The answer is the OAuth client ID and client secret from the third-party system, along with the token request endpoint URL. These two configurations are mandatory because the OAuth 2.0 client credentials grant flow is a machine-to-machine authentication method where the client directly exchanges its credentials—the client ID and secret—for an access token at a specific endpoint, without any user involvement or discovery steps. On the ServiceNow Certified Application Developer CAD exam, this question tests your understanding of IntegrationHub’s role in external REST integrations, often trapping candidates who mistakenly include user authorization endpoints or refresh token URLs. A common memory tip is to remember that client credentials are like a key and lock: you need both the ID and secret to unlock the token, and you must know exactly which door (the token endpoint) to knock on.
SNOW-CAD Platform Features and Integration Practice Question
This SNOW-CAD practice question tests your understanding of platform features and integration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A ServiceNow developer is building an integration using IntegrationHub to connect to a third-party system via REST. The system requires OAuth 2.0 with client credentials grant flow. Which TWO configurations are mandatory for setting up this integration in IntegrationHub?
Option B is correct because the client credentials grant flow requires a direct token request endpoint URL where the client sends its credentials (client ID and secret) to obtain an access token. IntegrationHub must be configured with this specific endpoint to complete the OAuth 2.0 handshake, as the grant type does not involve user interaction or discovery endpoints.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
OAuth server discovery URL (well-known endpoint)
Why it's wrong here
Discovery is optional; the token endpoint can be manually specified.
Read the scenario before looking for a memorised answer.
✗
Base64 encoding of the client secret
Why it's wrong here
Not required; ServiceNow encrypts secrets automatically.
✗
Username and password for user impersonation
Why it's wrong here
Client credentials do not involve user impersonation.
✓
OAuth client ID and client secret from the third-party system
Why this is correct
Mandatory for client credentials grant.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ServiceNow often tests the distinction between mandatory and optional OAuth 2.0 configurations, and the trap here is that candidates mistakenly think the well-known discovery URL or Base64 encoding is required, when in fact the client credentials flow only needs the token endpoint and the client credentials themselves.
Detailed technical explanation
How to think about this question
In the OAuth 2.0 client credentials grant (RFC 6749 Section 4.4), the client authenticates directly with the authorization server using its client ID and secret, typically via a POST request to the token endpoint with grant_type=client_credentials. IntegrationHub stores these credentials securely and constructs the request automatically, but the token endpoint URL must be explicitly provided. A subtle behavior is that some third-party systems may require the client secret to be sent as a form parameter rather than in the Authorization header, which IntegrationHub can accommodate via custom credential types.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What is the correct answer to this question?
The correct answer is: Token request endpoint URL (e.g., https://example.com/oauth/token) — Option B is correct because the client credentials grant flow requires a direct token request endpoint URL where the client sends its credentials (client ID and secret) to obtain an access token. IntegrationHub must be configured with this specific endpoint to complete the OAuth 2.0 handshake, as the grant type does not involve user interaction or discovery endpoints.
