Subscription (Web socket)

Overview

Our GraphQL subscription endpoint:
wss://api-ws.dlive.tv
Note that, the subscription does not work like normal GraphQL subscription in the sense that it returns every possible event with all available fields regardless of the subscription query given. So you cannot only listen to, say chat messages, and so you need to filter out uninterested events.
The server sends a "ka" message every 25 seconds. If you do not receive "ka", you should reconnect.

How to connect

Clients establish a secure WebSocket connection to our endpoint.
Client sends
{
"type": "connection_init",
"payload": {
"authorization" : "YOUR_APP_ACCESS_TOKEN"
}
}
and expects to receive an ack:
{
"type":"connection_ack"
}
Then client could subscribe to a particular endpoint by sending as follows:
{
"id":"1",
"type":"start",
"payload":{
"query":"subscription{streamMessageReceived(streamer:\"dbl-lee\"){__typename}}"
}
}
The id is a unique string during current connection and "dbl-lee" is the username of the streamer (NOT displayname).
When a chat message is received, you should receive:
{
"payload":{
"data":{
"streamMessageReceived":[
{
"__typename":"ChatText",
"type":"Message",
"id":"80364c42-1d4e-49f2-ac16-dffc9cb2e3d8",
"content":"hello",
"createdAt":"1560812097380375004",
"sender":{
"__typename":"StreamchatUser",
"id":"streamchatuser:testpotato",
"username":"testpotato",
"displayname":"testPotato",
"avatar":"https://images.prd.dlivecdn.com/avatar/default22.png",
"partnerStatus":"NONE",
"badges":[]
},
"role":"None",
"roomRole":"Member",
"subscribing":false
}
]
}
},
"id":"1",
"type":"data"
}
You could subscribe to multiple streamers and distinguish server payload by the id string. The schema of different events could be found by clicking corresponding types here.
Note that, sending message is not through web socket but by mutation.
To unsubscribe to a particular endpoint, just send stop message with id as follows:
{
"id":"1",
"type":"stop"
}
