Pass Cart attributes through storefront api customAttributes?

Hi,

We use a headless setup creating our cart through the checkoutCreate mutation.

We are using an invoice app that requires extra bits of information be sent via the cart attributes. Their example (https://community.shopify.com/post/613718)

Would sending those 2 key/value pairs in customAttributes be the same?

Yes, those are the same.
