Run restaurant promotions with Zapier and single-use vouchers
Send, track, and redeem offers in the real world. Each customer gets a unique voucher. Staff validate it at the table with a phone scan. No POS integration needed.
What breaks when you use Zapier for restaurant promotions
Most Zapier coupon setups have the same problem: the code gets sent, but nothing controls what happens after that.
You paste "LUNCH20" into a Zap, and every customer who triggers it gets the same code. That code ends up in group chats, on deal sites, and in the hands of people who were never part of your campaign. You have no way to tell which redemptions were real.
Even if you use a list of unique codes, Zapier alone can't tell you whether a code was actually redeemed. It can't stop someone from using a screenshot. It can't give your staff a way to check if the person standing at the counter has a valid offer or a forwarded one. And if the Zap fires twice for the same customer, they get two codes. There's no deduplication and no audit trail.
The result: you're running a promotion you can't measure, and leaking margin you can't see.
How Coupon Carrier fixes this
Coupon Carrier sits between Zapier and your customer. When a Zap fires, Coupon Carrier generates a unique Redeem Link for that person. The link opens a personal voucher page with a QR code and a "Mark as Used" button.
At the restaurant, the customer shows the voucher on their phone. Your server opens the Coupon Carrier scanner in any mobile browser, points it at the QR code, and gets a clear answer: green for valid, red for already used, gray for invalid. One tap and the code locks. It can never be used again.
Every redemption is logged with a timestamp. You can see exactly who got a code, when they used it, and where. If you have multiple locations, they all validate against the same system. A code redeemed at your downtown location is instantly locked at every other one.
How the workflow runs
A customer signs up through a QR code on your table tent or a form on your website. That triggers a Zap. Coupon Carrier sends the voucher. The customer comes back and redeems it.
Real-world restaurant examples
Table tent QR signup
Print a QR code on table tents. A customer scans it, enters their email, and Zapier sends them a voucher for a free drink on their next visit. When they come back, the server scans the QR on their phone. Green means go. The voucher locks after one use.
Weekend email promotion
Every Friday, send a weekend deal to your subscribers. Instead of blasting one discount code to everyone, Coupon Carrier assigns a unique code per person. Each one works once. You see exactly how many people walked in and redeemed, not just how many opened the email.
Flyer QR at the door
Stick a QR code on a flyer outside your restaurant. It links to a signup form offering 15% off. When someone fills it out, Zapier sends a unique voucher. They walk in, show it to staff, and it gets validated on the spot. The code can't be reused or forwarded.
Why Zapier alone is not enough
Zapier is good at moving data between apps. When something happens in one app, it can trigger an action in another. That part works.
But Zapier has no concept of redemption. It cannot prevent a code from being used twice. It cannot give your staff a way to validate a voucher at the counter. It cannot tell you whether a promotion was redeemed at Location A or Location B. And it cannot lock a code after first use.
If your promotion ends at "send a code by email," Zapier is fine. If the code needs to be validated in person, you need a redemption layer. That's what Coupon Carrier adds.
