Resource Owner Password Grant

I have implementef Resource Owner Password Grant and set grant type as “http://auth0.com/oauth/grant-type/password-realm” now I am able to get token from “/oauth/token”

but when I am calling my api which is secured I am getting 401.

Is there any setting need to be done at my end

Hello,

We need much more information to be able to help with this.
The logs on your API may be able to tell you why the 401 was returned.

I also strongly recommend using a redirect flow, not ROPG.
