A few LNbits extensions also make use of a weird and useful websocket/GET tool built into LNbits, such as extensions Copilot and LNURLDevices<br/>
|

You can subscribe to websocket with <code class="bg-grey-3 text-black">wss:{{location}}/api/v1/ws/{SOME-ID}</code><br/>
|

You can post to any clients subscribed to the endpoint with <code class="bg-grey-3 text-black">{{protocol + location}}/api/v1/ws/{SOME-ID}/{THE-DATA-YOU-WANT-TO-POST}</code><br/>
