Hello I have a question regarding the metabase api.
Running a POST request on api/:card_id/query in the response tab I can see all data visualized plus info. More specificaly, there is a section in the json response tab called "Colls" and it show every info on the columns returned by the question this request runs.
How does this work? Where does the api get this information (what database tables, what columns etc)?
I am asking this because I have experienced a problem I try to understand with the metadata showing in the question.
