The auth token will be required for future API requests. I did the following using the Insomnia REST client:
As a curl command that would be:
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{"username":"me@mymail.com", "password":"whatever"}' 'http://127.0.0.1:8080/api/auth/login'
