🏷️ Expose your Discord presence and activities to a RESTful API and WebSocket in less than 10 seconds

Lanyard is a service that makes it super easy to export your live Discord presence to an API endpoint (api.lanyard.rest/v1/users/:your_id) and to a WebSocket (see below) for you to use wherever you want - for example, I use this to display what I'm listening to on Spotify on my personal website.

You can use Lanyard's API without deploying anything yourself - but if you want to self host it, you have the option to, though it'll require a tiny bit of configuration.

Get started in < 10 seconds

Just join this Discord server and your presence will start showing up when you GET api.lanyard.rest/v1/users/:your_id. It's that easy.

Socket Docs

The websocket is available at wss://api.lanyard.rest/socket. If you would like to use compression, please specify ?compression=zlib_json at the end of the URL.

Once connected, you will receive Opcode 1: Hello which will contain heartbeat_interval in the data field. You should set a repeating interval for the time specified in heartbeat_interval which should send Opcode 3: Heartbeat on the interval.

You should send Opcode 2: Initialize immediately after receiving Opcode 1.

Example of Opcode 2: Initialize:

{
  op: 2,
  d: {
    // subscribe_to_ids should be an array of user IDs you want to subscribe to presences from
    // if Lanyard doesn't monitor an ID specified, it won't be included in INIT_STATE
    subscribe_to_ids: ["94490510688792576"]
  }
}

Subscribing to multiple user presences

To subscribe to multiple presences, send subscribe_to_ids in the data object with a string[] list of user IDs to subscribe to. Then, INIT_STATE's data object will contain a user_id->presence map. You can find examples below.

Subscribing to a single user presence

If you just want to subscribe to one user, you can send subscribe_to_id instead with a string of a single user ID to subscribe to. Then, the INIT_STATE's data will just contain the presence object for the user you've subscribed to instead of a user_id->presence map.

Subscribing to every user presence

If you want to subscribe to every presence being monitored by Lanyard, you can specify subscribe_to_all with (bool) true in the data object, and you will then receive a user_id->presence map with every user presence in INIT_STATE, and their respective PRESENCE_UPDATES when they happen.

Once Op 2 is sent, you should immediately receive an INIT_STATE event payload if connected successfully. If not, you will be disconnected with an error (see below).

List of Opcodes

Opcode	Name	Description	Client Send/Recv
0	Event	This is the default opcode when receiving core events from Lanyard, like `INIT_STATE`	Receive
1	Hello	Lanyard sends this when clients initially connect, and it includes the heartbeat interval	Receive Only
2	Initialize	This is what the client sends when receiving Opcode 1 from Lanyard - it should contain an array of user IDs to subscribe to	Send only
3	Heartbeat	Clients should send Opcode 3 every 30 seconds (or whatever the Hello Opcode says to heartbeat at)	Send only

Events

Events are received on Opcode 0: Event - the event type will be part of the root message object under the t key.

Example Event Message Objects

`INIT_STATE`

{
  op: 0,
  seq: 1,
  t: "INIT_STATE",
  d: {
    "94490510688792576": {
      // Full Lanyard presence (see API docs above for example)
    }
  }
}

`PRESENCE_UPDATE`

{
  op: 0,
  seq: 2,
  t: "PRESENCE_UPDATE",
  d: {
    // Full Lanyard presence and an extra "user_id" field
  }
}

Error Codes

Lanyard can disconnect clients for multiple reasons, usually to do with messages being badly formatted. Please refer to your WebSocket client to see how you should handle errors - they do not get received as regular messages.

Types of Errors

Name	Code	Data
Invalid/Unknown Opcode	4004	`unknown_opcode`
