Creating new employee in Taleo to send to Fusion HCM gives a 401 error

Summary

Creating new employee in Taleo to send to Fusion HCM gives a 401 error. The exact error message is 'Error during Employee Creation status code:401. Not authorized. Operation: create'

Content

We have an integration between Taleo Business Edition and Oracle Fusion HCM, using the REST API.

When creating an employee in Taleo, it doesn't get transferred to Fusion HCM. The error we receive is the following:

"Error during Employee Creation status code:401. Not authorized. Operation: create"

Can anyone help with the resolution.

 

Thank you
