Magento 2.x.x extension attributes API add object array
Have added custom attribute to order API with following info here: https://www.atwix.com/magento-2/adding-custom-attribute-to-api-response-in-magento-2/ It adds the “customer_feedback”: “this is my feedback” fine to api. How to add an Json object array ? E.G: “my_custom_object”: { “Key1”: “value!”, “Key2”: “value2” } Thanks
