The Cortex® Xpanse™ ServiceNow ITSM App requires an
Cortex Xpanse Expander API token for installation.
The Cortex Xpanse Expander API is only available via HTTPS. The
API provides authentication via long-lived bearer tokens and short-lived
Cortex Xpanse provides the Bearer, such as Refresh, token as
part of the onboarding process for API access. Cortex Xpanse rotates
the Bearer token periodically while maintaining an overlap period
for the current Bearer token. Cortex Xpanse informs you before Bearer
token rotation. Also, you can request rotation of the Bearer token
for internal governance reasons.
