WSO2 ESB kafka inbound endpoint acts as a message consumer. It creates a connection to ZooKeeper and requests messages for a topic.

To get started with the inbound endpoint, go to Configuring Kafka Inbound Endpoint. Once you have completed your configurations, you can consume the messages that are produced by the kafka producer via a topic.

To download the inbound JAR file, go to https://store.wso2.com/store/assets/esbconnector/details/b15e9612-5144-4c97-a3f0-179ea583be88 and click Download Inbound Endpoint. To use the inbound endpoint with ESB, copy the downloaded JAR file to the <ESB_HOME>/repository/components/dropins directory and restart your ESB server.

mvn clean install

You can create a third party connector and publish in WSO2 Store.
