Can you automate unique discount code creation after purchase?

Technical Q&A

Topic summary

A user asks whether Shopify Flow can automatically generate unique discount codes after a customer purchases a specific product. The desired format would include the buyer’s name plus random characters (e.g., “123-MIKE-456”).

Key Findings:

  • Shopify Flow limitation: Native Flow cannot create discount codes directly.
  • Third-party solutions offered:
    • Mesa app: Can create unique discount codes per order using automation templates. A specific template link is provided for generating codes tied to new customer orders.
    • Regios Automatic Discounts app: Suggests using customer tags (e.g., “BoughtProductX”) combined with Flow to trigger automatic discounts. However, this approach does not generate unique codes—it applies a blanket discount to tagged customers.

Trade-offs:

  • Unique codes provide one-time use control but may clutter the backend.
  • Tag-based automatic discounts are simpler but lack uniqueness and usage limits (customers receive the discount on all future purchases unless the tag is removed).
  • One participant suggests removing tags after first use to prevent repeated discounting.

Status: The conversation remains open, with the original poster seeking true code uniqueness, which the automatic discount solution does not fully address.

Hi Kjankko,

Instead of creating a unique discount code per client (which can potentially clutter your backend if you have many), you can use automatic discounts.

For example, here’s how you can give Mike a 10% discount by combining Shopify Flow with my app, Regios Automatic Discounts:

First, create a workflow in Shopify Flow that adds a specific tag (ex. “BoughtProductX”) to a customer, if the order line items contain a specific product. Here’s a screenshot of a demo workflow:

Then, in Regios Automatic Discounts, use the “Customers with specific tags” option to give a 10% discount to all customers who have the “BoughtProductX” tag. Here’s a screenshot of what it looks like to create a discount based on a tag:

Once you’ve turned on your workflow and saved your discount, any customer who buys Product X, will automatically receive a discount on the products you specify.

If you don’t want to use an app, you can create your own discount using Shopify Functions.
