Zapier connects thousands of web apps so you can build automations without code. When you connect Coupon Carrier to Zapier, you can deliver unique, single-use coupon codes from virtually any app in your marketing and sales stack.
This guide will provide a complete, step-by-step walkthrough of how to connect Coupon Carrier and Zapier. We'll cover the essential setup steps in both platforms and then build a practical, real-world example: automatically sending a unique "thank you" code to a respondent after they complete a Typeform survey.
Before you can build your Zap, you need two things from your Coupon Carrier account: your API Key and a "Zapier-triggered" configuration.
Your API key is how Zapier securely authenticates with your account. You can find it by navigating to your account dropdown menu and clicking on API Key.

Next, create the specific email campaign you want Zapier to trigger. Go to Configurations > Create a New Configuration and select Code Email. For the trigger, choose Zapier Trigger. Customize the email content and connect it to a code list, then save and activate it. You'll select this configuration by name later in Zapier.

For this guide, we'll build a Zap that automatically sends a unique coupon code when someone submits a form in Typeform. You can use this same logic for any of the 8,000+ apps on Zapier.
In the Zapier editor, your first step is the Trigger. Search for and select your trigger app (in this case, Typeform). Choose the event that should start the workflow, such as "New Entry." Connect your account and select the specific form you want to monitor. Zapier will then test the trigger to pull in sample data.
Now, add your second step: the Action. Search for and select Coupon Carrier. You will see a list of available actions you can perform. For this workflow, choose "Send a Code Email."

This is where you connect the data from your trigger to your action. You'll see several fields:

Once your fields are mapped, Zapier will allow you to test the step. This will send a real request to Coupon Carrier and deliver a real email to the sample email address from your trigger. After a successful test, you're ready to name and publish your Zap!
Sending an email is just the beginning. You can also use other Coupon Carrier actions in Zapier to build more advanced workflows:
Many of these codes end up being redeemed in person — at a store, restaurant, or event. If your campaign includes an in-store component, see how to run an in-store promotion without POS integration for the redemption side of things.
Zapier can also power the delivery side of in-person promotions. The pattern is the same: a trigger fires, Coupon Carrier generates a unique voucher, and the customer redeems it at a physical location.
At the store or event, the customer shows the voucher on their phone. Staff tap "Mark as Used" or scan the QR code with the web-based scanner on their own phone. The code locks and can't be reused. Every Redeem Link includes a QR code, so scanning works at a counter, table, or door.
This is the same workflow used for restaurant promotions, event voucher systems, and offline coupon redemption.
If you're using Zapier to send coupons without a code management layer, three things tend to go wrong.
First, duplicate sends. A Zap fires twice for the same event, or a retry sends the same code to the same person. You burn through codes and confuse customers.
Second, reused codes. If you paste a single static code like "WELCOME10" into your Zap, everyone gets the same one. It gets shared in group chats, posted on coupon sites, and used by people outside your campaign.
Third, no validation at redemption. You sent the code, but was it actually redeemed? By the right person? Only once? Without a redemption layer, you have no way to know.
These problems compound at scale. More on this in our post on preventing coupon abuse in in-store promotions.
Coupon Carrier sits between Zapier and the customer. It handles the parts a basic Zap can't.
Each voucher has a "Mark as Used" button. The customer or staff taps it, and the voucher locks. Screenshots and forwards become worthless because the code is already spent.
Instead of a plain code, each person gets a Redeem Link. It opens a personal voucher page with a QR code. Staff scan it at the counter with their phone. The page handles redemption and prevents reuse, all without touching your POS.
Every delivery and every redemption is logged with a timestamp. You can see who got what code, when they used it, and whether it was valid.
Two of the most popular setups:
You now have everything you need to connect Coupon Carrier to any app in the Zapier ecosystem.
