Fusion - Create an issue (OPTASK) within an existing task

[LaurensKr1]

Hi,

I am able to create a new issue within a project using an API call. 

What field should I use to update / set when I want to be sure the new issue is actually within an existing task within the project using a custom API call.

When creating set source object to attach the issue to a task.
