WordPress REST API - ACF relationship - Add Categories and Featured Image (specific size) to Post Object

Hello . . We could use a hook to filter those data, in their documentation it is written that result of the api is filterable, means could be edited either adding or removing a data, I found out the following filters most likely would be used : acf/rest_api/{type}/get_fields acf/rest_api/{type}/prepare_item I could create an add-on or a snipet within a hour or two to display a featured image & categories in api response :) Thank you and regards, Eni
