I want to get population counts for places in California. [Ideally Census Tracts, but that's not a supported geography in the population dataset?]

After reading through the documentation and requesting an API Key I built this URL:


I get the expected response in JSON format when I type it into a web browser but when I go connect the dataset in Carto, I get an error about supported files. Is the URL formatted properly? Am I connecting it incorrectly? I've been using the "connect dataset" and pasting the URL there.

As explained in the docs, CARTO does not support JSON files. The URL should point to a supported format such as csv, shp or geojson.
