V2 of the API, only seems that hour, minute, and day time frames work. The API documentation here clearly states that you can use 15 minute candle data.
! am using the query below, but when trying to use TimeFrame.15Min, I get an error. Is 15 minute data possible in V2?
api.get_bars(symbol, ‘TimeFrame.15Min’, ‘2021-01-15’, ‘2021-09-15’, adjustment=‘raw’).df
