Reject discount codes

​

Rule overview

This rule allows you to reject certain discount codes at checkout based on the defined conditions. You can block specific discount codes from being applied using criteria such as order total amount, customer tags, shipping address, product tags, etc. When a customer enters a discount code that matches the configured conditions, the rule prevents the code from being applied and shows a custom rejection message at checkout. This helps enforce discount policies, protect margins, and prevent discount codes from being used in situations where they should not apply.

​

Sample configuration

The following steps show how to create and configure a Reject discount codes rule using the app.

​

Create a new rule

From your Shopify admin, open the app. In the sidebar, go to the Rules section and click “Create Rule”. Then, You’ll be redirected to the Select checkout rule type screen. Choose category “Discount” → select checkout rule type “Reject discount codes” → click “Select Rule”. Next, you’ll land on the Create new order discount rule screen, where you can configure your rule.

​

Rule configuration

To configure the rule, first optionally we can add a name such as “Reject discount codes” to describe what it does. Then, select the rule status: Testing, Active, Deactivated, or Scheduled. Here, as an example, we are going to choose Testing status, so we can quickly test the rule without affecting the checkout for actual customers. As part of the status settings, the optional Schedule section lets you control when an active rule starts and stops. Select a Start date and Start time for when the rule should begin. Optionally, check Set end date to choose an end date and time when the rule should automatically deactivate.

If you select schedule dates while the rule is set to Active, the status becomes Scheduled instead of Active. The rule will run from the start date and time until the end date and time, if one is set.

Next, on the same screen, configure the Combinations settings to control how this order discount interacts with other discounts. You can choose to allow it to combine with:

• Product discounts – This lets the order discount be used alongside any product level discounts. Make sure product discounts are also configured to combine with order discounts.
• Order discounts – This enables multiple order level discounts to be applied together. Ensure the other order discounts are also set to combine with order discounts.
• Shipping discounts – This allows the order discount to be used together with shipping level discounts. Confirm that shipping discounts are also set to combine with order discounts.

Next, on the same screen, select the relevant condition set, condition, and action.

As an example, here we are going to choose the default condition set 1. Then we are setting the rule to run when Order subtotal amount is greater than or equal to 300, and configuring it to reject the discount code “SAVE10”. The rejection message “This discount code cannot be used on this order” will be shown to customers at checkout when they try to apply it.

Also, you can optionally add translations for the rejection message in multiple languages by clicking Add translation and then selecting the languages you want to translate the message into. The main rejection message becomes the default message and is shown at checkout when no translation matches the customer’s language. Finally, click the Save button at the top to create and save your rule.

​

Test the rule

Since, the rule is set to testing status, we have to use [email protected] as the email, instead of the actual email, to run the rule at checkout. After setting the email, the checkout rule runs when the Order subtotal amount is greater than or equal to 300 and rejects the discount code “SAVE10” when the customer tries to apply it. We can verify that the rejection message “This discount code cannot be used on this order” is visible at checkout, as shown below.

​

Activate the rule

Once testing is done, we can activate the rule, so it can start making changes to the checkout for actual customers. Only activated rules can make changes to the checkout for all customers. Click on Rules in the sidebar to view all rules. Select the rule you want to activate, then click the Activate button to activate it.

​

Limitations

• This rule is incompatible with draft-order-based checkout and apps that use draft-order checkout.
• If your checkout URL includes .../checkouts/do/..., do stands for draft order. This rule won’t run on that checkout.
