CFSharePoint

Hello All,
My name is HP. I am working for Leidos and our team is supporting one of the FAA's CF applications.
I am assigned to find the way to make connection from our CF application to a sharepoint server.
I have never done it (using CFSharepoint) before.
The sharepoint administrator provides me with User Name, Password and the URL. Manualy I am able able to log in this URL with User Name, Password they provide me.
however the below is my code is to hit/connect their URL give me an error

<cfsharepoint action="getlistitems"
WSDL="https://xxx.xxx.xxx/ajg/apt-archive/Lists/JAT/AllItems.aspx"
username="xxxx"
domain="https://xxx.xxxx.xxx"
password="xxxx"
authtype="Basic"
name="listCollection"/>
<CFDUMP var="#listCollection#">

This is the error I got when I ran the above codes.

Unable to read WSDL from URL: https://xxx.xxx.xxx/ajg/apt-archive/Lists/JAT/AllItems.aspx.
Error: 401 Unauthorized. It is recommended that you use a web browser to retrieve and examine the requested WSDL document to ensure it is correct.

I wonder if you can help me on what should I fix in my codes or something that needs to be done from Sharepoint server side to allow me to connect ot it?

Thank you very much for your time
