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” }’
https://someurl.com/api/v3/community

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