SNOW-CAD Integrating and managing application data Practice Question
A company needs to integrate ServiceNow with an external HR system using REST API. The HR system requires OAuth 2.0 client credentials grant. Which ServiceNow application should be used to configure this integration?
⚠ Common exam trap
Candidates often confuse the tool for testing APIs (REST API Explorer) or the workflow automation layer (Flow Designer/IntegrationHub) with the actual configuration component (REST API Message) that handles OAuth 2.0 client credentials grant for outbound REST integrations.

Correct answer & explanation
✓
REST API Message
REST API Message is the dedicated ServiceNow application for defining and managing outbound REST integrations, including OAuth 2.0 client credentials grant. It allows you to configure the authentication profile, endpoint URL, HTTP method, and request/response handling in a structured, reusable way, making it the appropriate choice for integrating with an external HR system via REST API.
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 tool for testing API calls, not for configuring integration settings.
- ✗
Flow Designer
Why it's wrong here
Flow Designer creates workflows and actions, but the underlying REST message is defined in REST API Messages.
- ✓
REST API Message
Why this is correct
REST API Messages allow configuration of outbound REST calls, including OAuth authentication.
- ✗
IntegrationHub
Why it's wrong here
IntegrationHub is a premium feature for orchestrating multiple steps, overkill for a simple REST call.
