Hey @chahramane_hafid,
For Camunda 8 you need to use Service Task within your BPMN process. Camunda 8 implements the Service tasks with the help of job workers. We have a community build job worker for Python called Pyzeebe. You need to wrap the PyZeebe Worker around your script and then start your Python application. If you use Camunda 8 SaaS make sure to include your Cluster credentials so the worker can connect to your Cluster.
You are looking into Camunda 8 and not Camunda 7 right?
I hope that helps, Cheers
