Introduction

This document describes the procedure for utilizing openAPI to manage Cisco Identity Services Engine (ISE) certificate.

Background

In the face of growing complexity in enterprise network security and management, Cisco ISE 3.1 introduces OpenAPI-formatted APIs that streamline certificate lifecycle management, offering a standardized and automated interface for efficient and secure certificate operations, helping administrators enforce strong security practices and maintain network compliance.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Cisco Identity Services Engine (ISE)

- REST API

- Python

Components Used

- ISE 3.3

- Python 3.10.0

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Configuration on ISE

Step 1: Add an Open API admin account

To add an API admin, navigate toAdministration > System > Admin Access > Administrators > Admin Users > Add.

API Admin

Step 2: Enable Open API on ISE

Open API is disabled by default on ISE. To enable it, navigate to Administration > System > Settings > API Settings >  API Service Settings. Toggle the Open API options. Click Save.

Enable OpenAPI

Step 3: Explore ISE open API

navigate to Administration > System > Settings > API Settings >  Overview. Click open API visit link.

Python Examples

Get All System Certificates Of A Particular Node

The API lists all the certificates of a particular ISE node.

Step 1: Required information for an API call.

Method

GET

URL

https://<ISE-PAN-IP>/api/v1/certs/system-certificate/<ISE-Node-Hostname>

Credentials

Use Open API account credentials

Headers

Accept :  application/json

Content-Type :  application/json

Step 2: Locate the URL that is utilized to retrieve certificates of a particular ISE node.

API URI

Step 3: Here is the example of Python Code. Copy and paste the content. Replace the ISE IP, username, password. Save as a python file to execute.

Ensure the good connectivity between ISE and the device running the python code example.

from requests.auth import HTTPBasicAuth

import requests

requests.packages.urllib3.disable_warnings()

if __name__ == "__main__":

url = "https://10.106.33.92/api/v1/certs/system-certificate/ISE-DLC-CFME02-PSN"

headers = {"Accept": "application/json", "Content-Type": "application/json"}

basicAuth = HTTPBasicAuth("ApiAdmin", "Admin123")

response = requests.get(url=url, auth=basicAuth, headers=headers, verify=False)

print("Return Code:")

print(response.status_code)

print("Expected Outputs:")

print(response.json())

Here is the example of expected outputs.
