Every connection to the stream authenticates with an API key issued in the metar.ws portal. There are two equivalent ways to present it.

​
Presenting the key

Append the key as a query parameter on the WebSocket URL. This is the only option available to the browser WebSocket API.

​
Managing keys

Keys are created, listed, renamed and revoked from the Keys page in the portal. Revoking a key is enforced by the stream layer immediately: any open connection using a revoked key is closed within a second.
Your API key is your only credential. Do not commit it to a repository or ship it inside client-side code you distribute publicly. If you suspect a key has leaked, revoke it and create a new one.
