Hi @fleetcode,
Welcome to the Auth0 Community!
In the second request, where are you trying to send the request? It looks like you are currently sending it to https://tigertix.us.auth0.com/api/ when you would usually send it to a specific endpoint of the v2 API.
For example, to search users you would use: https://tigertix.us.auth0.com/api/v2/users
