Send Your First Request Using the API

To become familiar with the API, send some simple requests to Deep Security Manager.

Set up your development environment

The environment where you develop your software requires the following items:

  • Network access to a running Deep Security Manager, either one that you installed or one provisioned by Deep Security as a Service.
  • An SDK client library, if you choose to use one. Go to the Python SDK page, the JavaScript SDK page, or the Java SDK page to download the client library and learn how to add it to your development environment.
  • The runtime environment for the programming language of your client library.

To start exploring the API right away, instead of using a client library you can use an HTTP client such as Postman, Paw, or curl.

Authenticate with Deep Security Manager

Deep Security Manager uses API keys for authenticating HTTP requests. Each request that you make requires an api-secret-key header that contains a secret key, as in the following example request:

GET /api/policies HTTP/1.1
Host: localhost:4119
api-secret-key: 2:vJC6lckDygB6FYURIvR0WK2ZTAhIY8rb0Amy9UMn4mo=
api-version: v1

When using a client library, you obtain an instance of ApiClient and configure it to use your secret key. The configuration is global, so that all calls to the API thereafter are authenticated using the secret key. The GET and POST examples below show how to create and configureApiClient.

The manager uses the secret to authenticate your request. Each API key is associated with a role that determines the actions that you can perform.

Create an API key

Create an API key to use for authenticating your requests with Deep Security Manager. When you create an API key, you provide a name, the role to associate with the key, and optionally an expiry date. For more information, see Create and Manage API Keys.

To create an API key, you require the access rights to create users.

Upon creation of an API key, you are provided a unique secret key that is associated with the API key. You include this secret key in the HTTP request for authenticating. You must store the secret key when it is provided because at no other time are you able to obtain it. If you lose the secret you must create a new API key or create a new secret for the key.

The Creating a Trend Micro Deep Security API Key video steps you through the process.
  1. In Deep Security Manager, click Administration > User Management > System API Keys.
  2. Click New and enter the property values for the key.
  3. Click Next. The secret is presented. This is the only time that you can obtain the secret.
  4. Copy the secret and securely store it.
  5. Click Close.

Perform a GET request: list policies

To start exploring the API, go to the List Policies operation in the Policies section of the API reference. Notice that List Policies is a GET request on the policies endpoint:

get /policies

Use an HTTP client

To send the request right away use Postman, Paw, or curl. Use the following information to create the request:

  • URL: https://<Manager host name>:<port>/api/policies, for example https://localhost:4119/api/policies
  • First header:
    • Key: api-secret-key
    • Value: &lt;your key secret&gt;
  • Second header:
    • Key: api-version
    • Value: v1

Example curl command:

curl -X GET https:// localhost:4119/api/policies -H 'api-secret-key: 5:W+lC8YHIaYHeQuDbJZLkqwM5b8xjxla2pHtBNoiifF8=' -H 'api-version: v1'

If your Deep Security Manager is using a self-signed certificate to establish a secure connection, in the Postman settings, turn off SSL certificate verification. For Paw, in the Network preferences clear Validate SSL Certificates. For curl, include the --insecure option.

Use a client library

The following example code creates an ApiClient object that configures authentication with Deep Security Manager. A PoliciesApi object is then created and used to list all policies.

For the sake of clarity the example hard-codes authentication credentials, which is an extremely bad practice. Never hard-code your credentials.

Python
Use the following steps to run the example.
  1. Create a file named first_steps_get_example.py and copy the following example code to the file. 
    import deepsecurity as api
from deepsecurity.rest import ApiException as api_exception


def get_policies_list(api, configuration, api_version, api_exception):
    """ Gets a list of policies on the Deep Security Manager

    :return: A PoliciesApi object that contains a list of policies.
    """

    # Create a PoliciesApi object
    policies_api = api.PoliciesApi(api.ApiClient(configuration))

    # List policies using version v1 of the API
    policies_list = policies_api.list_policies(api_version)

    # View the list of policies
    return policies_list


if __name__ == '__main__':
    # Add Deep Security Manager host information to the api client configuration
    configuration = api.Configuration()
    configuration.host = 'https:// 192.168.17.149:4119/api'

    # Authentication
    configuration.api_key['api-secret-key'] = '2:l069trAePqPRxZUfBqyw442z1DWm9s4u0F/g9bewnFE='

    # Version
    api_version = 'v1'
    print(get_policies_list(api, configuration, api_version, api_exception))
  2. Locate the following code and change the URL and secret key according to your environment:
    • configuration.host = 'https://192.168.17.149:4119/api'
    • configuration.api_key['api-secret-key'] = '2:l069trAePqPRxZUfBqyw442z1DWm9s4u0F/g9bewnFE='
  3. Open a Command Prompt (Windows) or terminal (Linux) and enter the following command: 
    python first_steps_get_example.py
JavaScript
Use the following steps to run the example.
  1. Create a file named FirstStepsGetExample.js and copy the following example code to the file. 
    exports.getPolicies = function(hostNameAndPort, apiSecretKey) {
  return new Promise((resolve, reject) => {
    // Deep Security module
    const api = require("@trendmicro/deepsecurity");

