The users endpoint returns it as a string for me. https://api.twitch.tv/kraken/users?login=dallas&api_version=5&client_id=mkz8q57of9hpecbduit36itpvles71q
For search, you’re correct. Hence the note of, “This is an ongoing change, so there might be some outliers.” Many, many teams own the set of endpoints inside of Kraken, and it takes time to get the updates to each service. That’s why we issued general guidance to treat them all as strings.
