# Authentication

To access the Plugin API, all requests need to be authenticated via a Game Server secret key which is found in the [game servers section](https://creator.tebex.io/game-servers) of your creator panel.

Supply the secret key by setting the `X-Tebex-Secret` header in all requests to the API.

Please note that all requests to the API must be sent via HTTPS.
