SalesIQ script connection issue.

SalesIQ script connection issue.

Hi. I have an issue with SalesIq script.
I write a chat bot. I want to use Visitor session feature.
I used this document https://www.zoho.com/deluge/help/salesiq-tasks.html

I created a connection 


Here is my SalesIq script example. 

It should work, but i get this error - 
{"error":{"code":1002,"message":"Invalid authorization header"}}
