How to trigger callActivity with a list of business keys?

Hi,
In parent camunda process I have list of child process camunda business keys and I want to trigger the callActivity delegate to trigger multiple child process with its own business key.

I made the callActivity parallel but the business key checkbox seems to accept one value and not a list.

You sholud pass the desired business key to each child prcess as part of the data; the child process should then call the API to change its business key.

I don’t know how to do what you want with just a call activity, even if it’s a multi instance one.

Hi @firstpostcommenter

Attached is a simple working example that includes a multi-instance call activity, where the business key is set to the name value of each element in the multi-instance collection.
