Changing the Inbound websocket port


If you are changing the port offset, it is necessary to change the websocket port as well, regardless of whether or not you use websocket APIs.

From API Manager 2.1.0 onwards, you can create and publish websocket APIs. The default port used for websocket APIs is port 9099. 

If you are using port offsets with multiple API Manager nodes in a distributed mode, you need to change the in the <APIM_HOME>/repository/deployment/server/synapse-configs/default/inbound-endpoints/WebSocketInboundEndpoint.xml file by incrementing it with the same offset that you used in the <APIM_HOME>/repository/conf/carbon.xml file above.

For example, if your carbon.xml file has an offset value of 2, the WebSocketInboundEndpoint.xml file should have an value of 9101, as shown below.

Code Block
<inboundEndpoint xmlns=""
      <parameter name="">9101</parameter>
      <parameter name="ws.outflow.dispatch.sequence">outDispatchSeq</parameter>
      <parameter name="ws.pipeline.handler.class">org.wso2.carbon.apimgt.gateway.handlers.WebsocketHandler</parameter>
      <parameter name="ws.subprotocol.handler.class">org.wso2.carbon.inbound.endpoint.protocol.websocket.subprotocols.EchoSubprotocolHandler</parameter>
      <parameter name="dispatch.custom.sequence">true</parameter>
      <parameter name="ws.outflow.dispatch.fault.sequence">fault</parameter>
      <parameter name="ws.client.side.broadcast.level">0</parameter>
