Getting started

Prerequisites

  • JDK 8 or later

To use this SDK, you will need to include the following dependencies:

For Apache Maven:

<dependency>
    <groupId>com.okta.sdk</groupId>
    <artifactId>okta-sdk-api</artifactId>
    <version>${okta.version}</version>
</dependency>
<dependency>
    <groupId>com.okta.sdk</groupId>
    <artifactId>okta-sdk-impl</artifactId>
    <version>${okta.version}</version>
    <scope>runtime</scope>
</dependency>
<dependency>
    <groupId>com.okta.sdk</groupId>
    <artifactId>okta-sdk-httpclient</artifactId>
    <version>${okta.version}</version>
    <scope>runtime</scope>
</dependency>

For Gradle:

compile "com.okta.sdk:okta-sdk-api:${okta.version}"
runtime "com.okta.sdk:okta-sdk-impl:${okta.version}"
runtime "com.okta.sdk:okta-sdk-httpclient:${okta.version}"

SNAPSHOT Dependencies

Snapshots are deployed off of the 'master' branch to OSSRH and can be consumed using the following repository configured for Apache Maven or Gradle:

https://oss.sonatype.org/content/repositories/snapshots/

You will also need:

Construct a client instance by passing it your Okta domain name and API token:

Client client = Clients.builder()
    .setOrgUrl("https://{yourOktaDomain}")  // e.g. https://dev-123456.okta.com
    .setClientCredentials(new TokenClientCredentials("{apiToken}"))
    .build();

Hard-coding the Okta domain and API token works for quick tests, but for real projects you should use a more secure way of storing these values (such as environment variables). This library supports a few different configuration sources, covered in the configuration reference section.

OAuth 2.0

Okta allows you to interact with Okta APIs using scoped OAuth 2.0 access tokens. Each access token enables the bearer to perform specific actions on specific Okta endpoints, with that ability controlled by which scopes the access token contains.

This SDK supports this feature only for service-to-service applications. Check out our guides to learn more about how to register a new service application using a private and public key pair.

When using this approach, you won't need an API Token because the SDK will request an access token for you. In order to use OAuth 2.0, construct a client instance by passing the following parameters:

Client client = Clients.builder()
    .setOrgUrl("https://{yourOktaDomain}")  // e.g. https://dev-123456.okta.com
    .setAuthorizationMode(AuthorizationMode.PRIVATE_KEY)
    .setClientId("{clientId}")
    .setScopes(new HashSet<>(Arrays.asList("okta.users.read", "okta.apps.read")))
    .setPrivateKey("/path/to/yourPrivateKey.pem")
    // (or) .setPrivateKey("full PEM payload")
    // (or) .setPrivateKey(Paths.get("/path/to/yourPrivateKey.pem"))
    // (or) .setPrivateKey(inputStream)
    // (or) .setPrivateKey(privateKey)
    .build();

Usage guide

These examples will help you understand how to use this library. You can also browse the full API reference documentation.

Once you initialize a Client, you can call methods to make requests to the Okta API.

Authenticate a User

This library should be used with the Okta management API. For authentication, we recommend using an OAuth 2.0 or OpenID Connect library such as Spring Security OAuth or Okta's Spring Boot integration. For Okta Authentication API you can use Authentication SDK.

Get a User

User user = client.getUser("a-user-id");

List all Users

UserList users = client.listUsers();

// stream
client.listUsers().stream()
    .forEach(user -> {
      // do something
    });

For more examples of handling collections see the paging section below.

Filter or search for Users

// search by email
UserList users = client.listUsers("jcoder@example.com", null, null, null, null);

// filter parameter
users = client.listUsers(null, "status eq \"ACTIVE\"", null, null, null);

Create a User

User user = UserBuilder.instance()
    .setEmail("joe.coder@example.com")
    .setFirstName("Joe")
    .setLastName("Code")
    .buildAndCreate(client);

Update a User

user.getProfile().setFirstName("new-first-name");
user.update();

Get and set custom attributes

Custom attributes must first be defined in the Okta profile editor. Then, you can work with custom attributes on a user:

user.getProfile().put("customPropertyKey", "a value");
user.getProfile().get("customPropertyKey");

Remove a User

user.deactivate();
user.delete();

List a User's Groups

GroupList groups = user.listGroups();

Create a Group

Group group = GroupBuilder.instance()
    .setName("a-group-name")
    .setDescription("Example Group")
    .buildAndCreate(client);

Add a User to a Group

user.addToGroup("groupId");

List a User's enrolled Factors

UserFactorList factors = user.listFactors();

Enroll a User in a new Factor

SmsUserFactor smsFactor = client.instantiate(SmsUserFactor.class);
smsFactor.getProfile().setPhoneNumber("555 867 5309");
user.enrollFactor(smsFactor);

