"GET", headers, payload
Explanation:
This Python script uses the Cisco DNA Center API to retrieve a list of network devices. The steps are:
* Import the required libraries: requests for making HTTP requests and json for handling JSON data.
* Define the API endpoint URL for retrieving network devices from Cisco DNA Center.
* Set up the request headers, including the content type and the authentication token (X-Auth-Token).
* Send a GET request to the API endpoint.
* Check the response status code to ensure the request was successful.
* If successful, parse and print the JSON response containing the list of network devices. Otherwise, print an error message.
