This repository contains the Okta management SDK for Golang. This SDK can be used in your server-side code to interact with the Okta management API and

Create and update users with the Users API
Add security factors to users with the Factors API
Manage groups with the Groups API
Manage applications with the Apps API
Much more!

We also publish these libraries for Golang:

JWT Verifier

You can learn more on the Okta + Golang page in our documentation.

Getting started

The SDK is compatible with Go version 1.12.x and up. For SDK v2 and above, you must use Go Modules to install the SDK.

Install current release

To install the Okta Golang SDK in your project:

Create a module file by running go mod init
- You can skip this step if you already use go mod
Run go get github.com/okta/okta-sdk-golang/v2@latest. This will add the SDK to your go.mod file.
Import the package in your project with import "github.com/okta/okta-sdk-golang/v2/okta"

Installing legacy version

Although we do not suggest using the 1.x version of the SDK, you can still use it. Version 1.x is retiring and will not be supported past March 4, 2021. It will likely remain working after that date, but you should make a plan to migrate to the new 2.x version.

You can install v1 of the SDK by running go get github.com/okta/okta-sdk-golang@latest and import the package in your project with import "github.com/okta/okta-sdk-golang"

You'll also need

An Okta account, called an organization (sign up for a free developer organization if you need one)
An API token

Initialize a client

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

import (
	"fmt"
	"context"
	"github.com/okta/okta-sdk-golang/v2/okta"
)

func main() {
  ctx, client, err := okta.NewClient(
    context.TODO(),
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

  fmt.Printf("Context: %+v\n Client: %+v\n",ctx, client)
}

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.

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. Most methods are grouped by the API endpoint they belong to. For example, methods that call the Users API are organized under client.User.

Caching

In the default configuration the client utilizes a memory cache that has a time to live on its cached values. See Configuration Setter Object WithCache(cache bool), WithCacheTtl(i int32), and WithCacheTti(i int32). This helps to keep HTTP requests to the Okta API at a minimum. In the case where the client needs to be certain it is accessing recent data; for instance, list items, delete an item, then list items again; be sure to make use of the refresh next facility to clear the request cache. See Refreshing Cache for Specific Call. To completely disable the request memory cache configure the client with WithCache(false).

NOTE: Regardless of cache manager, Access Tokens from OAuth requests are always cached.

Connection Retry / Rate Limiting

By default this SDK retries requests that are returned with a 429 exception. To disable this functionality set OKTA_CLIENT_REQUEST_TIMEOUT and OKTA_CLIENT_RATELIMIT_MAXRETRIES to 0.

Setting only one of the values to zero disables that check. Meaning, by default, four retry attempts will be made. If you set OKTA_CLIENT_REQUEST_TIMEOUT to 45 seconds and OKTA_CLIENT_RATELIMIT_MAXRETRIES to 0. This SDK will continue to retry indefinitely for 45 seconds. If both values are non zero, this SDK attempts to retry until either of the conditions are met (not both).

We use the Date header from the server to calculate the delta, as it's more reliable than system time. But always add 1 second to account for some clock skew in our service:

backoff_seconds = header['X-Rate-Limit-Reset'] - header['Date'] + 1s

If the backoff_seconds calculation exceeds the request timeout, the initial 429 response will be allowed through without additional attempts.

When creating your client, you can pass in these settings like you would with any other configuration.

import (
	"fmt"
	"context"
	"github.com/okta/okta-sdk-golang/v2/okta"
)

func main() {
  ctx, client, err := okta.NewClient(
    context,
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
    okta.WithRequestTimeout(45),
    okta.WithRateLimitMaxRetries(3),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

  fmt.Printf("Context: %+v\n Client: %+v\n",ctx, client)
}

Authenticate a User

This library should only be used with the Okta management API. To call the Authentication API, you should construct your own HTTP requests.

Get a User

import (
	"fmt"
	"context"
	"github.com/okta/okta-sdk-golang/v2/okta"
)

func main() {
  ctx, client, err := okta.NewClient(
    context.TODO(),
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

  fmt.Printf("Context: %+v\n Client: %+v\n",ctx, client)

  user, resp, err := client.User.GetUser(ctx, "{UserId|Username|Email}")
  if err != nil {
    fmt.Printf("Error Getting User: %v\n", err)
  }
  fmt.Printf("User: %+v\n Response: %+v\n\n",user, resp)
}

List all Users

    context.TODO(),
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

	}

	fmt.Printf("Filtered Users: %+v\n Response: %+v\n\n", filteredUsers, resp)

	for index, user := range filteredUsers {
		fmt.Printf("User %d: %+v\n", index, user)
	}
}

