I see from the API guide you can make a call to retrieve more specified ROI figures
The guide doesnt explain (Maybe im glossing over it) the format of the expected values
Here is the example from the guide
What value is the ended before or ended after figure
The guide says the default for endedAfter is one week, so I tried 4 thinking this value may be the number of weeks but that gave me everything from the beginning of time.
How would I set this to a specific number of days i.e 30 days?
