# Waffle API docs (currently not implemented)
|
|
|
|
*Again, this IS NOT YET IMPLEMENTED IN THE CURRENT BRAINLET RELEASE*
|
|
|
|
# Gateway
|
|
|
|
Waffle uses a WebSocket gateway to transmit various updates from the server to the client and vice-versa (new message, user disconnecting, connect to voice, etc.)
|
|
|
|
# Gateway Payload format
|
|
|
|
All payloads sent through the gateway are *string payloads*. They all start with a number represeting the "instruction", followed by a "@" character (to delimit the instruction number from the rest of the payload), after which comes the data for the specific instruction.
|
|
|
|
Example packet:
|
|
```json
|
|
23@this is my payload data
|
|
```
|
|
Note for the example above: The "this is my payload data" text should not be user controlled. If user controlled input is required, it must be sanitized and/or passed as a JSON field.
|
|
|
|
Packets can also have JSON as a payload:
|
|
```json
|
|
32@{"name":"Alice"}
|
|
```
|
|
|
|
## Instructions
|
|
|
|
## 0:HELLO
|
|
*Part of handshake, Server to client*
|
|
|
|
Sent by the server to the client as soon as possible after they connect to the gateway.
|
|
|
|
This payload can contain a JSON object with various information about the server. It should be relied on only when absolutely necessary.
|
|
|
|
Example:
|
|
```json
|
|
0@{}
|
|
```
|
|
|
|
## 1:YOO
|
|
*Part of handshake, Client to server*
|
|
|
|
Sent by the client as soon as possible after receiving the HELLO instruction.
|
|
|
|
|
|
JSON data format:
|
|
| Field | Description |

|
|
| token | The authentication token |
|
|
|
|
Example:
|
|
```json
|
|
1@{"token":"my totally real token"}
|
|
```
|
|
|
|
If the token is invalid, or the connection is otherwise rejected, the client should be disconnected as soon as possible, and no YOO\_ACK should be sent.
|
|
|
|
## 2:YOO\_ACK
|
|
*Part of handshake, Server to client*
|
|
|
|
Sent by the server as soon as possible after processing the YOO payload from the client.
|
|
|
|
JSON data format:

## 5:ACTION\_UPDATE\_STATUS