Create a User

import (
	"fmt"
	"context"
	"github.com/okta/okta-sdk-golang/v2/okta"

	}

	profile := okta.UserProfile{}
	profile["firstName"] = "Ben"
	profile["lastName"] = "Solo"
	profile["email"] = "[email protected]"
	profile["login"] = "[email protected]"

	createUserRequest := okta.CreateUserRequest{

	}


	// activate user on create
	queryParam := query.NewQueryParams(query.WithActivate(true))


	user, resp, err := client.User.CreateUser(ctx, createUserRequest, queryParam)
	if err != nil {
		fmt.Printf("Error Creating User: %v\n", err)
	}

	fmt.Printf("User: %+v\n Response: %+v\n\n", user, resp)

	}

	fmt.Printf("Updated User: %+v\n Response: %+v\n\n", updatedUser, resp)
}

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 the same as any other profile attribute

Remove a User

You must first deactivate the user, and then you can delete the user.

import (
	"fmt"
	"context"
	"github.com/okta/okta-sdk-golang/v2/okta"
)

func main() {
  ctx, client, err := okta.NewClient(
    context.TODO(),
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

  fmt.Printf("Context: %+v\n Client: %+v\n",ctx, client)

  resp, err := client.User.DeactivateUser(ctx, "00u14ffhw5szVqide0h8", nil)
	if err != nil {
		fmt.Printf("Error deactivating user: %v\n", err)
	}

	fmt.Printf("Response: %+v\n\n", resp)

	resp, err = client.User.DeactivateOrDeleteUser(ctx, "00u14ffhw5szVqide0h8", nil)

	}

	fmt.Printf("Application: %+v\n Response: %+v\n\n", application, resp)
}

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:

import (
	"fmt"
	"context"
  "time"
	"github.com/okta/okta-sdk-golang/v2/okta"
)

func main() {
  ctx, client, err := okta.NewClient(
    context.TODO(),
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithToken("{apiToken}"),
  )

  if err != nil {
    fmt.Printf("Error: %v\n", err)
  }

  fmt.Printf("Context: %+v\n Client: %+v\n",ctx, client)

  // The URL you want to call (org url will be automatically prefixed)
  url := "/api/v1/authorizationServers"

  // Set up the body of the request with structs and data
	type Signing struct {
		RotationMode string     `json:"rotationMode,omitempty"`
		LastRotated  *time.Time `json:"lastRotated,omitempty"`
		NextRotation *time.Time `json:"nextRotation,omitempty"`
		Kid          string     `json:"kid,omitempty"`
	}

	type Credentials struct {
		Signing *Signing `json:"signing,omitempty"`
	}

	type AuthorizationServer struct {
		Id          string       `json:"id,omitempty"`
		Name        string       `json:"name,omitempty"`
		Description string       `json:"description,omitempty"`
		Audiences   []string     `json:"audiences,omitempty"`
		Issuer      string       `json:"issuer,omitempty"`
		IssuerMode  string       `json:"issuerMode,omitempty"`
		Status      string       `json:"status,omitempty"`
		Created     *time.Time   `json:"created,omitempty"`
		LastUpdated *time.Time   `json:"lastUpdated,omitempty"`
		Credentials *Credentials `json:"credentials,omitempty"`
		Embedded    interface{}  `json:"_embedded,omitempty"`
		Links       interface{}  `json:"_links,omitempty"`
	}

	as := AuthorizationServer{
	Name:        "Sample Authorization Server",
	Description: "Sample Authorization Server description",
	Audiences:   []string{"api://default"},
	}

  // create a new request using the cloned request executor
	req, err := client.CloneRequestExecutor().NewRequest("POST", url, as)
	if err != nil {
		fmt.Printf("Error creating new request: %v\n", err)
	}

  // Make the request
	var authServer *AuthorizationServer
	resp, err := client.CloneRequestExecutor().Do(ctx, req, &authServer)
	if err != nil {
		fmt.Printf("Error executing request: %v\n", err)
	}

	fmt.Printf("Authorization Server: %v\n Response: %v\n\n", authServer, resp)
}

Access Request Executor

If you need to gain access to the request executor, we have provided a method off the Client to do so.

re := client.CloneRequestExecutor()

Doing this will provide you with the ability to create your own requests for the Okta API and call the Do method that handles all of the headers for you based on the configuration.