Activate a Factor

UserFactor factor = user.getFactor("factorId");
ActivateFactorRequest activateFactorRequest = client.instantiate(ActivateFactorRequest.class);
activateFactorRequest.setPassCode("123456");
factor.activate(activateFactorRequest);

Verify a Factor

UserFactor factor = user.getFactor("factorId");
VerifyFactorRequest verifyFactorRequest = client.instantiate(VerifyFactorRequest.class);
verifyFactorRequest.setPassCode("123456");
VerifyUserFactorResponse verifyUserFactorResponse = factor.setVerify(verifyFactorRequest).verify();

List all Applications

ApplicationList applications = client.listApplications();

Get an Application

Application app = client.getApplication("appId");

Create a SWA Application

SwaApplication swaApp = client.instantiate(SwaApplication.class)
    .setSettings(client.instantiate(SwaApplicationSettings.class)
    .setApp(client.instantiate(SwaApplicationSettingsApplication.class)
      .setButtonField("btn-login")
      .setPasswordField("txtbox-password")
      .setUsernameField("txtbox-username")
      .setUrl("https://example.com/login.html")));

List System Logs

// page through all log events
LogEventList logEvents = client.getLogs();

// or use a filter (start date, end date, filter, or query, sort order) all options are nullable
logEvents = client.getLogs(null, null, null, "interestingURI.com", "ASCENDING");

Call other API endpoints

Not every API endpoint is represented by a method in this library. You can call any Okta management API endpoint using this generic syntax:

// Create an IdP, see: https://developer.okta.com/docs/api/resources/idps#add-identity-provider
ExtensibleResource resource = client.instantiate(ExtensibleResource.class);
ExtensibleResource protocolNode = client.instantiate(ExtensibleResource.class);
protocolNode.put("type", "OAUTH");
resource.put("protocol", protocolNode);
ExtensibleResource result = client.http()
    .setBody(resource)
    .post("/api/v1/idps", ExtensibleResource.class);

Thread Safety

Every instance of the SDK Client is thread-safe. You should use the same instance throughout the entire lifecycle of your application. Each instance has its own Connection pool and Caching resources that are automatically released when the instance is garbage collected.

Paging

Paging is handled automatically when iterating over a any collection.

// get the list of users
UserList users = client.listUsers();

// get the first user in the collection
log.info("First user in collection: {}", users.iterator().next().getProfile().getEmail());

// or loop through all of them (paging is automatic)
for (User tmpUser : users) {
    log.info("User: {}", tmpUser.getProfile().getEmail());
}

// or via a stream
users.stream().forEach(tmpUser -> log.info("User: {}", tmpUser.getProfile().getEmail()));

Inject the Okta Java SDK in Spring

To integrate the Okta Java SDK into your Spring Boot application you just need to add a dependency:

<dependency>
    <groupId>com.okta.spring</groupId>
    <artifactId>okta-spring-sdk</artifactId>
    <version>${okta.spring.version}</version>
</dependency>

Then define the following properties:

Key Description
okta.client.orgUrl Your Okta Url: https://{yourOktaDomain}, i.e. https://dev-123456.okta.com
okta.client.token An Okta API token, see creating an API token for more info.

NOTE: The configuration techniques described in the configuration reference section will work as well.

All that is left is to inject the client (com.okta.sdk.client.Client)! Take a look at this post for more info on the best way to inject your beans.

For more information check out the Okta Spring Boot Starter project!

Configuration reference

This library looks for configuration in the following sources:

  1. An okta.yaml at the root of the applications classpath
  2. An okta.yaml file in a .okta folder in the current user's home directory (~/.okta/okta.yaml or %userprofile%\.okta\okta.yaml)
  3. Environment variables
  4. Java System Properties
  5. Configuration explicitly set programmatically (see the example in Getting started)

Higher numbers win. In other words, configuration passed via the constructor will override configuration found in environment variables, which will override configuration in okta.yaml (if any), and so on.

YAML configuration

The full YAML configuration looks like:

okta:
  client:
    connectionTimeout: 30 # seconds
    orgUrl: "https://{yourOktaDomain}" # i.e. https://dev-123456.okta.com
    proxy:
      port: null
      host: null
      username: null
      password: null
    token: yourApiToken
    requestTimeout: 0 # seconds
    rateLimit:
      maxRetries: 4

