Usage guide

All usage of this SDK begins with the creation of a client, the client handles the authentication and communication with the Okta API. To create a client, you need to provide it with your Okta Domain and an API token. To obtain those, see Getting Started With the Okta APIs.

We also include an opt-in default request executor that you can configure, which will automatically handle rate limiting retries for you:

const okta = require('@okta/okta-sdk-nodejs');

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc'    // Obtained from Developer Dashboard
});

It is also possible to provide configuration through environment variables or YAML files. Please see Configuration for examples.

All interactions with the Okta Platform API is done through client methods. Some examples are below, but for a full list of methods please refer to the JsDoc page for the Client.

OAuth 2.0 Authentication

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. Please read this guide 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:

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  authorizationMode: 'PrivateKey',
  clientId: '{oauth application ID}',
  scopes: ['okta.users.manage'],
  privateKey: '{JWK}' // <-- see notes below
});

The privateKey can be passed in the following ways:

  • As a JSON encoded string of a JWK object
  • A string in PEM format
  • As a JSON object, in JWK format

Note: in case OAuth client app uses multiple JWKs, privateKey should specify kid attribute.

Examples

Users

Create a User

The Users: Create User API can be used to create users. The most basic type of user is one that has an email address and a password to login with, and can be created with the client.createUser() method:

const newUser = {
  profile: {
    firstName: 'Foo',
    lastName: 'Bar',
    email: 'foo@example.com',
    login: 'foo@example.com'
  },
  credentials: {
    password: {
      value: 'PasswordAbc123'
    }
  }
};

client.createUser(newUser)
.then(user => {
  console.log('Created user', user);
});

Get a User

The Users: Get User API can be used to fetch a user by id or login (as defined on their profile.login property), and is wrapped by client.getUser(:id|:login):

client.getUser('ausmvdt5xg8wRVI1d0g3')
.then(user => {
  console.log(user);
});

client.getUser('foo@bar.com')
.then(user => {
  console.log(user);
});

Update a User

Once you have a user instance, you can modify it and then call the update() method to persist those changes to the API. This uses the Users: Update User API:

user.profile.nickName = 'rob';
user.update()
.then(() => console.log('User nickname change has been saved'));

Delete a User

Before deleting an Okta user, they must first be deactivated. Both operations are done with the Users: Lifecycle Operations API. We can chain the deactivate() and delete() operations on the user instance to achieve both calls:

user.deactivate()
.then(() => console.log('User has been deactivated'))
.then(() => user.delete())
.then(() => console.log('User has been deleted'));

List All Org Users

The client can be used to fetch collections of resources, in this example we'll use the Users: List Users API. When fetching collections, you can use the each() method to iterate through the collection. For more information see Collection.

const orgUsersCollection = client.listUsers();

orgUsersCollection.each(user => {
  console.log(user);
})
.then(() => console.log('All users have been listed'));

You can also use async iterators.

for await (let user of client.listUsers()) {
    console.log(user);
}

For more information about this API see Users: Get User.

Search for Users

The Users: List Users API provides three ways to search for users, q, filter, or search, and all of these approaches can be achieved by passing them as query parameters to the client.listUser() method. The library will URL-encode the values for you.

client.listUsers({
  q: 'Robert'
}).each(user => {
  console.log('User matches query: ', user);
});

client.listUsers({
  search: 'profile.nickName eq "abc 1234"'
}).each(user => {
  console.log('User matches search:', user);
});

client.listUsers({
  filter: 'lastUpdated gt "2017-06-05T23:00:00.000Z"'
}).each(user => {
  console.log('User matches filter:', user);
});

Groups

Create a Group

The Groups: Add Group API allows you to create Groups, and this is wrapped by client.createGroup(:newGroup):

const newGroup = {
  profile: {
    name: 'Admin Users Group'
  }
};

client.createGroup(newGroup)
.then(group => {
  console.log('Created group', group);
});

Assign a User to a Group

With a user and group instance, you can use the addToGroup(:groupId) method of the user to add the user to the known group:

user.addToGroup(group.id)
.then(() => console.log('User has been added to group'));

Applications

Create An Application

The Applications: Add Application API allows you to create Okta Applications. There are many different types of applications that can be created. Please refer to the Applications documentation for details about each application type and what is required when creating the application.

In this example, we create a Basic Authentication Application:

const application = {
  name: 'template_basic_auth',
  label: 'Sample Basic Auth App',
  signOnMode: 'BASIC_AUTH',
  settings: {
    app: {
      url: 'https://example.com/auth.htm',
      authURL: 'https://example.com/login.html'
    }
  }
};

client.createApplication(application)
.then(application => {
  console.log('Created application:', application);
});

Assign a User to an Application

To assign a user to an application, you must know the ID of the application and the user:

client.assignUserToApplication(createdApplication.id, {
  id: createdUser.id
})
.then(appUser => {
  console.log('Assigned user to app, app user instance:' appUser);
});

An App User is created, which is a new user instance that is specific to this application. An App User allows you define an application-specific profile for that user. For more information please see Applications: User Operations and Applications: Application User Profile.

