Question

A network automation engineer is developing a Python script that will retrieve interface statistics from Cisco Catalyst Center via its REST API. During testing, the initial call to the /dna/system/api/v1/auth/token endpoint using HTTP Basic authentication succeeds, but subsequent calls to data endpoints return HTTP 401 Unauthorized. What is the MOST likely cause and correct resolution?

Accepted Answer

The script must include the token returned by the auth endpoint in the X-Auth-Token header of each subsequent API request.

Answer

The script should continue sending HTTP Basic credentials (username/password) in every request, since tokens are only used for the login call.

Answer

The script must disable TLS certificate verification so the API server will accept the requests.

Answer

The script should send the token as a URL query parameter because Catalyst Center does not read custom HTTP headers.
