With the 2018 update to the User Interface, the API Builder Developer Tool has also received some updates. Previously you were limited to pre-formatted selections from the drop down menu to build your request. Now you can enter your own parameters without having to use the drop down, including copying and pasting your XML or JSON right into the API Builder. There is also job a ‘last request history’ option. By clicking the clock icon in the right hand of the API Builder window, it will populate the builder with your most recent API request.
