Get your Cortex XDR API Key.

1. In Cortex XDR , navigate to Settings → Configurations → Integrations → API Keys.

2. Select + New Key.

3. Choose the type of API Key you want to generate based on your desired security level: Advanced or Standard.

   The Advanced API key hashes the key using a nonce, a random string, and a timestamp to prevent replay attacks. cURL does not support this but is suitable with scripts. Use the Advanced Key Python 3 Example to create the advanced API authentication token.

4. If you want to define a time limit on the API key authentication, mark Enable Expiration Date and select the expiration date and time.

   Navigate to Settings → Configurations → Integrations → API Keys to track the Expiration Time field for each API key. In addition, Cortex XDR displays the API Key Expiration notification in the Notification Center one week and one day prior to the defined expiration date.

5. Provide a comment that describes the purpose of the API key, if desired.

6. Select the desired level of access for this key.

   You can select from the list of existing Roles, or you can select Custom to set the permissions on a more granular level. Roles are available according to what was defined in the hub as described in the Manage Roles section of the Cortex XDR Administrator’s Guide.

7. Generate the API Key.

8. Copy the API key, and then click Done. This value represents your unique Authorization:{key}.

   Caution

   You will not be able to view the API Key again after you complete this step so ensure that you copy it before closing the notification.

Get your Cortex XDR API Key ID.

1. In the API Keys table, locate the ID field.

2. Note your corresponding ID number. This value represents the x-xdr-auth-id:{key_id} token.

Get your FQDN.

1. Select your API key and click Copy URL .

You can use the CURL Example URL to run the APIs.

Make your first API call.

The following examples vary depending on the type of key you select.

You can test authentication with Advanced API keys using the provided Python 3 example. With Standard API keys, use either the cURL example or the Python 3 example. Don’t forget to replace the example variables with your unique API key, API key ID, and FQDN tenant ID.

After you verify authentication, you can begin making API calls.

Standard Key cURL Example

curl -X POST https://api-{fqdn}/public_api/v1/{name of api}/{name of call}/ 
-H "x-xdr-auth-id:{key_id}" 
-H "Authorization:{key}" 
-H "Content-Type:application/json" 
-d '{}'

Standard Key Python 3 Example

import requests
    def test_standard_authentication(api_key_id, api_key):
    headers = {
        "x-xdr-auth-id": str(api_key_id),
        "Authorization": api_key
    }
    parameters = {}
    res = requests.post(url="https://api-{fqdn}/public_api/v1/{name of api}/{name of call}",
						headers=headers,
						json=parameters)
    return res

Advanced Key Python 3 Example

import requests

from datetime import datetime, timezone
import secrets
import string
import hashlib
import requests

def test_advanced_authentication(api_key_id, api_key):
   # Generate a 64 bytes random string
    nonce = "".join([secrets.choice(string.ascii_letters + string.digits) for _ in range(64)])
    # Get the current timestamp as milliseconds.
    timestamp = int(datetime.now(timezone.utc).timestamp()) * 1000
    # Generate the auth key:
    auth_key = "%s%s%s" % (api_key, nonce, timestamp)
    # Convert to bytes object
    auth_key = auth_key.encode("utf-8")
    # Calculate sha256:
    api_key_hash = hashlib.sha256(auth_key).hexdigest()
    # Generate HTTP call headers
    headers = {
        "x-xdr-timestamp": str(timestamp),
        "x-xdr-nonce": nonce,
        "x-xdr-auth-id": str(api_key_id),
        "Authorization": api_key_hash
    }
    parameters = {}
    res = requests.post(url="https://api-{fqdn}/public_api/v1/{name of api}/{name of call}",
						headers=headers,
						json=parameters)
    return res
