The guy below was right. Your hitting the wrong url. If that didn’t fix it, it’s probably your postman set up. Does curl work? Ex:

curl -i -H
“Content-Type: application/json”
-X POST
-d ‘{ “auth”: “you key”, “name”: “some name”, “title”: “some name” }’

I’m gonna be dating myself a bit here haha, but I released my first game in 2011. It’s even still available to play if you have flash player lol. https://www.newgrounds.com/portal/view/576782

He meant remove it from the post, anyone can use it to make requests to your server lol