Configuration reference

This library looks for configuration in the following sources:

An okta.yaml file in a .okta folder in the current user's home directory (~/.okta/okta.yaml or %userprofile\.okta\okta.yaml)
A .okta.yaml file in the application or project's root directory
Environment variables
Configuration explicitly passed to the constructor (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

When you use an API Token instead of OAuth 2.0 the full YAML configuration looks like:

okta:
  client:
    connectionTimeout: 30 # seconds
    orgUrl: "https://{yourOktaDomain}"
    proxy:
      port: null
      host: null
      username: null
      password: null
    token: {apiToken}

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

okta:
  client:
    connectionTimeout: 30 # seconds
    orgUrl: "https://{yourOktaDomain}"
    proxy:
      port: null
      host: null
      username: null
      password: null
    authorizationMode: "PrivateKey"
    clientId: "{yourClientId}"
    scopes:
      - scope.1
      - scope.2
    privateKey: |
        -----BEGIN RSA PRIVATE KEY-----
        MIIEogIBAAKCAQEAl4F5CrP6Wu2kKwH1Z+CNBdo0iteHhVRIXeHdeoqIB1iXvuv4

        -----END RSA PRIVATE KEY-----
    privateKeyId: "{JWK key id (kid}" # needed if Okta service application has more then a single JWK registered
    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

Upgrading to 2.0.x

The main purpose of this version is to include all documented, application/json content-type endpoints to the SDK. During this update we have made many changes to method names, as well as method signatures.

Context

Every method that calls the API now has the ability to pass context.Context to it as the first parameter. If you do not have a context or do not know which context to use, you can pass context.TODO() to the methods.

Method changes

We have spent time during this update making sure we become a little more uniform with naming of methods. This will require you to update some of your calls to the SDK with the new names.

All methods now specify the Accept and Content-Type headers when creating a new request. This allows for future use of the SDK to handle multiple Accept types.

OAuth 2.0 With Private Key

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.

Access Tokens are always cached and respect the expires_in value of an access token response.

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. Otherwise, follow the example steps at the end of this topic.

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:

ctx := context.TODO()
ctx, client, err := okta.NewClient(ctx,
  okta.WithOrgUrl("https://{yourOktaDomain}"),
  okta.WithAuthorizationMode("PrivateKey"),
  okta.WithClientId("{{clientId}}"),
  okta.WithScopes(([]string{"okta.users.manage"})),
  okta.WithPrivateKey({{PEM PRIVATE KEY BLOCK}}), //when pasting blocks, use backticks and remove all space at beginning of each line.
  okta.WithPrivateKeyId("{{private key id}}"),    //needed if Okta service application has more then a single JWK registered
)
if err != nil {
  fmt.Printf("Error: %v\n", err)
}

fmt.Printf("Context: %+v\n Client: %+v\n\n",ctx, client)

Example

Let's say the need is to authenticate a script that will run in a pipeline (or any other automated way), and instead of using an API Token (that is bound to a user) the goal is to use a service app.

A public/private key pair is required to do so.

These are the requirements:

a public/private key par in JWT format (reference)
a service app that uses the created key (reference)
store the private key in a PEM format (reference)

To store the PEM formatted key with new lines in a JSON file, the multiple lines need to be one-line formatted by joining them with the "\n" character. The awk command makes this formatting quick and precise:

awk 'NF {sub(/\r/, ""); printf "%s\\n",$0;}' private.pem

Steps

The mkjwk can be used to create your keys. If generating production keys, only use mkjwk running locally after you have audited their code.

Save the three files, for example named as public-key, public-private-keypair and public-private-keypair-set.

Now create the PEM formatted private key. [pem-jwk](https://www.npmjs.com/package/pem-jwk) can be utilized to do the PEM formatting. Be sure to audit the pem-jwk code before trusting it with production values.

pem-jwk public-private-keypair > private.pem

Create the service app following Okta's guide "Create a service app and grant scopes > Create a service app", using public-private-keypair-set.

Use the Okta web console to grant the scopes as usual.

To complete our example the PEM formatted private key will be stored in a JSON file so your app can read it at run time. If this is the PEM formatted key:

}

The file can be read from Go and used directly in the client creation:

ctx := context.TODO()
ctx, client, err := okta.NewClient(ctx,
  okta.WithOrgUrl("https://{yourOktaDomain}"),
  okta.WithAuthorizationMode("PrivateKey"),
  okta.WithClientId("{client_id}"),
  okta.WithScopes([]string{"{scopes}"}),
  okta.WithPrivateKey("{private_key}"),
  okta.WithPrivateKeyId("{private key id}"), //needed if Okta service application has more then a single JWK registered
  )

OAuth 2.0 With JWT Key

Access Tokens are always cached and respect the expires_in value of an access token response.