    // Create the client
    const defaultClient = api.ApiClient.instance;
    defaultClient.basePath = "https:// " + hostNameAndPort + "/api";
    const defaultAuthentication = defaultClient.authentications["DefaultAuthentication"];
    defaultAuthentication.apiKey = apiSecretKey;

    // Allow connection that is 'secured' with self-signed certificate - for development only
    process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

    // Create a PoliciesApi object
    const policiesApi = new api.PoliciesApi();

    // List policies. Use version v1 of the API
    policiesApi.listPolicies("v1")
      .then(policies => {
        resolve(policies);
      })
      .catch(error => {
        reject(error);
      });
  });
};
  2. Create another file named App.js and copy the following code to the file: 
    const path = require("path");

const FirstStepsGetExample = require(path.resolve(__dirname, "./FirstStepsGetExample.js"));

FirstStepsGetExample.getPolicies("localhost:4119", "3:zNi5ag8xPGpfEMElV0GxAIpTs5Ji8BQoCtXaTAgKkVM=")
  .then( policies => {
    console.log(policies);
  })
  .catch(error => {
    console.log(error);
});
  3. In the App.js file, change the URL and secret key parameters of the call to FirstStepsGetExample.getPolicies according to your environment.
  4. Open a Command Prompt (Windows) or terminal (Linux) and enter the following command: 
    node App.js
  5. If you are seeing the error TypeError: Cannot read properties of undefined (reading 'text'), it means that the SDK cannot establish a connection between APIClient and the Deep Security Manager (DSM) host. Check that the DSM host name is correct.
    6. TypeError: Cannot read properties of undefined (reading 'text')

Perform a POST request: search firewall rules

Perform a POST request to search for firewall rules. In the API reference, the SearchFirewallRules operation (Firewall Rules section) for the firewallrules endoint is a POST request to the path firewallrules/search.

post /firewallrules/search

The API reference also shows a series of parameters that you use in the request body. For Search Firewall Rules, each parameter is a search criterium. In this example we search for the ID of 3.

Use an HTTP client to post

Use the following information to create the request in Postman or Paw:

  • Request type: POST
  • URL: https://<Deep Security Manager hostname>:<port>/api/firewallrules/search, for example https://localhost:4119/api/firewallrules/search
  • First header:
    • Key: api-secret-key
    • Value: your key secret
  • Second header:
    • Key: api-version
    • Value: v1
  • Third header:
    • Key:Content-Type
    • Value: application/json

Also, add the following raw code to the body:

{
  "searchCriteria": [{
    "idTest":"equal",
    "idValue":3
  }]
}

Example curl command:

curl -X POST https:// localhost:4119/api/firewallrules/search \
-H 'Cache-Control: no-cache' \
-H 'api-secret-key: 3:zNi5ag8xPGpfEMElV0GxAIpTs5Ji8BQoCtXaTAgKkVM=' \
-H 'api-version: v1' \
-H 'content-type: application/json' \
-d '{
  "searchCriteria": [{
    "idTest":"equal",
    "idValue":3
  }]
}'

Use a client library to post

The following example creates a SearchFilter object that defines search criteria. The SearchFilter object is then used as a parameter of thesearchFirewallRules method of aModuleFirewallApi object.

Python
Use the following steps to run the example.
    1. Create a file named first_steps_post_example.py and copy the following example code to the file. 
      import deepsecurity as api
from deepsecurity.rest import ApiException as api_exception


def search_firewall_rules(api, configuration, api_version, api_exception):
    """ Searches the firewall rules for any rule that contains DHCP in the rule name.

    :param api: The Deep Security API modules.
    :param configuration: Configuration object to pass to the api client.
    :param api_version: The version of the API to use.
    :param api_exception: The Deep Security API exception module.
    :return: A list containing all firewall rules that match the search criteria.
    """

    # Define the search criteria
    search_criteria = api.SearchCriteria()
    search_criteria.field_name = "name"
    search_criteria.string_value = "%DHCP%"

    # Perform the search
    firewall_rules = firewall_rules_api.search_firewall_rules(api_version, search_filter=search_filter)
    firewall_rules_list = []
    for rule in firewall_rules.firewall_rules:
