Class: RTMClient
An RTMClient allows programs to communicate with the Platform's RTM API. This object uses the EventEmitter pattern to dispatch incoming events and has several methods for sending outgoing messages.

Constructors
new RTMClient()
new RTMClient(token, __namedParameters): RTMClient
Parameters
• token: string
• __namedParameters: RTMClientOptions = {}
Returns

Properties
activeTeamId?
optional activeTeamId: string;
The team ID for the workspace the client is connected to.
Defined in
activeUserId?
optional activeUserId: string;
The user ID for the connected client.
Defined in
authenticated
authenticated: boolean = false;
Whether or not the client has authenticated to the RTM API. This occurs when the connect method completes, and a WebSocket URL is available for the client's connection.
Defined in
connected
connected: boolean = false;
Whether or not the client is currently connected to the RTM API

Methods
addOutgoingEvent()
addOutgoingEvent(awaitReply, type, body)
addOutgoingEvent(
awaitReply,
type,
body?): Promise<RTMCallResult>
Generic method for sending an outgoing message of an arbitrary type. This method guards the higher-level methods from concern of which state the client is in, because it places all messages into a queue. The tasks on the queue will buffer until the client is in a state where they can be sent.
If the awaitReply parameter is set to true, then the returned Promise is resolved with the platform's acknowledgement response. Not all message types will result in an acknowledgement response, so use this carefully. This promise may be rejected with an error containing code=RTMNoReplyReceivedError if the client disconnects or reconnects before receiving the acknowledgement response.
If the awaitReply parameter is set to false, then the returned Promise is resolved as soon as the message is sent from the websocket.
Parameters
• awaitReply: true
whether to wait for an acknowledgement response from the platform before resolving the returned Promise.
• type: string
the message type
• body?: Record<string, unknown>
the message body
Returns
Promise<RTMCallResult>
Defined in
addOutgoingEvent(awaitReply, type, body)
addOutgoingEvent(
awaitReply,
type,
body?): Promise<undefined>
Parameters
• awaitReply: false
• type: string
• body?: Record<string, unknown>
Returns
Promise<undefined>
Defined in
disconnect()
disconnect(): Promise<void>
End an RTM session. After this method is called no messages will be sent or received unless you call start() again later.
Returns
Promise<void>
Defined in
send()
send(type, body): Promise<number>
Generic method for sending an outgoing message of an arbitrary type. The main difference between this method and
addOutgoingEvent() is that this method does not use a queue so it can only be used while the client is ready
to send messages (in the 'ready' substate of the 'connected' state). It returns a Promise for the message ID of the
sent message. This is an internal ID and generally shouldn't be used as an identifier for messages (for that,
there is ts on messages once the server acknowledges it).
Parameters
• type: string
the message type
• body = {}
the message body
Returns
Promise<number>
Defined in
sendMessage()
sendMessage(text, conversationId): Promise<RTMCallResult>
Send a simple message to a public channel, private channel, DM, or MPDM.
Parameters
• text: string
The message text.
• conversationId: string
A conversation ID for the destination of this message.
Returns
Promise<RTMCallResult>
Defined in
sendTyping()
sendTyping(conversationId): Promise<void>
Sends a typing indicator to indicate that the user with activeUserId is typing.
Parameters
• conversationId: string
The destination for where the typing indicator should be shown.
Returns
Promise<void>
Defined in
start()
start(options?): Promise<WebAPICallResult>
Begin an RTM session using the provided options. This method must be called before any messages can be sent or received.
Parameters
• options?: any
Returns
Promise<WebAPICallResult>
Defined in
subscribePresence()
subscribePresence(userIds): Promise<void>
Subscribes this client to presence changes for only the given userIds.
Parameters
• userIds: string[]
An array of user IDs whose presence you are interested in. This list will replace the list from any previous calls to this method.
Returns
Promise<void>
