Setting Up the Open Letter Connect Webhook in GoHighLevel to Track QR Code Scans

Connect OLC with your GHL account so every time someone scans one of your QR codes, it automatically updates your GoHighLevel workflows letting you tag contacts, send follow-ups, or record the scan event.

What You’ll Need

✅ An Open Letter Connect account ✅ A GoHighLevel account (with Automation / Workflow access) ✅ A few minutes to copy and paste one webhook URL ✅ Open Letter Connect App downloaded in your GHL Marketplace

Step 1: Create the Inbound Webhook in GHL

1. Log in to GoHighLevel.

2. Go to Automations → Workflows.

3. Click Create Workflow → Start from Scratch.

4. Create a name for your workflow like “QR Scan from OLC.”

5. Add a Trigger → Inbound Webhook.

6. Copy the Webhook URL GHL generates (you’ll paste this into OLC).

7. Leave the workflow inactive for now—we’ll turn it on after testing.

Step 2: Add the Webhook in Open Letter Connect

1. Log in to Open Letter Connect.

2. Navigate to Settings → Webhooks.

3. Click Create New Webhook.

4. Fill out the form:

5. Webhook URL: Paste the URL you copied from GHL.

6. Event: Select QR Code Scans - order_item.qr_code_scanned

7. Click Save.

   

   

Step 3: Test Your Connection

1. In OLC, Go to Webhooks.

2. Click “Test Webhook”.

3. Back in GHL, return to your new workflow and click Fetch Sample Request.

4. GHL will display the sample data sent from OLC.

   

Step 4: Map and Automate

Once the payload loads, add actions in your workflow—for example:

• Update Contact → Tag: “QR Scanned”

• Send Internal Notification: “John Doe just scanned a QR code!”

• Add to Campaign: “Post-Scan Follow-Up”

Then, Publish / Activate the workflow.
