IApiComposeCallback extends ISubscribeApiCallback; an implementation must provide every signature below. Quote, account, and subscription callbacks receive the model declared in their signature; connection and heartbeat callbacks receive primitive parameters or no parameters.

Quote/option/future basic and BBO updates use separate callbacks. With UseFullTick=true, ticks go to FullTickChange(TickData); otherwise they go to TradeTickChange(TradeTick). Avoid blocking the callback thread.
Each callback receives the concrete data object shown in its signature; there is no common outer object. A subscribe or cancel command's uint return value correlates with the id in SubscribeEnd or CancelSubscribeEnd. Their result value is JSON; read its code field and require code == 0 for business success. GetSubscribedSymbolEnd receives only SubscribedSymbol and has no request ID, so the value returned by GetSubscribedSymbols() cannot be correlated with that callback.
Callback Payload Fields
The tables below list the available callback-object fields. For a field marked “Optional,” first check the corresponding Has... property; other value-type fields use their CLR default when absent.
Connection and Heartbeat Callbacks
Callback
Parameter
Type
Description
ConnectionClosed()
None
-
The connection closed; no payload
ConnectionKickout(int errorCode, string errorMsg)
errorCode / errorMsg
int / string
Error code and message when a new connection for the same Tiger ID replaces this connection
ConnectionAck()
None
-
Connection acknowledgement received; no payload
ConnectionAck(int serverSendInterval, int serverReceiveInterval)
serverSendInterval / serverReceiveInterval
int / int
Send and receive intervals the SDK uses to configure connection heartbeats, both in milliseconds
HearBeat(string heartBeatContent)
heartBeatContent
string
Server heartbeat content
ServerHeartBeatTimeOut(string channelId)
channelId
string
Identifier of the connection whose heartbeat timed out
