Hi,

How do we publish message and complete the receive task in Camunda Cloud.

Can you please post sample code to implement in Java/Rest API.

Thanks,
Geetha

Hi @Geetha_k

Welcome to the forum.

Camunda 8 (nee Cloud) uses gRPC as it’s primary over-network protocol (rather than REST) You can read here in the docs about how you might want to send a message and complete a task.

If you’re using the Zeebe Client though you can use something like this:

  final PublishMessageResponse response = client.newPublishMessageCommand()
                .messageName(messageRequest.messageName)
                .correlationKey(messageRequest.correlationKey)
                .timeToLive(Duration.ofSeconds(Long.parseLong(messageRequest.ttl)))
                .variables("{\"TimeSent\":\""+ timestamp.toString()  +"\"}")
                .send()
                .join();

Hi Niall,

Thanks for the response. I tried the same Zeebe client sample code you shared here, but still the task is waiting for the response and the operate I could see an incident with below message "failed to evaluate expression ‘msg’: no variable found for name ‘msg’.

Could you please help me here.

Thanks,
Geetha