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:

ctx := context.TODO()
ctx, client, err := okta.NewClient(ctx,
  okta.WithOrgUrl("https://{yourOktaDomain}"),
  okta.WithAuthorizationMode("JWT"),
  okta.WithClientAssertion("{{clientAssertion}}"),
  okta.WithScopes(([]string{"okta.users.manage"})),
)
if err != nil {
  fmt.Printf("Error: %v\n", err)
}

fmt.Printf("Context: %+v\n Client: %+v\n\n",ctx, client)

This is very similar to PrivateKey Authorization Mode with a caveat, instead of providing public/privatekey pair, you can use a pre-signed JWT instead

OAuth 2.0 With Bearer Token

Okta SDK supports authorization using a Bearer token. A bearer token is an ephemeral token issued by Okta via supported Okta apps. Exchanging provisioned credentials for a bearer token may involve external dependencies that are out of scope for the SDK to support natively.

Bearer Token Scope

Bearer tokens are scoped to an application and not to the greater organization as is enabled when the SDK is initialized with an Okta SSWS token or an OAuth private key. Therefore a bearer token will not have the permissions to perform all of the API calls for organization management through the SDK. The scope of the bearer token is determined by the scope configured on the Okta app and the scope requested during the authorization. Care should be taken by the implementers to configure the Okta app with the necessary scopes for the integration.

Implementation Steps

Create an Okta app based on your requirements. The following table lists the apps types that issue Bearer tokens.

Sign-in method	Application Type	Details
OIDC - OpenID Connect	Web Application	Authorization code flow with client secret
OIDC - OpenID Connect	Single-Page Application	Authorization code flow with PKCE
OIDC - OpenID Connect	Native Application	Authorization code flow with client secret or Authorization code flow with PKCE
API Services	N/A	Natively supported by SDK using `PrivateKey` Authorization mode

Make a call to the Org Authorization Server endpoint to get the authorization code.
Exchange authorization code for a Bearer token.

Instantiate and use Okta client with Bearer token.

ctx, client, err := okta.NewClient(
    ctx,
    okta.WithOrgUrl("https://{yourOktaDomain}"),
    okta.WithAuthorizationMode("Bearer"),
    okta.WithClientId("{client_id}"),
    okta.WithToken("{token}"),
  )

A bearer token is scoped implicitly, so there is no need to provide okta.WithScopes() config setter method when initializing the Okta client.

Extending the Client

When calling okta.NewClient() we allow for you to pass custom instances of http.Client and cache.Cache.

myClient := &http.Client{}

myCache := NewCustomCacheDriver()

ctx, client, err := okta.NewClient(
  context.TODO(),
  okta.WithOrgUrl("https://{yourOktaDomain}"),
  okta.WithToken("{apiToken}"),
  okta.WithHttpClient(myClient),
  okta.WithCacheManager(myCache)
)

Extending or Creating New Cache Manager

You can create a custom cache driver by implementing cache.Cache

type CustomCacheDriver struct {
}

func NewCustomCacheDriver() Cache {
	return CustomCacheDriver{}
}

func (c CustomCacheDriver) Get(key string) *http.Response {
	return nil
}

func (c CustomCacheDriver) Set(key string, value *http.Response) {}

func (c CustomCacheDriver) Delete(key string) {}

func (c CustomCacheDriver) Clear() {}

func (c CustomCacheDriver) Has(key string) bool {
	return false
}

Refreshing Cache for Specific Call

If you have an issue where you do a GET, then a DELETE, and then re-issue a GET to the original endpoint, you may have an issue with the cache returning with the deleted resource. An example of this is listing application users, delete an application user, and then listing them again.

You can solve this by running client.CloneRequestExecutor().RefreshNext() before your second ListApplicationUsers call, which will tell the call to delete the cache for this endpoint and make a new call.

appUserList, resp, err := client.Application.ListApplicationsUsers(ctx, nil)

client.Application.DeleteApplicationUser(context.TODO(), appId, appUser.Id, nil)

client.CloneRequestExecutor().RefreshNext()
appUserList, resp, err := client.Application.ListApplicationsUsers(ctx, nil)

Pagination

If your request comes back with more than the default or set limit, you can request the next page.

Example of listing users 1 at a time:

query := query.NewQueryParams(query.WithLimit(1))
users, resp, err := client.User.ListUsers(ctx, query)
// Do something with your users until you run out of users to iterate.
if resp.HasNextPage() {
  var nextUserSet []*okta.User
  resp, err = resp.Next(ctx, &nextUserSet)
}

Building the SDK

In most cases, you won't need to build the SDK from source. If you want to build it yourself, you'll need these prerequisites:

Clone the repo
Run make build from the root of the project
