I'm using the Zoho Projects v3 API to create a task. The task is created successfully, but in order to assign the task owner, the "Create a Task" API also requires the zpuid of the task owner. Unfortunately I cannot find any user-related API calls that return the user's zpuid. I can only find the user's id and zuid. Could you please let me know how I can find a Zoho Projects user's zpuid? Thank you in advance.
