How to add custom attributes to order at checkout

[AW1234]

Hi, I have a checkout app in wich I would like to add a "custom attribute" to the order

something like this (made with liquid)

in my app now I have this

useEffect(() => {
    // fetching data
        await applyAttributeChange({ key: 'dal_min', value: json.dals[0].dalMin.slice(0, 10) });
        await applyAttributeChange({ key: 'dal_max', value: json.dals[0].dalMax.slice(0, 10) });
      } catch (err) {
        console.error(err)
      }
    }
    fetchDal();
  }, []);

I test in my dev store and when I make an order I don't have the data in my order when I look in my back office

Did I make a mistake? is this a bug or is there no way to do that anymore?

Sounds like you're updating attributes on the cart not the order.

The Cart API is not the same as the Order API.

From what I understand, the `cart_token` is the only way to associate the cart with an order, and that's now deprecated. I would love if someone could point in the right direction of how to pass attributes from the cart to the order.

From what I can tell, there's no way to link a cart token to an order without relying on the Admin REST Order API which is deprecating the `cart_token` field.

Hey @AW1234 

What do you see if you log the result?

const result = await applyAttributeChange({
  key: '...',
  type: 'updateAttribute',
  value: '...',
});
console.log(
  'applyAttributeChange result',
  result,
);
