Postman api error WWW-Authenticate

Hi, I am trying to user Cyberark rest api from postman, I am able to do authentication test using https://pamdev.org.com/PasswordVault/API/Auth/CyberArk/Logon using basic usrename and pwd

but when I try to use get accounts using API -

https://pamdev.org.com/PasswordVault/api/Accounts?search=testusername&searchType=contains&sort=UserName&offset=25&limit=1000&filter=safeName eq mysafename

I am getting below error

401 an error has occured please contact your administrator

similar to 403 Forbidden, but specifically for use when authentication is possible but has failed or not yet been provided. The response must include a WWW-Authenticate header field containing a challenge applicable to the requested resource.

Could you please suggest me on this.
