# QR Code Webhook Setup in Zapier for OLC
Trigger an email notification (or Slack alert) when someone scans a QR code printed via Open Letter Connect. You’ll capture data via Zapier’s webhook and pull in UTMs.
#### What You’ll Need
✅ Access to Zapier account\
✅ Open Letter Connect account with webhook access\
✅ An email (Gmail/Outlook) Slack, or any messaging app for test notifications
### Step-by-Step Procedure
#### Step 1: Set up Webhook Trigger in Zapier
1. In Zapier, create a new Zap
2. Trigger App: Webhooks by Zapier
3. Trigger Event: Catch Hook
4. Copy the webhook URL Zapier provides\
5\. Paste that URL into Open Letter Connect
* Locate the “Webhooks” section (Settings > Webhook)
* Paste the Zapier webhook URL
* Select “QR Code Scans” on the Event Types
#### Step 2: Add Email Notification Step
1. Add a new Action step in Zapier:\
\
App: Email by Zapier (or use Gmail if preferred)
2. To: Your email
Subject: QR Code Scanned: {{utm\_firstname}} {{utm\_lastname}}
Body:\
A QR code was scanned!
\- First name: {{utm\_firstname}}
\- Last Name: {{utm\_lastname}}
\- Source: {{utm\_source}}
\- Time: {{data.scanned by contact last}}
{% hint style="info" %}
Note: If the UTMs aren't populating, check:
{% endhint %}
* If UTM parameters are added to your mail piece in Template builder.\
\
**Go to Templates > Select Template > QR Codes and input/map your UTMs**\
\
Step 3: Test in Slack
If you're using Slack instead of email:
1. Use Slack → Send Channel Message
2. Hook it up to your workspace and create a channel
3. Format the message with UTM fields. UTM fields can be found by clicking this:
#### Step 5: Publish
* Once tested, click Publish Zap
#### ❓ What are UTM Parameters?
UTM parameters are small tags added to the end of a website link (URL).\
They help you track where your visitors are coming from and what marketing piece they responded to — like a postcard, email, or text message.
Think of them as little labels that tell your analytics tool who clicked and from where.
#### Why You Should Use Them
Using UTM parameters lets you:
* Know which marketing campaigns work best
* Measure responses from postcards, emails, or QR codes
* Match visitors or leads back to your mailing list
* Save time when analyzing campaign performance
#### What a Link With UTM Looks Like
Regular website link:

With UTM parameters:

### Let’s Break It Down
| Parameter | What It Means | Example Value | Why It’s Useful |
| -------------------- | ---------------------------------------- | ------------------------- | -------------------------------------------- |
| utm\_source | The source — where the visitor came from | postcard, facebook, email | Shows which channel brought traffic |
| utm\_medium | The marketing type or channel | directmail, social, email | Groups results by campaign type |
| utm\_campaign | The campaign name | dental\_promo\_nov2025 | Helps identify which campaign they came from |
| utm\_firstname | The contact’s first name | John | Links response to your contact list |
| utm\_lastname | The contact’s last name | Doe | Same — helps match leads to data |
| utm\_address1 | The mailing address | 123\_Main\_St | Useful for matching mail recipients |
| utm\_propertyaddress | The property the mail piece refers to | 123\_Main\_St | Tracks multiple property campaigns |
#### How This Works in Practice
When you print a QR code on a dental campaign postcard, you can add UTM tags like these:
*
When Sarah scans her QR code, you’ll know:
* She came from the “postcard” campaign
* It was part of your “teeth\_whitening” campaign
* And you can match her visit to her mailing record in your dashboard