Assign a Group to an Application

To assign a group to an application, you must know the ID of the application and the group:

client.createApplicationGroupAssignment(createdApplication.id, createdGroup.id);

Sessions

Create a Session

This is a rarely used method. See Sessions: Create Session with Session Token for the common ways to create a session. To use this method, you must have a sessionToken:

client.createSession({
  sessionToken: 'your session token'
})
.then(session => {
  console.log('Session details:' session);
});

Get a Session

To retrieve details about a session, you must know the ID of the session:

client.getSession(session.id)
.then(session => {
  console.log('Session details:' session);
});

These details include when and how the user authenticated and the session expiration. For more information see Sessions: Session Properties and Sessions: Session Operations.

Refresh a Session

To refresh a session before it expires, you must know the ID of the session:

client.refreshSession(session.id)
.then(session => {
  console.log('Refreshed session expiration:', session.expiresAt);
});

End a Session

To end a session, you must know the ID of the session:

client.endSession(session.id)
.then(() => {
  console.log('Session ended');
});

End all Sessions for a User

To end all sessions for a user, you must know the ID of the user:

client.clearUserSessions(user.id)
.then(() => {
  console.log('All user sessions have ended');
});

System Log

Get logs

To query logs, first get a collection and specify your query filter:

const collection = client.getLogs({ since: '2018-01-25T00:00:00Z' });

Please refer to the System Log API Documentation for a full query reference.

If you wish to paginate the entire result set until there are no more records, simply use each() to paginate the collection. The promise will resolve once the first empty page is reached.

If you wish to continue polling the collection for new results as they arrive, then start a subscription:

const collection = client.getLogs({ since: '2018-01-24T23:00:00Z' });

const subscription = collection.subscribe({
  interval: 5000, // Time in ms before fetching new logs when all existing logs are read
  next(logItem) {
    // Do something with the logItem
  },
  error(err) {
    // HTTP/Network Request errors are given here
    // The subscription will continue unless you call subscription.unsubscribe()
  },
  complete() {
    // Triggered when subscription.unsubscribe() is called
  }
});

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:

const okta = require('@okta/okta-sdk-nodejs');

// Assumes configuration is loaded via yaml or environment variables
const client = new okta.Client();

// https://developer.okta.com/docs/reference/api/apps/#preview-saml-metadata-for-application
const applicationId = '{your custom SAML app id}';
const url = `${client.baseUrl}/api/v1/apps/${applicationId}/sso/saml/metadata`;
const request = {
  method: 'get',
  headers: {
    'Accept': 'application/xml',
    'Content-Type': 'application/json',
  }
};

client.http.http(url, request)
  .then(res => res.text())
  .then(text => {
    console.log(text);
  })
  .catch(err => {
    console.error(err);
  });

Collection

When the client is used to fetch collections of resources, a collection instance is returned. The collection encapsulates the work of paginating the API to fetch all resources in the collection (see Pagination). The collection provides the each() method for iterating over the collection, as described below.

each()

Allows you to visit every item in the collection, while optionally doing work at each item. All calls to each() will return a promise that is resolved when all items have been visited or rejected if you return a rejected promise from your iterator. Iteration can be stopped by rejecting a returned promise, or by returning false (will not cause a promise rejection). The following examples show you the various use-cases.

Serial or Parallel Synchronous Work

If no value is returned, each() will continue to the next item:

client.listUsers().each(user => {
  console.log(user);
  logUserToRemoteSystem(user);
})
.then(() => {
  console.log('All users have been visited');
});
Serial Asynchronous Work

Returning a promise will pause the iterator until the promise is resolved:

client.listUsers().each(user => {
  return new Promise((resolve, reject) => {
    // do work, then resolve or reject the promise
  })
});
Ending Iteration

Returning false will end iteration:

client.listUsers().each(user => {
  console.log(user);
  return false;
})
.then(() => {
  console.log('Only one user was visited');
});

Returning false in a promise will also end iteration:

client.listUsers().each(user => {
  console.log(user);
  return Promise.resolve(false);
})
.then(() => {
  console.log('Only one user was visited');
});

Rejecting a promise will end iteration with an error:

return client.listUsers().each(user => {
  console.log(user);
  return Promise.reject('foo error');
}).catch(err => {
  console.log(err); // 'foo error'
});

subscribe(config)

A subscription allows you to continue paginating a collection until new items are available, if the REST API supports it for the collection. The only supported collection is the System Log API at this time.

