Use **Discount Code Generator** when Roadmap should create a unique discount code after a customer event. This setup works well for post-review rewards, birthday offers, tier-promotion rewards, and post-purchase follow-up offers. ### Where to find it In Roadmap, open **Discounts / GWPs**, click **Create a new discount**, and choose **Discount Code Generator**. ### When to use it Use the generator when you need all three: * a unique code per reward event * Shopify discount rules managed in Roadmap * event-based delivery through Roadmap or Klaviyo Use [Klaviyo coupons](/discounts-and-gwp/using-gwp-and-discounts/when-to-use-roadmap-shopify-or-klaviyo-for-discounts.md) instead when Klaviyo should both generate and send the coupon. ### Delivery options Choose how the reward reaches the customer. #### Trigger a Klaviyo event Use this first. Klaviyo keeps reward emails inside your existing lifecycle program. You keep flow logic, design, testing, and reporting in one place. This is usually the best option when you already run retention email in Klaviyo. #### Send mail via Roadmap Use this for a simpler setup. This works when you want Roadmap to send the reward email directly and do not need a Klaviyo flow around it. {% hint style="info" %} If both options could work, start with **Trigger a Klaviyo event**. It gives you more control and scales better. {% endhint %} ### Available triggers The generator supports four trigger types. Use the links below to open the full setup guide for each trigger: * [Discount codes for reviews](/reviews/managing-reviews/review-rewards-and-limits/discount-codes-for-reviews.md) * [Discount codes for purchased products](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-on-member-promotion.md) * [Birthday discount codes](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-for-purchased-products.md) * [Discount codes on member promotion](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/birthday-discount-codes.md) #### When review is published Use this to reward a customer after a review is published. This trigger has its own review-specific settings such as **Reward frequency**. Read [Discount codes for reviews](/reviews/managing-reviews/review-rewards-and-limits/discount-codes-for-reviews.md). #### When specific products are purchased Use this to reward a customer after they buy selected products or collections. This works well for bounce-back offers and post-purchase cross-sell incentives. Read [Discount codes for purchased products](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-on-member-promotion.md). #### On member birthday Use this to send a birthday reward based on the member's stored birthday. Choose the timing based on the buying behavior you want to influence. Read [Birthday discount codes](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-for-purchased-products.md). #### On member promotion Use this to reward a member when they move into a new tier. This works well for tier celebration and immediate next-purchase activation. Read [Discount codes on member promotion](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/birthday-discount-codes.md). ### Shared configuration All generator setups use the same core sections: * **Name** and **Status** * **Trigger** * **Discount Code** * **Customer Eligibility** * **Mail Template** Most setups also need decisions on: * what the discount applies to * whether it supports one-time, subscription, or both * minimum spend, quantity limits, and expiry ### Related guides * [Discount codes for purchased products](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-on-member-promotion.md) * [Birthday discount codes](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/discount-codes-for-purchased-products.md) * [Discount codes on member promotion](/discounts-and-gwp/using-gwp-and-discounts/discount-code-generator/birthday-discount-codes.md) * [Discount codes for reviews](/reviews/managing-reviews/review-rewards-and-limits/discount-codes-for-reviews.md) * [When to use Roadmap, Shopify, or Klaviyo for discounts](/discounts-and-gwp/using-gwp-and-discounts/when-to-use-roadmap-shopify-or-klaviyo-for-discounts.md) * [How to integrate Roadmap with Klaviyo](/reviews/integrations/klaviyo-review-integration/how-to-integrate-roadmap-with-klaviyo.md) --- # Agent Instructions This documentation is published with GitBook.
