[keycloak-user] Unable to access admin API (Get Identity Provider Instance)

Hi All, I was trying to call this API *GET /admin/realms/{realm}/identity-provider/instances/{alias} *and all I see in the error message is "Bearer". Can someone point me to what credentials I need to use to get the token in order to be able to access this API? Also any tests written for this API would also help. Am i missing something very obvious? Thanks, Robin
