In ServiceNow Flow Designer, anApplication-based triggeris used to initiate a flow based on events from a specific application. Before using an application-based trigger, you must ensure that the necessaryapplication spokeand any requiredplug-insare activated.

Application Spokes:

Spokes are pre-built integration modules that allow Flow Designer to interact with different applications within ServiceNow.

Each application that provides triggers typically has its own spoke.

Plug-ins:

Some application spokes rely on additional plug-ins for full functionality.

These plug-ins must be enabled before the application-based triggers can be used.

A. Activate application trigger spoke→ Incorrect

There is no generic "Application Trigger Spoke." Instead, each application has its own spoke that must be enabled.

B. Activate trigger security rules→ Incorrect

Security rules govern access to triggers, but they do not enable the functionality of application-based triggers.

D. Assign Application trigger role [sn_app_trigger_write] to SME→ Incorrect

Roles likesn_app_trigger_writemay provide permissions but do not activate the trigger itself.

E. Activate application plugins only→ Incorrect

While plug-ins may be necessary, you also need to activate the corresponding spoke.
