I've made a "starter" REST API Macro that works as an In/Out tool.
At the moment it it designed either for "Basic" authentication or for Bearer Token.
It handles parsing the JSON return data, stripping out the MetaData from the data and creating a proper table of data, as well as a MetaData output. (2 outputs, D and M).
Put this in your Macros folder and a new icon should show up in the In/Out section of the menu bar.
Ideas, Changes, Improvements are VERY wlecome.
