Exam 200-901 Topic 4 Question 451 Discussion

The 401 Unauthorized status code indicates that the request lacks valid authentication credentials. When using OAuth2 for authenticating with the Cisco Webex API, the correct approach is to include a Bearer token in the Authorization header.
Option A:
header = {"Authorization": "Bearer YOUR_TOKEN"}
This option correctly formats the Authorization header, which is necessary for the Webex API to authenticate the request. The Bearer token is a type of token used by OAuth2 to access protected resources.
Authorization Header: The header must contain the key "Authorization" with the value formatted as "Bearer YOUR_TOKEN".
Bearer Token: The Bearer keyword followed by a space and the token itself is the correct way to pass the OAuth2 token in the header.
Other Options:
Option B:
Incorrect because it uses "Authentication" instead of "Authorization".
Option C:
Incorrect because it combines Authentication and Bearer incorrectly without a space.
Option D:
Incorrect for the same reason as Option C.
