How to non active Link Unfurling?

[Gesa]

Hi everyone, i want to non-activate Link Unfurling, can someone tell me how?

[Paul Curwen]

Link unfurling is automatically enabled by default as of Rome. To turn it off, admins can change the com.glide.cs.enable_link_unfurling system property to false.

Note for teams see: https://docs.servicenow.com/bundle/sandiego-employee-service-management/page/product/sn-teams/task/c...

For Virtual Agent see: https://docs.servicenow.com/bundle/rome-now-intelligence/page/administer/virtual-agent/concept/va-li...

Only certain url links will work OOTB to change this: 

Control unfurling with the Hostname allow list table

Use the Hostname allow list [sys_cs_hostname_allow_list] table to identify the list of hosts and domains that can be unfurled.

Note: For security reasons, only the hosts and domains in the Hostname allow list table can be unfurled.

The Hostname allow list table automatically includes these hosts and domains:

• Instance URL/hostname: <instance>.service-now.com or <customURL>.com
• Instance root domain: *service-now.com or *.<yourdomain>.com
• servicenow.com
• *.youtu.be*.youtube.com

As an admin, you can add hosts or domains to the Hostname allow list table:

1. 1. In the filter navigator, enter sys_cs_hostname_allow.list and select New.
