I am new to ZOHO API and i want to integrate our organization's Biometric system with ZOHO using Zoho's Attendance API.

It would be gr8 if someone could answer the doubts mentioned below :

1) What is Authentication token....is it the same for a domain or it is dependent on the employee code.

2) If i generate an authentication token using the browser mode then what would be the validity of that token?

3) Can we use vbscript to post data to the ZOHO's attendance API ??

Thanks in advance.
