I want to query the number of ArcGIS Online credits that a user has consumed in the past 24 hours. As things stand with the CreditManager, you can only query the entire organization. Could an additional parameter be added to the credit_usage method whereby you can specify a specific user or list of users?
It doesn't look like it's possible to query credit usage per user at this time using the ArcGIS API for Python. However, I definitely see how this could be useful. Please create a new post under ArcGIS Ideas requesting this functionality.
