Which authentication methods are supported in a REST message record?

• A. No authentication, Basic, OAuth 2.0
• B. OAuth 2.0 only
• C. No authentication only
• D. Basic and OAuth 2.0 only

Answer: (A)

REST message records in ServiceNow can be configured with different authentication methods to match what the target API expects. The supported options are No authentication (send the request without credentials), Basic authentication (send a username and password), and OAuth 2.0 (use an access token obtained through an OAuth flow). Since a REST message can use any of these methods depending on the API, the correct description includes all three. The other options restrict to only one method or omit a valid option, which is why they aren’t correct. For OAuth 2.0, you’d typically configure an OAuth profile to handle token retrieval and refresh; for Basic, you supply credentials; for No authentication, no credentials are sent.
