Discount Code Passed As A Query Parameter To Checkout But It's Not Applying To Order

Hello @vaibhavrathod

  1. Verify that the discount code is still valid and has not expired. Also, check that the discount code is applicable to the specific products or collections the customer is attempting to purchase.

  2. Ensure that the discount code is set up to automatically apply at checkout. To do this, navigate to the discount code settings in your Shopify admin and confirm that the “automatic” option is selected.