When you use OAuth 2.0, the full YAML configuration looks like:

okta:
  client:
    connectionTimeout: 30 # seconds
    orgUrl: "https://{yourOktaDomain}" # i.e. https://dev-123456.oktapreview.com
    proxy:
      port: null
      host: null
      username: null
      password: null
    authorizationMode: "PrivateKey"
    clientId: "yourClientId"
    scopes: "okta.users.read okta.apps.read"
    privateKey: |
      -----BEGIN PRIVATE KEY-----
      b3BlbnNzaC1rZXktdjEAAAAABG5vbmUAAAAEbm9uZQAAAAAAAAABAAABFwAAAAdzc2gtcn
      ...b3BlbnNzaC1rZXktdjEAAAAAAAAAAAAABAAABFwAAAAdzc2gtcn-myN3AmcmmPMS...
      CO7Hnjlg77HRNFXPAAAAFWxrYW1pcmVkZHlAdm13YXJlLmNvbQECAwQF
      -----END PRIVATE KEY-----
    # or specify a path to a PEM file
    # privateKey: "/path/to/yourPrivateKey.pem" # PEM format. This SDK supports RSA AND EC algorithms - RS256, RS384, RS512, ES256, ES384, ES512.
    requestTimeout: 0 # seconds
    rateLimit:
      maxRetries: 4

Environment variables

Each one of the configuration values above can be turned into an environment variable name with the _ (underscore) character:

  • OKTA_CLIENT_CONNECTIONTIMEOUT
  • OKTA_CLIENT_TOKEN
  • and so on

System properties

Each one of the configuration values written in 'dot' notation to be used as a Java system property:

  • okta.client.connectionTimeout
  • okta.client.token
  • and so on

Connection Retry / Rate Limiting

By default, this SDK will retry requests that return with response code 503, 504, 429, or socket/connection exceptions.

Default configuration tells SDK to retry requests up to 4 times without time limitation:

okta.client.requestTimeout = 0 //Sets the maximum number of seconds to wait when retrying before giving up.
okta.client.rateLimit.maxRetries = 4 //Sets the maximum number of attempts to retrying before giving up.

For interactive clients (i.e. web pages) it is optimal to set requestTimeout to be 10 sec (or less, based on your needs), and the maxRetries attempts to be 0. This means the requests will retry as many times as possible within 10 seconds:

okta.client.requestTimeout = 10
okta.client.rateLimit.maxRetries = 0

or

import com.okta.sdk.client.Client;
import com.okta.sdk.client.Clients;

Client client = Clients.builder()
                .setRetryMaxElapsed(10)
                .setRetryMaxAttempts(0)
                .build();

For batch/non-interactive processes optimal values are opposite. It is optimal to set requestTimeout to be 0, and the maxRetries attempts to be 5. The SDK will retry requests up to 5 times before failing:

okta.client.requestTimeout = 0
okta.client.rateLimit.maxRetries = 5

If you need to limit execution time and retry attempts, you can set both requestTimeout and the maxRetries. For example, the following example would retry up to 15 times within 30 seconds:

okta.client.requestTimeout = 30
okta.client.rateLimit.maxRetries = 15

To disable the retry functionality you need to set both variables to zero:

okta.client.requestTimeout = 0
okta.client.rateLimit.maxRetries = 0

Caching

By default, a simple production-grade in-memory CacheManager will be enabled when the Client instance is created. This CacheManager implementation has the following characteristics:

  • It assumes a default time-to-live and time-to-idle of 1 hour for all cache entries.
  • It auto-sizes itself based on your application's memory usage. It will not cause OutOfMemoryExceptions.

The default cache manager is not suitable for an application deployed across multiple JVMs.

This is because the default implementation is 100% in-memory (in-process) in the current JVM. If more than one JVM is deployed with the same application codebase - for example, a web application deployed on multiple identical hosts for scaling or high availability - each JVM would have it's own in-memory cache.

As a result, if your application that uses an Okta Client instance is deployed across multiple JVMs, you SHOULD ensure that the Client is configured with a CacheManager implementation that uses coherent and clustered/distributed memory.

See the ClientBuilder Javadoc for more details on caching.

Caching for applications deployed on a single JVM

If your application is deployed on a single JVM and you still want to use the default CacheManager implementation, but the default cache configuration does not meet your needs, you can specify a different configuration. For example:

Caches.newCacheManager()
     .withDefaultTimeToLive(300, TimeUnit.SECONDS) // default
     .withDefaultTimeToIdle(300, TimeUnit.SECONDS) //general default
     .withCache(forResource(User.class) //User-specific cache settings
         .withTimeToLive(1, TimeUnit.HOURS)
         .withTimeToIdle(30, TimeUnit.MINUTES))
     .withCache(forResource(Group.class) //Group-specific cache settings
         .withTimeToLive(2, TimeUnit.HOURS))
     //... etc ...
     .build();

Disable Caching

While production applications will usually enable a working CacheManager as described above, you might wish to disable caching entirely. You can do this by configuring a disabled CacheManager instance. For example:

Client client = Clients.builder()
    .setCacheManager(Caches.newDisabledCacheManager())
    .build();

Building the SDK

In most cases, you won't need to build the SDK from source. If you want to build it yourself, take a look at the build instructions wiki (though just cloning the repo and running mvn install should get you going).
