Which issue do you have? You should be able to display data from API Connector when the data the “use as” field is set to “data”
That seem to be the case in your screenshot.
In Data type, you need to select the Api Data type (probably something around Test query data’s hits)
And in Data source use get data from API and set also Test query data’s hits. This will be a list
The issue is that the repeating group data type is not listing this specific API call, it shows the other 2 i have which conveniently are GET calls. This one that i am testing is a POST call:
If call is initialized and set as data, you should probably send support ticket because this was not a problem before to use POST. I think someone yesterday also get issue with getting new call showings