A subscription fetches pages until the first empty page is reached. From that point, it fetches a new page at an interval in milliseconds defined by config ({ interval: 5000 }). This interval defaults to 5000 milliseconds. A subscription object is returned. To terminate polling, call unsubscribe() on the subscription object.

Depending on the polling interval you choose, you may run into rate limiting exceptions. In that case you should enable our rate limiting retry strategy, see Rate Limiting.

Simple subscription example
const subscription = collection.subscribe({
  interval: 5000,
  next(item) {
    console.log(item);
  },
  error(err) {
    // handle error
  }
});

// In the future, unsubscribe when you want to stop polling:
subscription.unsubscribe()

Configuration Reference

There are several ways to provide configuration to the client constructor. When creating a new client, the following locations are searched in order, in a last-one-wins fashion:

  1. An okta.yaml file in ~/.okta.
  2. An okta.yaml file in the current working directory of the node process.
  3. Environment variables
  4. Properties passed to the client constructor

As such, you can create a client without passing a configuration option, e.g. new okta.Client(), so long as you have provided the configuration in one of the other locations.

If providing a yaml file, the structure should be the same as the properties that you pass to the client constructor:

okta:
  client:
    orgUrl: 'https://dev-1234.oktapreview.com/',
    token: 'xYzabc'

If providing environment variables, the configuration names are flattened and delimited with underscores:

OKTA_CLIENT_ORGURL=https://dev-1234.oktapreview.com/
OKTA_CLIENT_TOKEN=xYzabc

Caching

To speed up your service, we enable caching by default to prevent unnecessary requests. Both caching storage and caching strategy are configurable. You'll want to configure your cache when your service is distributed across more than one server.

Storage

By default, the SDK uses an in-memory cache, MemoryStore.

By default, expired keys are only removed on attempted retrieval. If a key is never retrieved, it will remain in the cache, which may grow until it hits maximum size.

To prevent this behavior, and instead remove expired values from memory proactively, set a value for expirationPoll and the MemoryStore will periodically scan the entire store in memory to remove expired keys.

const okta = require('@okta/okta-sdk-nodejs');
const MemoryStore = require('@okta/okta-sdk-nodejs/src/memory-store');

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc', // Obtained from Developer Dashboard
  cacheStore: new MemoryStore({
    keyLimit: 100000,
    expirationPoll: true
  })
});

MemoryStore configuration options:

  • keyLimit - Max number of keys stored (default is 100000). The oldest keys are deleted as new keys are set.
  • expirationPoll - The time, in milliseconds, between memory scans. If the value is true, a value of 15000 is used. (default is false, no scanning)

Custom Storage

It's easy to build your own cache store, just conform to this interface:

class CustomStore {
  async get(stringKey) {}
  async set(stringKey, stringValue) {}
  async delete(stringKey) {}
}

Middleware

The default caching middleware caches any resource that has a self link, and invalidates the cache for any non-GET requests affecting that resource. If you'd like to disable caching entirely, set cacheMiddleware to null:

const okta = require('@okta/okta-sdk-nodejs');

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc', // Obtained from Developer Dashboard
  cacheMiddleware: null
});

Custom Middleware

Custom middleware provides very granular control to manage caching. Middleware is simply a function that accepts a context and a callback:

async function customMiddleware(ctx, next) {
  // do something before the request
  await next();
  // do something after the response
}

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc', // Obtained from Developer Dashboard
  cacheMiddleware: customMiddleware
});

The context contains:

  • req - An object containing details about the request:
    • uri
    • method
    • body
  • res - An object containing details about the response. This is the same interface as a response you'd receive from fetch.
  • isCollection - Whether the response is expected to be a collection.
  • resources - An array of resource URIs affected by the request.
  • cacheStore - A reference to the cache store.

If res is attached to the context before next is called, then a request will not be made. In order to attach a res, do the following:

const OK = 200;
async function customMiddleware(ctx, next) {
  const text = 'someText';
  ctx.res = {
    status: OK,
    text() { return Promise.resolve(text); }
  };
  await next(); // will skip external request
}

Note: default cache middleware implementation does not cache collections requests as there is no one-size-fits-all solution for keeping track of modified/deleted items within collections. Developers should provide their own cache middleware implementation for collection caching.

Rate Limiting

The Okta API will return 429 responses if too many requests are made within a given time. Please see Rate Limiting at Okta for a complete list of which endpoints are rate limited. When a 429 error is received, the X-Rate-Limit-Reset header will tell you the time at which you can retry. This section discusses methods for handling rate limiting with this SDK.

Built-In Retry

You can configure your client to use the default request executor if you wish to automatically retry on 429 errors, please the Default Request Executor section.

Note: in the next major version the default request executor will be automatically added to the client.

