Hi,
Over the last couple of days we’ve been encountering a problem with an existing production system which searches for Amplitude records by Amplitude ID using the User Search API.
e.g: amplitude.com/api/2/usersearch?user=foo
We’re consistently seeing no records returned by the API when we’ve verified that an Amplitude record exists with the exact Amplitude ID we’re searching for.
The same API is still able to return matches when searching using Device IDs.
Has this functionality of the User Search API been deprecated?
