# Deprecated fields in the Growth History endpoint

We’ve stopped calculating the (deprecated) `existing`, `options`, and `imports` fields for the [Growth History endpoint](/developer/marketing/api/lists/list-growth-history), and API responses will have a value of zero for these fields.

The data in these fields can be accessed in a more understandable way in other fields, and returning the data in these fields was slow and added infrastructure load when these endpoints were requested.
