Advertising & Analytics Pixels
Retarget scanners and measure QR performance inside the ad platforms you already use.
Meta Pixel
Pro+Fires a PageView event on every scan for Facebook & Instagram retargeting and Lookalike audiences.
Google Ads
Pro+Track scans as conversions and build retargeting audiences via a Conversion ID (AW-XXXXXXXXX).
Google Analytics 4
Pro+Send every scan into GA4 as a page_view via your Measurement ID — shares one gtag.js loader with Google Ads.
LinkedIn Insight Tag
Pro+Fire LinkedIn's automatic page-view event on scan for B2B retargeting via your Partner ID.
Microsoft Ads (UET Tag)
Pro+Fire the UET tag's automatic pageLoad event on every scan for Microsoft Ads retargeting via your Tag ID.
Audience & Lead Sync
Move consented Lead Hub contacts into the platforms you run campaigns from.
Meta Custom Audiences
Pro+Push consented Lead Hub contacts into a Meta Custom Audience inside your own ad account, then build a Lookalike to reach more people like them.
Your Own Sending Domain
Pro+Verify your own domain and send branded email campaigns to Lead Hub contacts — no third-party branding in the From address.
Developer
Automate QR management from your own systems.
Automation
React to a scan, QR change, or redirect rule the instant it happens — via your own endpoint, Slack, or Zapier.
Webhooks
Pro+Register a URL and SMLLR POSTs a signed JSON payload to it — QR created/updated, scans, and redirect rules — in real time instead of polling.
Slack
Pro+Paste a Slack Incoming Webhook URL and get QR/scan notifications posted straight to a channel — no app install or OAuth required.
Zapier
Pro+Paste your SMLLR webhook URL into Zapier's Catch Hook trigger to connect 6,000+ apps — no code required.
How Pixels Fire On Scan
One account-wide default, with per-QR overrides when a specific code needs to report differently.
Set Account Defaults
Add your Meta Pixel ID, Google Ads Conversion ID, GA4 Measurement ID, and LinkedIn Partner ID once, under Settings → Tracking Pixels.
Override Per QR Code
Every QR code inherits the account default automatically — override just the platforms you need to differ, on a single QR code, without touching the rest.
Fires On Every Scan
SMLLR injects the right script into the redirect page a scanner briefly lands on, so each scan reports back to your ad accounts like a real page view.
Note: QR codes whose destination is tel:, sms:, or mailto: redirect directly with no intermediate page, so pixels only fire for http(s) destinations.
