Getting error while calling the Leave Booked and Balance Report API

Getting error while calling the Leave Booked and Balance Report API

Hi,

I get the following error 

{"error":{"code":7213,"message":"The provided OAuth token is invalid."},"uri":"/api/v2/leavetracker/reports/bookedAndBalance"}

The OAuth token is valid as I am using it in other APIs. Can you please let me know why this error occurred?
