[keycloak-dev] 405 on importing a realm

Hi, I am getting '405 Method Not Allowed' on trying to create a realm using keycloak's admin rest api. Following is the command that I am running curl -H "Content-Type: application/json" -H "Authorization: bearer $ACCESS_TOKEN" -d 'rep=$CONTENT_OF_THE_JSONFILE' -D- -X POST " http://mykeycloakurl.com/auth/admin/realms/master" Is this the right way?
