What base URLs are accessed with the access token?

• A. GraphQL endpoint
• B. REST and SOAP base URLs
• C. FTP base URL
• D. Streaming API endpoint

Answer: (B)

The key idea is that an OAuth access token is used to authenticate calls to the API endpoints. In Marketing Cloud, the token is what grants access when you request resources from the API, so you use it with the base URLs that expose the programmatic APIs.

REST and SOAP base URLs are the endpoints designed to be accessed with that token. For REST, you attach the access token in the Authorization header of each request, and you call the REST base URL. For SOAP, you include the token in the SOAP header to authenticate against the SOAP base URL. These are the primary token-protected interfaces, so they’re the base URLs accessed with the access token.

The other options refer to endpoints that aren’t the standard token-authenticated entry points in this context, or use different authentication patterns.
