Here is an example of a post request to create an account:
curl -H "Content-Type: application/json" \
-X POST \
-d '{"user":{"email":"[email protected]","password":"12345678","password_confirm":"12345678"}}' \
http://localhost:3000/users.json
And to authenticate:
curl -H "Content-Type: application/json" \
-X POST \
-d '{"user": {"email":"[email protected]","password":"12345678"}}' \
http://localhost:3000/users/sign_in.json
