There are multiple ways you can already accomplish this:

#Path 1:

-Create a trigger link

-Map that trigger link to the URL parameter in the QR code.

-[optionally] create a URL forwarder to a shortening domain to make the QR code more legible, and use the bit.ly or otherwise URL shortener link with the target value being the trigger link.

-Create your automation workflow trigger as the trigger link being clicked.

#Path 2:

-Pass in URL input parameters (such as tags or UTM) from the URL path in the QR code.

-Set the workflow trigger to be contact tag added/updated, etc

-[optionally] create a URL forwarder in GHL to a shortening domain link to make the QR code shorter by use of bit.ly or other URL shortener domain link with the target value being the entire trigger link.

(e.g. "https://marketsuite.io/demo-page?phone=5551234567&service=SEO&utm_source=fb > "URL Redirects" > 'https://bit.ly/U7e9jt3' > generate QR Code URL == bitly link )

#Path 3:

-If using a complex automation via middleware such as N8n, Make, or Zapier, generate a web hook and then have the trigger event for the workflow be the web hook.

#NOTE:

** use of 'bit.ly' or other URL shortener domain service OR just buy your own short domain name and import it into the GHL agency "domains' for use across multiple sub-accounts. (allows for more easily scanned QR Code based on better QR Code 'version' and 'error correction' settings and less data to render in the dot-matrix.) [Reasoning: the shorter the URL, the easier the QR Code is to scan.]

Hope that helps!

I think this would help move the needle on our needs. We want to provide a customer with a biz card / post card which introduces our referral program. They can share the card with a friend or neighbor - the friend scans the qr code and it triggers an automation linked back to our customer so we now who referred them.

Make a QR also act like a Trigger Link. Whatever the Contact sends via the QR is included in the Contact record which then allows a Workflow to follow up (send an email back with the promised lead magnet!) and assign to a user.

If a QR code is scanned an automation ie. such as inputs a keyword into an SMS messenger. Many QR code generators can do this today. Then the person can on their mobile device press send to opt-in to a particular campaign.