Manual Retry

If you wish to manually retry the request, you can do so by reading the X-Rate-Limit-Reset header on the 429 response. This will tell you the time at which you can retry. Because this is an absolute time value, we recommend calculating the wait time by using the Date header on the response, as it is in sync with the API servers, whereas your local clock may not be. We also recommend adding 1 second to ensure that you will be retrying after the window has expired (there may be a sub-second relative time skew between the X-Rate-Limit-Reset and Date headers).

Header parsing example

This example shows you how to determine how long you should wait before retrying the request. You then must decide how many times you would like to retry, and how you would like to call the client method again (not shown):

client.createUser()
  .catch(err => {
    if (err.status == 429) {
      const retryEpochMs = parseInt(err.headers.get('x-rate-limit-reset'), 10) * 1000;
      const retryDate = new Date(retryEpochMs);
      const nowDate = new Date(err.headers.get('date'));
      const delayMs = retryDate.getTime() - nowDate.getTime() + 1000;
      // Wait until delayMs has passed before retrying the request
    }
  });

Request Executor

This SDK uses the concept of a request executor, the RequestExecutor class, which is a base class that is responsible for making HTTP requests to the API and fulfilling the responses for the client. This class is a simple proxy to the isomorphic-fetch library.

In addition to the base RequestExecutor, the SDK ships with a "default" request executor, DefaultRequestExecutor, which is used by default and extends the base with 429 retry logic.

You can create your own executor or extend one of ours, which allows you to define global logic for all HTTP requests made by this library. Please see the Building a Custom Request Executor section for more information.

Default Request Executor

See DefaultRequestExecutor for the class code.

The default executor extends the base executor and will automatically retry requests if a 429 error is returned. Using these configuration options, you can configure your retry tolerance for your specific use case:

  • maxRetries - The number of times to retry, defaults to 2. Set to 0 if you do not want to limit the number of retries.
  • requestTimeout - How long to wait before giving up on the request, regardless of how many retries are made. Defined in milliseconds and defaults to 0, which disables the request timeout.
const customDefaultRequestExecutor = new okta.DefaultRequestExecutor({
  maxRetries: 2,
  requestTimeout: 0 // Specify in milliseconds if needed
})

const client = new okta.Client({
  orgUrl: 'https://dev-1234.okta.com/',
  token: 'xYzabc',    // Obtained from Developer Dashboard
  requestExecutor: customDefaultRequestExecutor
});

Because the rate limits are different for different endpoints you may need to change the default configuration, or create multiple clients with different executor configurations.

To help with debugging and logging, the default executor will emit a backoff event when a retry request has been scheduled, and resume event when that request begins:

defaultRequestExecutor.on('backoff', (request, response, requestId, delayMs) => {
  console.log(`Backoff ${delayMs} ${requestId}, ${request.url}`);
});

defaultRequestExecutor.on('resume', (request, requestId) => {
  console.log(`Resume ${requestId} ${request.url}`);
});

The requestId and delayMs values are pulled from the request and passed as parameters for convenience.

Base Request Executor

See RequestExecutor for the class code.

The base request executor does nothing more than delegate the request to the isomorphic-fetch library, and emit the request and response events. This class has no configuration. The client will use this executor if none is provided. In the next major version you will need to explicitly pass this executor if you wish to opt-out of the default executor:

const client = new okta.Client({
  orgUrl: 'https://dev-1234.oktapreview.com/',
  token: 'xYzabc',    // Obtained from Developer Dashboard
  requestExecutor: new okta.RequestExecutor()
});

The base executor also emits request and response events, these can be useful for debugging and request logging:

const client = new okta.Client({
  // uses the base executor by default
});

client.requestExecutor.on('request', (request) => {
  console.log(`Request ${request.url}`);
});

client.requestExecutor.on('response', (response) => {
  console.log(`Response ${response.status}`);
});

Building a Custom Request Executor

There are two ways you can design your own executor:

  • Extend one of our executors.
  • Create a class that implements the fetch method in the same way as RequestExecutor.

As an example, let's say you want to use our default 429 retry behavior, but you want to add some logging to understand how long requests are taking, including retry time. To do this, you can extend DefaultRequestExecutor, then re-implement the fetch() method with your custom logic, while still delegating the actual call to DefaultRequestExecutor:

class DefaultExecutorWithLogging extends okta.DefaultRequestExecutor {
  fetch(request) {
    const start = new Date();
    console.log(`Begin request for ${request.url}`);
    return super.fetch(request).then(response => {
      const timeMs = new Date() - start;
      console.log(`Request complete for ${request.url} in ${timeMs}ms`);
      return response;
    });
  }
}

const client = new okta.Client({
  requestExecutor: new DefaultExecutorWithLogging()
})
