Attendance API error: Provided authentication token is invalid.

Attendance API error: Provided authentication token is invalid.

Hi, I am trying to connect to the Attendance checkin and checkout API

This is the url that I am using: 
https://people.zoho.com/people/api/attendance?authtoken=*******************&dateFormat=dd/MM/yyyy HH:mm:ss&checkIn=16/01/2021 09:10:00&checkOut=16/01/2021 11:10:00&emailId=saurav*****@cross**lab**.com

But I am getting the following error: 
'{"response":{"message":"Error occurred","uri":"/api/attendance","errors":{"code":7202,"message":"Provided authentication token is invalid."},"status":1}}\n'

The auth token is newly generated by the Admin.

Regards,
Saurav Gupta
