Get Started with Cortex XDR APIs

What you need to run Cortex XDR APIs.
Before you can begin using Cortex XDR APIs, you must generate the following items from the Cortex XDR app:
The API Key is your unique identifier used as the
header required for authenticating API calls.
Depending on your desired security level, you can generate two types of API keys,
, from your Cortex XDR app.
The API Key ID is your unique token used to authenticate the API Key. The header used when running an API call is
The Advanced API Key hashes the key using a nonce (a random 64 character string) and a timestamp to prevent replay attacks and is suitable for proprietary scripts. However, due to the reverse hashing script requirement you cannot use this API key type with cURL. To enable cURL, you must first reverse the hash. See the provided script for an example of how to do this.
To integrate with Cortex XSOAR you must generate an Advanced Key.
The FQDN is a unique host and domain name associated with each tenant. When you generate the API Key and Key ID, you are assigned an individual FQDN.
Cortex XDR API URIs are made up of your unique FQDN, the API name, and name of call. For example,
https://api-{fqdn}/public_api/v1/{name of api}/{name of call}/
The following steps describe how to generate the necessary key values.
  1. Get your Cortex XDR API Key.
    1. In Cortex XDR, navigate to
      API Keys
    2. Select
      + New Key
    3. Choose the type of API Key you want to generate based on your desired security level:
    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
      API Keys
      to track the
      Expiration Time
      field for each API key. In addition, Cortex XDR displays a 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 for the API key, if desired.
    6. Select the desired level of access for this key.
      You can select from the list of existing
      , or you can select
      to set the permissions on a more granular level. Roles are available according what was defined in the hub as described in Manage Roles.
    7. Generate
      the API Key.
    8. Copy ( ) the API key, and then click
      . This value represents your unique
      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.
  2. Get your Cortex XDR API Key ID.
    1. In the
      API Keys
      table, locate the
    2. Note your corresponding
      number. This value represents the
  3. Get your FQDN.
    1. Right-click your API key and select
      View Examples
    2. Copy the
      CURL Example
      URL. The example contains your unique FQDN:
      https://api-{fqdn}/public_api/v1/{name of api}/{name of call}/
    You can use the
    CURL Example
    URL to run the APIs.
  4. 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 ="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( * 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 ="https://api-{fqdn}/public_api/v1/{name of api}/{name of call}", headers=headers, json=parameters) return res
