SNOW-CAD Integrating and managing application data Practice Question
A company is integrating ServiceNow with an external ticketing system using a custom REST API. The integration should push updates from ServiceNow to the external system when a change request is approved. Which ServiceNow feature is best suited for this?
⚠ Common exam trap
Watch out — candidates often confuse REST API Explorer (a manual testing tool) with the ability to automate outbound calls, or think that a Scheduled Job is appropriate for event-driven integrations, missing the need for real-time, state-change-triggered execution.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Business Rule with outbound REST call
A Business Rule with an outbound REST call is the best fit because it triggers automatically on the 'approved' state change of a change request and can execute a synchronous or asynchronous REST API call to the external ticketing system. This allows real-time push of updates without manual intervention or polling, directly meeting the requirement to push updates upon approval.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
REST API Explorer
Why it's wrong here
REST API Explorer is a manual testing tool, not for automated integration.
- ✓
Business Rule with outbound REST call
Why this is correct
Business Rules can trigger on record updates and make outbound REST calls using the RESTMessageV2 API.
- ✗
Access Control List (ACL)
Why it's wrong here
ACLs control data access, not outbound integration.
- ✗
Scheduled Job
Why it's wrong here
Scheduled Jobs run on a timer, not immediately upon approval.
