Hi @imtiaz.n
Welcome to the Auth0 Community!
At this moment, searches on user metadata is case-sensitive, the Management API does not support wildcards for user metadata. Although not fitting of your use-case and just to leave this information here, the GET /api/v2/users endpoint is case insensitive as mentioned in our following Knowledge Article : Search for Users by Email with Auth0 Management API Endpoint
Other topics that fit your case and confirm that user metadata is not case insensitive :
- How to use wildcard and case-insensitive searches for user-meta data? - #2.
- Get all users by email consistency issues
My recommendation is to provide Feedback on this matter where other users can cast their vote. As this page is being monitored by our Product team, if a Feature Request gains popularity, it can accelerate the development and potential implementation in the future.
Hope this helped!
