On task completion get new tasks

I’m fairly new to camunda and use the rest api to communicate with a c# appliaction. What I want to do is to get a list of all tasks that started because I completed another usertask (over rest api).
The process instance of the completed task might contain further (for me irrelevant) tasks, that are already running bevor my task was completed.

I guess this should be pretty basic but I can’t figure out how to get this information.

Hi Bottcherk,

What about using this API? You can pass in filtering parameters such as the processInstanceId and created after to filter and thus list additional user tasks created for your process instance created since a given point in time…
