount, or vendor name
4. Google Sheets — Adds a new row with extracted data

That’s a complete, end-to-end automation — powered by one scanner link.

Wrapping Up

You’ve just connected ScanKit and n8n to create a fully no-code document intake flow.

Every scan now starts an automation — from a link or QR code, on any device.
