Auth0 Management API Returns Empty Result for Valid User ID
Apr 13, 2026
Overview
When querying the Auth0 Management API, the /api/v2/users endpoint returns an empty result for a valid user ID when filtering the search query with identities.user_id:<user_id>. This occurs because Auth0 misinterprets the data type when the user ID lacks quotation marks. Resolve this issue by enclosing the user ID value in double quotes to ensure Auth0 interprets it as text.
Applies To
- Auth0 Management API
- User Management Dashboard
Cause
When a user ID lacks quotation marks, Auth0 misinterprets the data type. This misinterpretation causes the API to return no results, even if the user ID exists.
Solution
How is the empty result issue resolved?
To resolve the empty result issue, enclose the user ID value in double quotes within the search query to ensure Auth0 interprets it as text.
- Format the query to include double quotes around the
<user_id>value.
q:identities.user_id="<user_id>"
