# How to use coupon codes in OptiMonk campaigns Canonical URL: https://support.optimonk.com/en/articles/how-to-use-coupon-codes-in-optimonk-campaigns OptiMonk can show a discount code on your popup, so your visitors get their reward the moment they sign up. You can hand out one fixed code to everyone, or a different, unique code to every visitor. --- ## 1. Prepare your store First make sure the discount itself exists in your store — otherwise your store will not recognise the code your popup shows. Every platform does this differently; here are their own guides for the most common ones: - [Shopify](https://help.shopify.com/en/manual/promoting-marketing/discount-codes/create-discount-codes) - [WooCommerce](https://woocommerce.com/posts/coupons-with-woocommerce/) - [3dcart / Shift4Shop](https://www.shift4shop.com/lp/features/3dcarts-promotion-coupon-features/) - [BigCommerce](https://support.bigcommerce.com/s/article/Using-Coupon-Codes) - [CoreCommerce](https://support.corecommerce.com/support/solutions/articles/43000481581-tiered-discounting-on-select-items-coupon-) - [OpenCart](http://docs.opencart.com/en-gb/marketing/coupon/) - [Shopware](https://docs.shopware.com/en/shopware-5-en/marketing-and-shopping-worlds/vouchers) *💡 On a connected Shopify store you can skip this step — OptiMonk can check and even create the discount for you. See Coupon codes in OptiMonk — additional features for Shopify users.* --- ## 2. Ask for a coupon popup There is no template to pick. Say what you want in the chat — *"a welcome popup with 10% off for first-time visitors"* — and the concepts you get back already contain a coupon box, usually on the thank-you step shown after the signup. If you did not ask for one, you can add it later in the chat: *"add a coupon code element"*. --- ## 3. Set the code while you create the campaign After you pick a design, the plan walks you through a few short steps, and one of them is **Coupon** (*shown on step 2, after the signup*). - The code read from the design is already filled in — change it here and the thank-you step is drafted with your final code. - Pick the type: **Fixed code** (*Every visitor sees the same code.*), **Unique codes** (*One campaign-level pool (uploadable after create).*) or, on a connected Shopify store, **Shopify coupon** (*A single-use code is generated in Shopify.*) - If you are running an A/B test with more than one coupon design, you can choose **Same coupon** (the same type and code for every variant) or **Different per variant**. --- ## 4. Change the coupon on a built popup Once the popup exists, its coupon settings live in the editor: 1. Open the campaign, open the design, and click **Drag & drop editor**. 2. Click **Coupon** in the top bar. The **Coupon code** panel opens (*type, code pool, fallback*). *💡 The code cannot be typed over directly on the canvas. The editor says why: an emptied or mistyped code would go live unnoticed — so it is set here instead. You can also ask for it in the chat: "change the coupon to XY".* If your popup hands out more than one coupon, the panel lists them all under **Coupon codes (n elements)**, each with its own field. --- ## 5. Hand out unique codes Choose **Unique codes** (*Every visitor gets their own code from the uploaded pool.*) and each visitor is served a different code from a list you upload. 1. Under **Code pool**, paste your codes into the box — *separated by commas, spaces or line breaks* — or use **.txt / .csv upload** to load a file. 2. The panel counts them for you: *n codes in the list*. 3. Once saved, the pool shows its live state: **Available**, **Reserved** and **Handed out**. *💡 The list overwrites the whole available pool; codes currently reserved are kept. And remember: these codes have to exist in your store too.* ### What happens when the codes run out Under **When the codes run out** you decide: - **Don't show the campaign** — the popup stops appearing rather than showing an empty box. - **Show a text instead of the code** — with your own message, for example *The coupons ran out :(* If you pick Unique codes but upload nothing, the panel warns you: *No codes uploaded — the campaign won't show up at all.* --- ## 6. Save and publish 1. Press **Save** in the coupon panel. 2. Press **Save & Exit** in the editor. 3. If the campaign is not live yet, publish and activate it. If it is already live, saving pushes the new creative to it. --- ## Things the panel will tell you - *The coupon code can't be empty — with an empty code the visitor sees an empty coupon box and the copy button copies nothing.* - *No code on: . There the visitor sees an empty coupon box — enter the code and save.* — fill the code in on the other view too. - *There is no coupon-code element on the popup, so the settings can't be saved.* — ask in the chat to add one. --- ## Additional features for Shopify users Connected Shopify stores get more: OptiMonk can look up and create the discount for you, generate a unique single-use code per visitor with a prefix and an expiry, and apply the discount automatically at checkout.
