Hello,

We are looking to include the “Additional Details” field from the order screen (circled in red below) in our Notifications for New Orders, how can we do this? This is different from Order Notes that customers enter in their Cart when checking out.

Thank you!

Hello @jjf262 those are cart attributes, order attributes, see the notification section of the cart attributes customization forum guide:

https://community.shopify.com/c/shopify-design/cart-use-cart-attributes-to-collect-more-information/m-p/613718

Thanks for the help, we tried adding this code to our New Order notification to include the Additional details but it did not work:

{% for attribute in attributes %}
{{ attribute | first }}: {{ attribute | last }}

{% endfor %}

Any insight on how to fix this?
