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

In the below URL, the discount code is not applying again, the discount code is available in the parameter but does not apply automatically.

Any help would be great for us.

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.

We checked Everything and when we copy the discount code form URL parameter and paste in Shopify discount section in checkout then it’s working fine. But not applying automatic as passed in url.

Same issue here, it works on the /checkouts/c/… url but not /checkouts/sh/…
