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.

• Post issues here on GitHub (for code errors)

Getting started

To install the Okta Golang SDK in your project:

Version 2.x (Release) run go get github.com/okta/okta-sdk-golang/v2/okta

You'll also need

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

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

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

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.

Upgrading to 2.0.x

The main purpose of this version is to include all documented, application/json 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

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:

ctx, client, err := okta.NewClient(context,
  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 begining of each line.
)

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, 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 applicaiton users, delete and application user, and them listing them again.

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

appUserList, _, _ = client.Application.ListApplicationUsers(context.TODO(), appId, nil)

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

client.GetRequestExecutor().RefreshNext()
appUserList, _, _ = client.Application.ListApplicationUsers(context.TODO(), appId, nil)

Pagination

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

Exmaple 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)
}

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.

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

ctx, client, err := okta.NewClient(context, okta.WithOrgUrl("https://{yourOktaDomain}"), okta.WithToken("{apiToken}"))
user, resp, err := client.User.GetUser(user.Id, nil)

List all Users

ctx, client, err := okta.NewClient(context, okta.WithOrgUrl("https://{yourOktaDomain}"), okta.WithToken("{apiToken}"))
users, resp, err := client.User.ListUsers()

Filter or search for Users

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

filter := query.NewQueryParams(query.WithFilter("status eq \"ACTIVE\""))

users, resp, err := client.User.ListUsers(filter)

Create a User

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

p := &okta.PasswordCredential{
		Value: "Abcd1234",
}
uc := &okta.UserCredentials{
		Password: p,
}
profile := okta.UserProfile{}
profile["firstName"] = "John"
profile["lastName"] = "Activate"
profile["email"] = "john-activate@example.com"
profile["login"] = "john-activate@example.com"
u := &okta.User{
		Credentials: uc,
		Profile:     &profile,
}

user, resp, err := client.User.CreateUser(*u, nil)

Update a User

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

newProfile := *user.Profile
newProfile["nickName"] = "Batman"
updatedUser := &okta.User{
  Profile: &newProfile,
}
user, resp, err := client.User.UpdateUser(user.Id, *updatedUser, nil)

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:

ctx, client, err := okta.NewClient(context, okta.WithOrgUrl("https://{yourOktaDomain}"), okta.WithToken("{apiToken}"))
user, resp, err := client.User.GetUser(user.Id, nil)

nickName = user.Profile["nickName"]

Remove a User

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

ctx, client, err := okta.NewClient(context, okta.WithOrgUrl("https://{yourOktaDomain}"), okta.WithToken("{apiToken}"))
resp, err := client.User.DeactivateUser(user.Id, nil)

resp, err := client.User.DeactivateOrDeleteUser(user.Id, nil)

List a User's Groups

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

groups, resp, err := client.User.ListUserGroups(user.Id, nil)

Create a Group

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

gp := &okta.GroupProfile{
  Name: "Get Test Group",
}
g := &okta.Group{
  Profile: gp,
}
group, resp, err := client.Group.CreateGroup(*g, nil)

Add a User to a Group

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

resp, err := client.Group.AddUserToGroup(group.Id, user.Id, nil)

List a User's enrolled Factors

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

allowedFactors, resp, err := client.Factor.ListSupportedFactors(user.Id)

Enroll a User in a new Factor

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

factorProfile := okta.NewSmsFactorProfile()
factorProfile.PhoneNumber = "5551234567"

factor := okta.NewSmsFactor()
factor.Profile = factorProfile

addedFactor, resp, err := client.Factor.AddFactor(user.Id, factor, nil)

Activate a Factor

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

factor, resp, err := client.Factor.ActivateFactor(user.Id, factor.Id, nil)

Verify a Factor

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

verifyFactorRequest := okta.VerifyFactorRequest{
  PassCode: "123456"
}
verifyFactorResp, resp, err := client.Factor.VerifyFactor(user.Id, factor.Id, verifyFactorRequest, nil)

List all Applications

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

applications, resp, err := client.Application.ListApplications(nil)

//applications will need to be cast from the interface into its concrete form before you can use it.
for _, a := range applications {
		if a.(*okta.Application).Name == "bookmark" {
			if a.(*okta.Application).Id == app2.(okta.BookmarkApplication).Id {
				application :=  *a.(*okta.BookmarkApplication) //This will cast it to a Bookmark Application
			}
		}
		// continue for each type you want to work with.
	}

Get an Application

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

//Getting a Basic Auth Application
application, resp, err = client.Application.GetApplication(appId, okta.NewBasicAuthApplication(), nil)

//To use the application, you must cast it to the type.
app := application.(*okta.BasicAuthApplication)

Create a SWA Application

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

swaAppSettingsApp := newSwaApplicationSettingsApplication()
swaAppSettingsApp.ButtonField = "btn-login"
swaAppSettingsApp.PasswordField = "txtbox-password"
swaAppSettingsApp.UsernameField = "txtbox-username"
swaAppSettingsApp.Url = "https://example.com/login.html"
swaAppSettingsApp.LoginUrlRegex = "REGEX_EXPRESSION"

swaAppSettings := newSwaApplicationSettings()
swaAppSettings.App = &swaAppSettingsApp

swaApp := newSwaApplication()
swaApp.Label = "Test App"
swaApp.Settings = &swaAppSettings

application, resp, err := client.Application.CreateApplication(swaApp, nil)

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:

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

url := "https://golang.oktapreview.com/api/v1/authorizationServers

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"},
}

req, err := m.client.requestExecutor.NewRequest("POST", url, as)
if err != nil {
  return nil, nil, err
}

var authServer *AuthorizationServer
resp, err := m.client.requestExecutor.Do(req, &authServer)
if err != nil {
  return nil, resp, err
}
return authServer, resp, nil

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.GetRequestExecutor()

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:

0. An okta.yaml file in a .okta folder in the current user's home directory (~/.okta/okta.yaml or %userprofile\.okta\okta.yaml)
1. A .okta.yaml file in the application or project's root directory
2. Environment variables
3. 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
        THQdM5PIlot6XmeV1KUKuzw2ewDeb5zcasA4QHPcSVh2+KzbttPQ+RUXCUAr5t+r
        0r6gBc5Dy1IPjCFsqsPJXFwqe3RzUb...
        -----END RSA PRIVATE KEY-----
    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

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
