HI all
in this Form its mentioned DMN only is not Available DMN API in Camunda 8

is it Available now, if Available how can I implement that

Thank you

No, as of the current version, Camunda 8 does not support DMN API. This feature is planned for future releases.

Out of interest what are you looking to do exactly? Deploy and Run a DMN table? anything else?

Hi @Niall

yes I ma trying to deploy and Run DMN table separately but as per my understanding I cannot do that so I need to integrate with BPMN

4

That the moment - indeed you’d need to create a BPMN model with a business rules task

In the zeebe engine, there is a grpc endpoint where you can call a decision directly…

Hi @Niall @Webcyberrob
then How to call DMN camunda 8 programmatically

7

Hi

You would need either a grpc client or a zeebe client…

If you want to quickly see it in action, postman has a grpc client you could use to help you get started…
