How can I send message from one pool to another without the need to use a java class?
(typical via rest or similar)
If have found message / Deliver: but i guess that is to trigger a start event, I am looking for the delivery in a processtep.
Hey Tommy! If you do not want to write any Java Class or other implementation for such purpose you could rely on a so called “Connector”.
Right here you can find an example about it:
Right here is a very nice post about how to configure connectors using the Modeler as well:
Hopefully this was helpful for you!

Isn’t there a simpler solution, like using rest?
Of course there is a Rest connector as well. The mail connector was just an example.
I find that this github repo explains the usage of the http connector pretty well: https://github.com/rob2universe/camunda-http-connector-example
Great, Pity it’s not included in Camunda from start 
Apparently this feature is not very often used because it is often recognised as limiting. Usually people tend to write their own reusable HTTP client for such purposes.
For this solution you do only need to get the proper imports. This can also achieved in the Platform Run Distro and doesn’t require a java project.
This interests me: “For this solution you do only need to get the proper imports. This can also achieved in the Platform Run Distro and doesn’t require a java project”.
Do you have any example?
To start with you can get familiar with Camunda Platform Run right here:
https://docs.camunda.org/manual/latest/user-guide/camunda-bpm-run/
To add a plugin / dependency you need to put the required jar in the userlib folder.
Let me know wether you have other questions around this topic!
