Show Suggested Answer

Suggested Answer: B

Access to Instana's REST API is secured using authorization tokens---an industry-standard best practice for API authentication and traceability. IBM documentation says: 'A personal or team API token is required to authenticate REST API calls.'

Tokens serve as credentials embedded in HTTP headers on each request, providing both identity and access control for the API consumer. Tokens are mandatory; without a valid token, any API requests are denied with a 401 Unauthorized error, regardless of whether a tool (such as CURL) is used. Tokens can be scoped for individual users (personal tokens) or teams (team tokens), enabling granular tracking and revocation as part of enterprise security policies. API tokens are generated from the Instana UI under the profile or team section. Cookies and raw client libraries (e.g., Python) are not authentication methods for Instana APIs.

I feel like cookies are less relevant here. Token is key!

True, but the token is still mandatory for security.

Ah, the age-old question of how to access those elusive Instana REST APIs. I'll take a wild guess and say... a magic wand?

I thought cookies were more for web sessions, so I don't think they are mandatory for Instana APIs, but I'm not completely sure.

I feel like CURL might just be one way to interact with the APIs, but I can't recall if it's strictly necessary.

I'm a bit stuck on this one. I know we need some kind of authentication, but I can't recall if it's a token, a cookie, or something else. I'll have to review my notes and try to remember the specifics of Instana's API authentication.

I'm pretty confident the answer is B) Token. From what I remember, Instana uses token-based authentication for their REST APIs, so you need to have a valid token to make requests.

I remember practicing a question about REST APIs, and I think it mentioned that a token is required for access.

Okay, let's see. The question is asking what's mandatory to use the Instana REST APIs, so it's probably related to authentication. I'm guessing it's either a token or a cookie, but I'm leaning more towards a token since that's a common way to authenticate APIs.
