We have created a product with a custom option (free text field). The customer enters data, now this data should be exported via enter image description here curl -X GET --header "Accept: application/xml" --header "Authorization: Bearer $B" "https://shop.example.com/rest/english/V1/orders/105"

But I cannot find the data of the custom option in the REST result.

Is that normal?

Is it a bug?

  • You need to call custom Order API and make code in Customer Interface. Commented Sep 24, 2018 at 8:25
  • Do you mean Customer Interface or Custom Interface? I wish this would be in the standard API ... Created an issue over at GitHub - somehow it feels like a bug but it might be more a obvious missing feature github.com/magento/magento2/issues/18227

I solve it by creating an Extensionattribute and copy logic over from the core giftmessage attribute which also adds extension attributes to orderItems.
