+# Getiyo WebSocket Bridge
+
+Document that describes the messaging standard that Getiyo uses for WebSocket communication with external software and tools.
+
+## Connection
+
+Connect with a WebSocket client to the address of the Getiyo instance, use the port that is specified in your Getiyo config (default 4081).
+
+## Authentication
+
+Once you're connected to the WebSocket server it is very important you immediately send an `AUTH` message. If you are unable to authenticate within 5 seconds you'll be automatically disconnected. For authentication feedback see [errors](#message-type-error), if the authentication is succesful you'll receive the `SYSTEM` message `authOk`
+
+```JSON
+{
+    "packet": "AUTH",
+	"channelId": "fakeChannelId123",
+	"moduleIds": [
+        "fakeModuleId1",
+        "fadeModuleId2"
+    ],
+	"apiKey": "fakeApiKey"
+}
+```
+
+## Message Encoding/Decoding
+
+Messages are encoded as stringified JSON. Each message **always** includes a `packet` attributes. This attributes specifies the packet type, see the types below. This format applies to both directions of communication.
+
+## Message type `NORMAL`
+
+Normal messaging from module to external service.
+
+```typescript
+api.Libs.getWebSocket().broadcast('setScore', 'fakePlayerId123', 10);
+```
+
+```JSON
+{
+    "packet": "NORMAL",
+    "header": "setScore",
+    "args": [
+        "fakePlayerId123",
+        10
+    ]
+}
+```
+
+Messaging from external service to module.
+
+```JSON
+{
+    "packet": "NORMAL",
+    "moduleId": "fakeTargetModuleId",
+    "header": "setScore",
+    "args": [
+        "fakePlayerId123",
+        10
+    ]
+}
+```
+
+## Message type `ERROR`
+
+There are a messages that can only be send by Getiyo and contain server-side errors. The system message packet **always** contains a `type` attribute which specifies the system message type and a `message` attribute that has the actual error.
+
+```JSON
+{
+    "packet": "SYSTEM",
+    "type": "auth",
+    "message": "An error message."
+}
+```
+
+### `auth`
+
+Invalid authentication.
+
+### `notExist`
+
+Channel/Module/WebSocket Listeners
+
+## Message type `SYSTEM`
+
+There are a messages that can only be send by Getiyo and contain general data. The system message packet **always** contains a `type` attribute which specifies the system message type.
+
+### `id`
+
+The id of the socket client once authentication was completed.
+
+```JSON
+{
+    "packet": "SYSTEM",
+    "type": "id",
+    "id": "fakeSocketClientId123"
+}
+```
+
+### `authOk`
+
+Triggered when the authentication was completed.
+
+```JSON
+{
+    "packet": "SYSTEM",
+    "type": "authOk",
+}
+```
